FORT WORTH, Texas, Dec. 13, 2024 (GLOBE NEWSWIRE) -- CorVel Corporation (NASDAQ: CRVL) announces that its Board of Directors approved a three-for-one forward stock split of its common stock. The Board also approved a proportionate increase in the number of authorized shares of common stock to accommodate the stock split. The Board did not approve an increase in the number of authorized shares of preferred stock. The implementation of the stock split and authorized share increase is subject to the filing of an amendment to the Company’s Fourth Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which the Company expects to file on December 24, 2024. “Our stock price has seen extraordinary growth over the past several years fueled by our strong financial performance and the successful execution of our strategic plan. We believe it is the right time to effect a forward stock split to increase the accessibility of our stock to potential investors while maintaining our focus on delivering our customers enhanced technological solutions for the management of their healthcare needs,” said Michael G. Combs, the Company’s President, Chief Executive Officer and Chairman of the Board. Following the filing and effectiveness of the amendment, every one share of common stock outstanding or held in treasury on December 23, 2024, the record date for the stock split, will be split into three shares of common stock. Subject to final approval by the Nasdaq Global Select Market, trading is currently expected to begin on a post-stock split adjusted basis at market open on December 26, 2024.

So why, at 37 years old, does the best tennis player in the world, and arguably in the history of the sport, need a coach? Long relationship ... Andy Murray and Novak Djokovic when they played doubles together at the Australian Open in 2006. Credit: Getty Images It was a surprise when Djokovic named long-time rival Andy Murray as his new coach – a player Djokovic had a 69 per cent win record against – and the duo are set to make their debut at the Brisbane International in January before Djokovic heads to the Australian Open to chase his 25th grand slam title. But former champion-turned-Nine commentator Todd Woodbridge says the pairing isn’t as strange as it seems. “It’s intriguing. Andy Murray for me is this generation’s Lleyton Hewitt, and Ken Rosewell before him, and I say that because they just live, eat, breathe tennis,” Woodbridge says. “Andy can’t keep away from it.” Murray retired from professional tennis in 2024 as a three-time grand slam champion and two-time Olympic gold medallist. And while Djokovic had the upper hand in their head-to-head matches, beating Murray 25 of the 36 times they played, Woodbridge says Murray was the same calibre of athlete. “Andy played everyone that Novak is going to be playing against. So, they’ll be drawing up strategy, game plan, tactics, and what they’ve got to do is find ways for Novak to win matches really quickly, succinctly, keeping energy in the tank, and I think that’s part of the reason he’s been brought along. “But, you know, there’s one more [reason], which is very obvious, and that’s that Novak has had people around him in his last two coaching roles that have been there, done it... So that’s Boris Becker and Goran Ivanisevic. It is impossible to hire someone to come in and tell him things, when he’s already done more than they have. And Andy is on a parallel [with] him.
Legendary reality television star, model and businesswoman Kim Kardashian is taking heat for her "shameful" lingerie photoshoot this weekend. Kardashian, who has more than 350 million followers on Instagram, is no stranger to going viral on social media. She is constantly posting photos of herself and her brands to her various accounts. But one SKIMS photoshoot posted on Sunday, in partnership with Dolce & Gabbana, is being called out for being "shameful" and "insensitive." A lightly dressed Kardashian posed with an impressive-looking rosary. Kim K/Instagram But is it appropriate for Kim Kardashian to be posing in something like that with lingerie? "why is she always wearing the cross when she’s half naked ... like wtaf," one fan wrote. "Uhm have you ever done a research on rosary before take a half nude picture with?? That’s beyond shameful of your action!" one fan added. "The Rosary isn't jewelry," one fan added. "Pls don't play with the Holy Rosary," one fan added. "Sadistic," one fan added. "Why don’t you just get naked!!!!! Such hypocrisy stripping while wearing a cross!!!! So bored of your desperation 😳🤔🤔," one fan added. View the original article to see embedded media. At the end of the day, though, Kim Kardashian got what she wanted - attention for the post. That's what she and her family members are best at and the social media world keeps eating it up, one way or another. What do you make of her controversial photoshoot on Sunday?
Kendrick Lamar and Mustard are cooking with fish grease once again, this time on "tv off." This collaboration follows the incredible and historic success of "Not Like Us," the dagger diss record from the tense beef with Drake . It finds a home on K. Dot's brand-new surprise album GNX which hit streaming out of the blue on Friday, November 22. This is a great way to capitalize on the hype of the aforementioned West Coast anthem, but also to build upon these two's chemistry going forward. "tv off" might seem very similar to "Not Like Us" on the surface, especially with the triumphant horn sections and contagious energy. However, the lyrical content is a great contrast and secretly plays into the track's theme of deceit, superficiality, and more. Lamar mentioned on "The Day The Party Died" how he wanted to reset the culture that we are experiencing in rap right now. This GNX cut almost feels like a pseudo-sequel in some ways, as he mentions how social media ruins people's perceptions, society's questionable decisions and how they impact the world, and more. It might a stretch on our part, but this is what Kendrick's music allows for.

The Prison Reform Trust (PRT), a charity that was led by Lord Timpson until he was appointed prisons minister in July, said that prisoners should be involved in both the design and delivery of officer training and development programmes, while former prisoners should help to recruit officers and support them during their induction. Detailed interviews with prisoners in jails across the country found that inmates consistently identified building rapport as the most crucial skill for effective prison officers. However, the report warned that the prison service stands at a “crucial turning point”, with only a minority of current staff having direct experience of the traditional relationship-based model of prison management that has historically characterised the system in England and Wales. It said there should be more opportunities for prisoners and staff to build relationships through shared activities such as cooking, a recommendation widely backed by the inmates consulted as part of research.UNITED NATIONS (AP) — Israeli airstrikes hit Yemen’s main airport as a civilian Airbus 320 with hundreds of passengers on board was landing and a U.N. delegation was waiting to leave, the U.N.'s top humanitarian official in Yemen said Friday. Julien Harneis told U.N. reporters that the most frightening thing about the two airstrikes on Thursday wasn’t their effect on him and about 15 others in the VIP lounge at the international airport in Yemen's capital, Sanaa, including the head of the U.N. World Health Organization. Rather, it was the destruction of the airport control tower as a Yemenia Airways plane was taxiing in after touching down. “Fortunately, that plane was able to land safely and the passengers were able to disembark, but it could have been far, far worse,” said Harneis, who was with WHO Director-General Tedros Adhanom Ghebreyesus in the lounge . He said one airstrike landed approximately 300 meters (330 yards) south of the VIP lounge and another about 300 meters to the north around 4:45 p.m., while about five members of the U.N. team were outside the building. “Not only obviously did we have zero indication of any potential airstrikes, but we cannot remember the last time there were airstrikes in Sanaa during daylight hours,” Harneis said in a video news conference from Sanaa. The U.N. said at least three people were killed and dozens injured in the strike. Among the injured was a crew member from the U.N. Humanitarian Air Service, which was about to fly the U.N. delegation of some 20 people out of Sanaa. He suffered a serious leg injury from shrapnel and lost a lot of blood, Harneis said. Immediately after the airstrikes, Harneis said, U.N. security officials moved the delegation out of the VIP building and into five armored cars where they waited for approximately 40 minutes to ascertain what happened and help the injured crew member. He was taken to a hospital in Sanaa and underwent four hours of surgery while the rest of the delegation spent the night in a U.N. compound, Harneis said. The U.N. plane with Tedros and the U.N. team, including the injured crew member, was able to depart for Jordan on Friday afternoon – without an operating control tower. The United Nations said the injured crew member was taken to a hospital in Jordan, and Tedros was heading back to Geneva, where WHO is based, Yemen’s Iran-backed Houthi rebels, who control Sanaa and much of the country’s north, have gone after Israel since it started attacking Gaza following the Oct. 7, 2023 attacks by Gaza's Hamas militants on southern Israel. The Houthis have attacked ships in the Red Sea, disrupting one of the world’s main maritime routes, and recently stepped up missile and drone attacks on Israel . Israel has escalated its response. The Israeli army said it wasn’t aware that the WHO chief or U.N. delegation were at the Sanaa airport on Thursday. Israel said it bombed the airport because it is used by the Houthis and Iran. Harneis responded, stressing that the airport is civilian, not military, and is used for transporting U.N. and other humanitarian workers, and for one civilian flight — Yemenia to and from Amman, Jordan. The flight operates as a result of an international agreement, and thousands of Yemenis have used the flight to get advanced medical treatment abroad, he said. Yemen is the Arab world’s poorest nation and has been engulfed in a 10-year civil war between the Houthi rebels, who control Sanaa and much of the country's north, and the internationally recognized government forces in the south. Tedros was in the country to discuss its worsening humanitarian crisis and to seek the release of about 50 people detained by the Houthis since June from the U.N., nongovernmental organizations and civil society. Harneis said 18 million Yemenis — about half the country’s population — need humanitarian assistance this year, and the U.N. expects the number to increase to 19 million next year because of the worsening economy . In addition to airstrikes on the Sanaa airport, Israel has been attacking the country's key port of Hodeida, in western Yemen. Harneis said Yemen relies on imports through Hodeida for 80% of its food and more than 90% of its medical supplies to the north. A recent Israeli airstrike destroyed two tugboats and is estimated to have reduced the harbor's capacity by 50%, the U.N. official said, while damage from Thursday's airstrikes hasn't been assessed yet. As for the detainees, Harneis said he joined the WHO chief at meetings with the Houthi prime minister, foreign minister and a member of the group's Supreme Political Council. He said they received commitments on the detainees' possible release and a pathway to it, and on conditions under which they are being held.

I don’t imagine many people would contradict me if I said that Halcro’s Eclipse power amplifier – in either its or stereo version – is the most immediately recognisable amplifier in the world. It is so recognisable that in a pitch-black room it can quickly and easily be identified by touch alone. The Halcro Eclipse is also – albeit this time arguably – the most beautiful amplifier in the world, which is undoubtedly one of the reasons it has featured on the front covers of so many hi-fi magazines around the world, including here in Australia. The story behind the amplifier’s design is also one of the most interesting and unusual in audio. The intellect behind Halcro’s creation, and indeed the brand’s name, was South African physicist and engineer Dr Bruce Halcro Candy (you can see why he used his middle name!), who after founding the company and becoming world-famous for the very first amplifier he built (the Halcro dm58) was then head-hunted by Minelab, famous for its hand-held metal detectors, after which the company languished as no more than a listing in the Australian government’s official register of company names. It languished on that list until one sunny Saturday morning, when Lance Hewitt, who had been Candy’s lead engineer, was adding to his collection of vinyl at a South Australian record store. The store’s owner, who knew that Hewitt had formerly worked for Halcro, introduced him to Mike Kirkham of Magenta Audio, an Australian audio equipment importer, retailer and distributor who also happened to be at the record store buying vinyl that very same morning. Hewitt told Kirkham not only that he had been personally responsible for building and testing Halcro amplifiers but also that he happened to know that all of the circuit diagrams, PCBs and tooling required to build them were gathering dust in a storage facility – indeed, one not far from where they were chatting. The result of this serendipitous Saturday morning meet was that Halcro became resurrected as a going entity. Kirkham contacted Dr Peter Foster, a friend of his who holds a PhD in physics from the University of Adelaide and was formerly a Senior Laser Physicist at Norseld Pty Ltd and a Guest Scientist at the University of Bayreuth, Germany. The result was the trio founding a new company, Longwood Audio, which in 2015 acquired all of Halcro’s assets, including the brand name, the company’s portfolio of patents and the all-essential machine tooling along with a batch of unsold mothballed stock. Foster is now Longwood Audio’s CEO; Kirkham is its Head of Sales and Marketing; and Hewitt is in charge of development and manufacturing. Build & technology The ‘look’ of the Eclipse Stereo is directly copied from the design of the original Halcro dm38, which was the work of Adelaide designers Tony Kearney and Max Dickison. Candy’s brief to them was that, to ensure the correct operation of the amplifier, the electronics had to be separated into four heavily shielded modules – an audio power module, an audio drive module, an inductor module and a power supply module – and that, in order to remove the heat passively without using fans, the heatsinks for the output devices had to be extraordinarily large. Those very design elements have been incorporated in the Eclipse Stereo. One important change, however, has been in the execution of the heatsink design. the original’s design was microphonic so that at certain frequencies it could vibrate so significantly that its resonances were audible in the listening room. The heatsinks on the Eclipse Stereo, however, are non-resonant by virtue of being completely redesigned. The new design sees each section fabricated from up to 10mm-thick folded aluminium, with the winged sections fully damped and the joins connecting the horizontal chambers to the wing sections. The non-wooden sections of the chassis now come in either a ‘Standard’ powder-coat finish or a premium hand-painted ‘Signature’ finish, too. If you are at all familiar with Halcro amplifiers, you will already have an inkling of how large the Eclipse Stereo’s chassis is; if you’re not, let me point out that a person of average height, when standing upright, will not need to lean down to touch one of the amplifier’s vertical wings. Checking out the amplifier’s proportions in the images accompanying this review should also give you an idea of how wide the amplifier is, but just to make it perfectly clear, the Halcro Eclipse Stereo power amplifier is not only 79cm tall but also as wide as it is deep (40cm). It’s not lightweight either, tipping the scales at 62kg. (And, when eyeing the images, don’t miss the fact that the shape of the chassis actually forms the capital letter ‘H’, which is pretty clever!) The internal circuitry of the Halcro Eclipse Stereo inherits DNA from the original Halcro dm38, as well as from the , but according to Hewitt, while some things have been lost (such as the current mode inputs), many other aspects of the circuitry have been improved – some are the natural result of improvements in technology, some are the result of improvements in circuit layouts, and some are the result of research and development by Longwood Audio itself, for which Hewitt says the company has been awarded four patents. Candy was always secretive about the circuitry of the Halcro dm38, and Longwood Audio is continuing this tradition. CEO Peter Foster told Paul Miller of : “We never release schematics [and] every circuit has the component designators engraved off and the boards are coated in an epoxy layer to further mask what’s going on”. he was nonetheless able to glean the following information about the Eclipse Stereo: “ ” Further details of how the circuit might work are revealed in US Patent 6,600,367, which was granted to Candy and is currently assigned to Longwood Audio: " " Also interesting are some of the patent’s citations, which reference an active bias circuit for operating push-pull amplifiers in Class A mode (granted to one Nelson Pass), a distortion-free complemented error feedback amplifier method (granted to James Strickland), and reducing amplifier distortion by comparison of input and feedback from output (granted to Barry Elliot Porter). The patent also directly cites one Douglas H. Self. (For readers who are unfamiliar with these names, any audio engineer asked to name the world’s top five audio amplifier designers of the last 50 years would include three of those names.) Input and output connections are made on the module at the top of the amplifier, at the rear. The Eclipse Stereo has both unbalanced (via gold-plated RCA) and balanced (via gold-plated XLR) inputs, plus a ‘low gain’ unbalanced input. The speaker cable terminals are absolutely huge, and while they’re supposed to be combination spade/banana types, the only way I could see to use banana plugs was to remove the rubberised cap on the knob – but I wasn’t prepared to risk damaging it trying to pry it off! Halcro has built several sophisticated automated protection systems into the Eclipse Stereo to prevent it from being damaged by a variety of issues that could impact its performance, covering everything from power supply stability to problems that could affect the output stages. Longwood Audio says that the Halcro Eclipse Stereo amplifier “ ”. Even the standby switch is air-pressure activated rather than a traditional electrical switch, to minimise interference. It’s good that there’s such a high level of overkill on the protection front, because the company’s secrecy about its circuits, including the values of the components used in those circuits, would mean that any fault could only be addressed by a technician with insider knowledge. Otherwise, the amplifier would need to be returned to South Australia – and given its size and weight, that would be rather an expensive exercise! Listening sessions My first audio experience of the Halcro Eclipse Stereo during testing was by way of an initial warm-up using music from a band with which I have a love/hate relationship: GoGo Penguin. Delivering amazing sound for what is essentially just a trio (percussion, bass and keys), the band’s music has been described as a form of jazz for the modern age – but then again, is it? I love the sound but hate not being able to define exactly why it’s so mesmerisingly great, and find the group hard to recommend to others because their music is so polarising. What I can say with certainty is that it really helps if you are listening to their music through an amplifier with the high performance of the Eclipse Stereo. For example, the double-bass on (from the album ‘A Humdrum Star’) is not only beautifully captured in terms of sounding just like a double-bass should, but it’s also just a lovely bass line – so inventive that you really can’t foretell the next note, as you can with performances by many lesser bassists. In delivering this line so well, Nick Blacka provides a unique counterpoint to Chris Illingworth’s gloriously grand pianism, even though you can sometimes foretell what note Illingworth is going to play next because he plays so many that are the same! The complexity of the sound is jaw-dropping, and the scattergun drumming of Rob Turner (who’s since been replaced by Jon Scott) is epic, and beautifully delivered by the Halcro. On , the following track, you’ll hear Blacka’s double-bass sounding like nothing you’ve ever heard before, as he delivers miraculous high-frequency overtones that make a mockery of the instrument’s normally accepted frequency range. The Eclipse Stereo delivers the entire gamut perfectly – the delivery is sonically contiguous, despite the rarity of the nature of the sound. When the drum kit comes in, at about 1:30, the accuracy with which the amplifier delivers the kick drum sound in exact syncopation with the high-hat strikes, all while keeping each in its own sonic envelope, and with no unwanted overhang, is an object lesson in the importance of state-of-the-art amplification in an audio reproduction chain. The Halcro Eclipse also maintained the ‘airiness’ of the acoustic as a constant throughout – a subtlety that eludes lesser amplifiers. The buzzy, insect-like opening to highlighted for me the complete lack of background noise from the Eclipse Stereo’s circuitry – the amplifier makes no noise at all other than what is actually in the audio signal delivered to it. There is no low-frequency hum, no high-frequency hiss, and absolutely no modulation of the lowest-level background sounds on a track. Such sounds issue from an inky-black silence that is so silent it’s almost mesmerising in and of itself. The simplicity of the percussion and piano on this track is a musical antidote to what has gone before, and the crystalline clarity of the sound I heard from the Eclipse Stereo was simply amazing, a testament to the complete lack of audible distortion. I do need to warn you that I think GoGo Penguin has gone somewhat off-piste with their latest album, ‘Everything Is Going To Be OK’ – both sonically and musically – so if you want to hear what I heard, I recommend sticking with the four albums the band recorded with Blue Note, which include ‘Man Made Object’ and the aforementioned ‘A Humdrum Star’. If you’d rather test out the Halcro Eclipse Stereo’s enormous power reserves and bass delivery with music that’s not so ‘out there’, I recommend revisiting – or listening to for the first time! – Talking Heads’ 1983 classic album ‘Speaking In Tongues.’ The funky bass sound is deep and tight, and Chris Frantz’s drum, beautifully captured on this recording, sounds as real as can be. Obviously, you’d listen to opener at a high volume, but you should also crank up the dial while listening to in order to hear how well the Eclipse Stereo can deliver the eclectic and varied synthesizer sounds on this track at any volume level you care to listen at. Listen, too, to how well the left and right channels are separated. Indeed channel separation is so complete that I could easily have been convinced that I was auditioning a pair of Eclipse Monos instead! You can hear not only the channel separation but also the beautiful stereo imaging of the Eclipse Stereo on where the vocals are trademark Talking Heads timbre and the purity of the percussion sound is exemplary, particularly the ‘found instrument’ sounds delivered by David Van Tieghem. I had lots of fun working out the various ‘found instruments’ he was playing. I have often written in the pages of magazine that the piano is the best instrument with which to evaluate audio components due to its enormous pitch compass, supreme dynamics and the fact that it’s a stringed percussive instrument, and you could have no better music to hear all of this than that on French pianist Alexandre Tharaud’s 2009 recording of more than 70 works by Erik Satie. This, of course, includes the famous Gnossiennes, but here they are strangely interwoven with other lesser-known works, in such a way that it’s as if you’re hearing them for the first time. Indeed some of these works you may actually be hearing for the first time, because it was Satie, not John Cage, who invented the ‘prepared piano’, and unlike many pianists, Tharaud follows Satie’s instructions to the letter in by placing sheets of paper on the upper octave strings. I can’t say I liked the result, but the Eclipse Stereo certainly reproduced it faithfully. Elsewhere on this recording, Tharaud’s playful execution of Satie’s more conventional scores is certainly more entertaining than the performances delivered by more sedate pianists. Verdict The Halcro Eclipse Stereo is not only the most recognisable amplifier in the world, along with being one of the most beautiful, but it is also the quietest and has the lowest distortion of all. If you think that is part and parcel of what makes it one of the best-sounding amplifiers in the world, I’m not about to disagree. You may, however, be surprised to learn that the Eclipse Stereo is not one of the most expensive hi-fi amplifiers in the world. In fact, it’s not even close – dozens of its competitors have price tags in excess of $150,000! In light of this information, you should realise that the Halcro Eclipse Stereo could be considered good value even at twice its price. Laboratory Test Report Steve Holding, Newport Test Labs. Halcro rates the per-channel power output of the Eclipse Stereo as 180 watts into eight ohms and 350 watts into four ohms. With the Eclipse Stereo on its test bench, measured the 1kHz power output at 202 and 386 watts per channel into eight and four ohms respectively, so the power amplifier bettered its specification for both test loads. As you can see from the tabulated results, power output dropped to 196 watts into eight ohms when the test frequency was dropped down to 20Hz (when driving two channels), and to 365 watts when both channels were driven into four ohms at this same 20Hz frequency. While these are lower than the 1kHz power output results, they’re still comfortably higher than Halcro’s specification. measured the frequency response of the Eclipse Stereo as being 3dB down at 3.5Hz and 280kHz, so this is a very wide-band amplifier design. It’s also a superbly linear one, as evidenced by the 1dB down-points of 6.5Hz and 90kHz, meaning the normalised frequency response is 6.5Hz – 90kHz ±0.5dB. As you would expect, the frequency response was even flatter across the audio band. This response (Graph 1 above) shows that it’s around 0.1dB down at 20Hz and 20kHz, for a normalised response of 20Hz – 20kHz ±0.05dB. This frequency response was, as per industry standards, measured when the Eclipse Stereo was driving an eight-ohm test resistor. On this graph you would normally expect to find a second trace showing the amplifier’s response when driving a more complex load, one that simulates the load that a loudspeaker would present. In fact, that trace is there – you just can’t see it because it perfectly overlays the response into a resistor. This is the first time has ever measured this theoretically ‘perfect’ result! Separation between the two stereo channels was outstandingly good, as you can see from the accompanying result table – 86dB at 20Hz, 101dB at 1kHz, and 78dB at 20kHz. Also outstandingly good was the level matching of the two channels, with measuring a difference of just 0.01dB. Inter-channel phase accuracy was also exceptionally good, with errors of only 0.02° at 20Hz, 0.08° at 1kHz and 1.17° at 20kHz. The result at 20kHz may seem to be an outlier, but you should bear in mind that a result of 1.0° at this frequency would be a world-beating achievement. Measuring the level of distortion on an audio signal that is introduced by a Halcro amplifier is a near-impossible task because it is so low that it is supremely difficult to measure. You not only need a test instrument capable of making the measurement but also a signal generator that has lower distortion than both the amplifier and the test instrument. To illustrate the difficulty, look at Graph 2 above, which shows the distortion components inherent in the output of ’ best signal generator. You can see that there’s a second harmonic distortion component at –117dB (0.00014%), a third HD component at –122dB (0.00007%) and a fifth at –128dB (0.00003%). So if we used this generator to provide the signal to measure the Eclipse Stereo’s distortion and saw a result that exhibited these same distortion components, at around the same levels, we would know only that the Halcro was not adding unwanted distortion. Indeed this is exactly what we see in Graph 3, which shows the output spectrum of the Eclipse Stereo when it’s delivering this same 1kHz signal but amplified to a level of one watt into eight ohms. Essentially, the only difference is that the amplifier has added just a little distortion at 3kHz, so that it is at –120dB instead of –122dB. (The result was exactly the same when the Eclipse Stereo was driving a four-ohm load.) The other thing to note with Graph 3 (because it will be significant later) is that there is some noise visible at the bottom of the graph, however as you can see from the scale at the left, the noise is 140dB below the one-watt reference level, which is so low that it would be totally and completely inaudible under any conditions. Graph 4 shows distortion (and noise!) levels measured by when the Halcro Eclipse Stereo was delivering 1kHz into eight ohms at a power level of 20 watts. Again, you can see that the distortion ‘signature’ is essentially that of the test signal generator, so the Eclipse Stereo is not adding any distortion to the test signal itself. Note, too, that there is now no audio band noise visible on the graph, so the Halcro’s audio band noise is now well below 140dB. There is some noise visible (the single narrow peak at the extreme left of the graph), which is from the amplifier’s power supply, but it’s more than 120dB down. Again, the result when the Eclipse Stereo was tested into a four-ohm load at this frequency and power output was exactly the same as it was into the eight-ohm load. Graph 5 shows an extreme test case for distortion, which here is shown when the Eclipse Stereo is delivering 1kHz into an eight-ohm load at its full rated power (180 watts). The result is mind-bogglingly (and I mean that in its truest sense) good. As you would expect, there is absolutely zero noise in the output other than that tiny leakage from the power supply, and the distortion levels are almost unchanged from that shown in the one-watt and 20-watt graphs. The level of the third harmonic has risen slightly so that distortion component is now sitting at –117dB, which is 0.00014%. The fifth-order component has also risen by 1dB to –127dB (0.00004%). The result of ’ testing aligns with Halcro’s claims that the Eclipse Stereo’s THD levels are “better than –120dB”, a lever that it points out is “lower than 1000 parts per billion”. The distortion result shown in the accompanying test result table tells the THD story in an easily understandable numeric form: 0.00006%. The level of intermodulation distortion (CCIF-IMD) measured by is shown in Graph 6 above, when the Eclipse Stereo was delivering twin 19kHz and 20kHz test signals at a level of 20 watts into eight ohms. There are only two high-frequency sidebands, at 18kHz and 21kHz, that are each 110dB down and so would contribute 0.0003% to the output – insignificantly small. There is a tiny regenerated signal down at 1kHz too, but it is also insignificantly small – 117dB down, contributing only 0.00014%. All other signals are more than 120dB down, which is the level specified by Halcro for this particular test. The overall wide-band signal-to-noise ratios measured by were, as we’re sure you’ve already guessed from the noise floors shown in the graphs, spectacularly low. Noise relative to an output level of one watt was measured at –101dB unweighted, and –107dB A-weighted. We can’t think of a single amplifier the lab has measured that has ever come within cooee of returning a noise figure better than 100dB when referenced to this power level. The noise figures were better again for the measurement at rated output, with the Halcro returning results of –124dB unweighted, and –130dB A-weighted. As one who is ‘experienced in the art’ would expect from Graph 1, the output impedance of the Eclipse Stereo was incredibly low, with measuring it as 0.002 ohms at 1kHz, which is an order of magnitude better than almost all other amplifiers and means a damping factor of 4,000! Square wave testing reflected the results returned when measuring the Eclipse Stereo’s frequency response, with the tilt on the 100Hz square wave reflecting the –3dB point of 3.5Hz (Halcro specs it at 3Hz). There’s no bending so there’s no low-frequency phase shift. The waveform at 1kHz is so squared-off and clean that it may as well have been issued directly from the lab’s function generator, and is therefore a perfect result. At a 10kHz test frequency there is some rounding evident on the leading edge of the waveform, reflecting the high-frequency 3dB down-point of 280kHz, but the overall rise time shows a very, very fast slew rate. The Eclipse Stereo’s ability to drive extremely demanding loudspeakers, as well as electrostatic designs, is shown by its performance when delivering a 1kHz square wave into an eight-ohm resistor paralleled with a 2μF capacitor. That performance was outstandingly good, with the initial overshoot being less than one-quarter wave height, and the small amount of resultant ringing being damped within five cycles. This amplifier will be completely stable into any loudspeaker. We rather hope that this test report gives the average non-technical reader an appreciation of just how well this amplifier performed on test bench, but we suspect that ultimately it will be only those readers with a degree in electrical engineering who will truly appreciate the outstandingly high levels of performance delivered by Halcro’s Eclipse Stereo. It is a truly mind-bogglingly good amplifier!Ralph-Beyer puts up 20, Sacred Heart defeats Manhattanville 100-60
