Shunyata Research Everest 8000

Shunyata Research’s Everest 8000 energy distributor is ideally designed to work in lock-step with the corporate’s Omega XC energy twine. But we’ll save the pythonesque (as in ‘like a python’ and never ‘My hovercraft is stuffed with eels’) energy twine for a later date; the conquest of Everest is tough sufficient for one difficulty!

Shunyata Research’s designmeister basic Caelin Gabriel has a really explicit set of expertise. Skills he acquired over a really lengthy profession. Skills that make him a nightmare for noise. When Gabriel stopped designing [REDACTED] and [REDACTED] [REDACTED] for the [REDACTED], he turned his consideration to civilian life. His uniquely well-engineered merchandise turned seen by document producers (delivering cleaner energy to decrease noise, thereby making the recording extra exact and your music sound higher) and cardiologists (delivering clear energy to decrease noise, thereby making medical imaging extra exact and sufferers extra prone to survive). At the identical time, Shunyata Research was constructing a commanding repute as audio’s chief noise-buster.

Peak efficiency

As the identify suggests, the Everest 8000 is the height of Shunyata Research’s line. It’s a synthesis and distillation of all one of the best bits of what has gone earlier than. Sometimes, this implies including extra of the identical; for instance, there’s 3 times the quantity of the corporate’s patented QR/BB modules that act like an influence reservoir, in comparison with the already wonderful Denali 6000/T examined in difficulty 162. Others have been considerably improved, such because the CCI (Component to Component Isolation) combo of zoning and filtration, the monolithic development of the design, the usage of the corporate’s patented ArNi VTX ‘digital hole tube’ wiring all through (even within the bus connectors).

It’s very straightforward to get wrapped up within the expertise and patents, however they’re all directed towards two long-standing Shunyata Research targets. The first is a recognition is that quite a lot of what we take into consideration energy is incorrect; we predict these energy ‘nasties’ come from the miles of cable main as much as the system, however in reality, Shunyata Research argues the culprits are the system itself as every energy provide in your system generates its noise. By recognising that noise goes each methods and the extra vital method to deal with that is to restrict the air pollution of 1 energy provide on one other, Shunyata takes the highway much less travelled in audio, and the Everest 8000 is maybe the best proof of idea you’ll hear on the topic.

Instant energy

The different massive concern is to make sure there’s sufficient instantaneous AC energy on faucet for a system. This is an issue that plagues energy conditioners and distributors; sure, the sign is cleaner, and readability is improved consequently, but when it comes on the expense of the dynamic vary and rhythmic ‘bounce’ of a system, for a lot of it’s too massive a compromise. This is why many audiophiles eschew the advantages of an influence conditioner or distributor, even when the necessity is critical. In equity, it is a drawback that almost all energy firms are addressing.

Still, few have ‘nailed it’ like Shunyata Research; the corporate has developed its measurement protocol to check what it calls DTCD (Dynamic Transient Current Delivery) and applies the measurement system to the whole lot from plugs to entire units just like the Everest 8000. The internet result’s units that depart the dynamic vary solely uncompromised, however that will depend on the use case. When it involves the Everest 8000, that use case is the entire of audio! That could be overkill if you’re utilizing a relatively small system with comparatively small loudspeakers that don’t ship huge dynamic swings. Still, the Everest 8000 provides advantages over and above that to justify its use in high-performance metropolitan programs.

Why You Can’t Have Nice Things!

Shunyata Research’s Everest 8000 comes provided in a variety of energy connection choices, to swimsuit US, EU, UK, Asia and Australian plug programs. If you might be studying this from the US, the Everest 8000 features a determine of eight ‘Cable Cradles’ that every maintain a pair of energy cords in place. UK plugs are bigger than US ones, and such strain-relief holders aren’t obtainable right here. The sockets should be angled as a result of most UK plugs have pins at 90° to the cable.

And ‘it doesn’t swimsuit right-angled plugs for the fashion-conscious’ is the closest you’ll get to a criticism of the Shunyata Research Everest 8000. It’s a outstanding performer in so some ways, way more so than the clichéd ‘reduces the noise flooring’ epithet that’s utilized to each energy conditioner and distributor, ever. Yes, it does that, however it additionally provides the audio electronics permission to ship sound as supposed. Individual notes have a extra clearly outlined ‘house’ round them, each when it comes to dimensionality but additionally in assault, decay, and launch. You hear probably the most refined of reverb tails (whether or not utilized naturally, electronically, or digitally… and you may typically hear the distinction in small-scale recordings).

Further into the combination

So far, so ‘audiophile’. We love a little bit of extra ‘microdynamic shading’ and the power to achieve ever additional into the combination for added hard-to-find particulars. And if the Shunyata Research Everest 8000 did that and that alone, it could be deserving of excessive reward. But there’s extra. Stopping all these energy provides from clashing with each other makes them get out of the best way of the sound in some stunning methods. Bass traces aren’t simply cleaner. They are funkier and extra menacing when (and solely when) required. You hear extra of the physique of the instrument and the participant behind that instrument too. This creates a extra lithe and pure efficiency. Even when these devices are digital, you get extra sense of musical order and verve.

I’ve lengthy performed the get-out card with energy conditioners and distributors; I reside in London! Houses polluting the mains and radio frequency environments encompass me. Your Mileage May Vary. But no such weasel phrases are wanted with the Shunyata Research Everest 8000 energy distributor. It makes your system sound higher irrespective of the system and no matter the place you reside. It’s a game-raiser and a game-changer in a single. To quote a tagline from a widely known UK provider of double-glazed home windows “Fit one of the best: Everest!”

Chord Company GroundARAY

When you look at Chord Company, you tend to think about cables… largely because for decades the company has focused almost exclusively on digital and analogue interconnects, power cords and loudspeaker cables. But as an example of just how far Chord Company has come in recent months, the GroundARAY line of noise reduction devices is an entirely new venture for the company. OK, so Chord Company isn’t the first brand to toy with the concept of parallel grounding as overall noise reduction – there are devices from Tripoint, Entreq, CAD, Nordost and more that run along the same lines – but GroundARAY arguably makes the concept considerably more practical!

Going to Ground

Where most of the aforementioned grounding systems rely on a standalone box that connects to spare connectors on a piece of electronics, GroundARAY is a small, cylindrical per-unit device that plugs into the back panel of your electronic device. Each one costs the same £550 (because they are effectively the same grounding device with a different termination).

GroundARAY is a 10cm long aluminium tube with the words ‘Chord GroundARAY’ laser etched along the side and Chord’s logo on its end. The dealer demo pack – with five of them in a black box – looks like the McGuffin in a Mission Impossible movie. In systems where shelf space is at a premium, bringing the grounding solution to the component is less problematic than devoting a whole shelf to an earthing box. Just remember you need at least 10cm behind the product.

Chord Company GroundARAY

Pragmatically speaking, that’s a bonus to GroundARAY that no audio reviewer will ever fully understand; it flies under the radar. A parallel grounding system is very noticeable when you add it; there are boxes and wires everywhere, which are all too easy to spot by non-audiophiles. These can do their stuff, safe in the knowledge that you don’t have to justify their existence. Whether that justification is familiar scrutiny or peer pressure, GroundARAY’s ‘behind the product invisibility’ is a boon.

The ‘secret sauce’ inside the GroundARAY remains secret but is said to be a series of absorption devices, using materials chosen for the specific task. This provides a low-impedance pathway for high-frequency noise, wicking away noise from the signal ground of the device to which the GroundARAY is connected. Were it not that it sounds like Gothic horror, GroundARAY is like a little tube of deadness for your audio system, and the more products that receive the GroundARAY treatment, the more the effect becomes noticeable.

How it works is simple. Borrow a dealer demo box. Listen to your system without them. Put one in a spare BNC, XLR, or RJ45 connector on your DAC or streamer. Listen again. Then do the same in an RCA or XLR socket in your amplifier. Listen a third time. Then whip them all out and give your system a final confirmatory listen with all the GroundARAYs taken out of the loop. Repeat the whole process a second time because you can’t quite believe what you heard the first time. When you hand back the demo box, you find your credit card has accidentally fallen into the dealer’s card reading machine and, well, while it’s there, you might as well order a few.

Grounded in sound

Given Chord Company’s suggestion that these are ‘noise reduction’ devices, the logical place to go looking for sonic differences would be in the noise floor, and yes, those silences are some of the most silent silences I’ve never heard. But that’s only the start of the story; what GroundARAY is so adept at controlling is noise in the high frequencies. This makes audio electronics – especially digital audio electronics and in particular streaming devices – sound less gritty, grainy, hashy and harsh. The sound of almost any instrument loses a lot of that electronicky sheen that has so often been the reason why people still shun digital in favour of analogue devices like record decks. That analogue-like purity of tone and clarity of tonal colour is better resolved with the addition of the GroundARAY.

Of course, this is most telling with female vocals – Joyce DiDonato’s pure mezzo-soprano tone and her coloratura vocal talents benefit greatly from the GroundARAY treatment – but perhaps what’s most surprising is just how much it makes every recording sound that bit more like the real deal. Graunching guitars snap into sharp focus while sounding powerful and loud.

Recordings made in small clubs sound atmospheric to the point where you can almost feel your clothes saturated with cigarette smoke. Meanwhile concerts in large church halls and concert halls ‘scale’ easier to simulate that large soundstage. It doesn’t matter the size of the system; I played all this through a pair of KEF LS50 Meta, and the resolution of space and size was still present.

Ground around

Move from one GroundARAY to multiple, and the effect increases significantly. It’s not an exponential increase; more improvements in air and space around the instruments. But it is easy to hear and universally positive. As stated earlier, the demo devices don’t need to spend much time out of the box before you are won over.

The joy of multiple GroundARAYs is in the way it fills in the rest of the listening experience. This varies from person to person, but, if you like what one GroundARAY does to your personal choice of music, more of them expand your musical options. The process of making treble and midrange sound more like they do when you are at a live event is a heady one, and the more GroundARAY you bring to the party, the more of a party it gets. Just without the hangover the next day.

Chord Company GroundARAY

I still maintain the first date in your GroundARAY relationship is with digital audio, but that does come with a caveat. I think there’s a relationship between the noise these devices are trying to cancel and switch mode power supplies. If you are using an amplifier that relies on switch-mode power, GroundARAY’s impact on the sound is more significant. This might also explain why the GroundARAY works so well with digital devices as they almost universally come with switch-mode juice boxes.

There’s one last point; does GroundARAY play nice with the other grounding devices? I’m slightly limited here to a sample of one (the Nordost QKore), but I’m happy to report that they both work well together and complement one another rather than double up (or worse, cancel out) their effects. QKore acts more on soundstage width, bass definition and noise floor reduction, with some benefits in higher frequency performance, whereas GroundARAY is more about making those higher frequencies as clean as possible and extending that naturalness and clarity down the frequency range and out into the soundstage. And, of course, reducing the noise floor.

You’re Grounded!

As with all grounding devices, the system and environment play their part. We live in a soup of Wi-Fi, and our power lines sing to the tune of switch-mode power supplies on everything from phone chargers to computers, but the degree of impact of those things does vary; if you are living cheek-by-jowl in the big city, those problems are more directly noticeable than if you are miles from your nearest neighbour. Similarly, a system that remains solely LP-oriented and the nearest it gets to modernity is a power-on LED might not hear so profound a difference from GroundARAY. All I can say is in West London with a system that has a streamer. The results were compelling.

The biggest problem is perhaps the bitterest pill of all; supply. The reason we took so long in getting this next generation of Chord Company’s products is not through some angry staring out contest between us; it was that almost everyone who borrows a dealer Demo kit ends up buying at least one GroundARAY and the orders have stacked up. After that home demonstration, you might find yourself on a waiting list for your shiny tubes of pleasure. And that’s frustrating because once you hear what Chord Company’s GroundARAY does, you want it. Now!

2022 Golden Ear: Shunyata Research Everest 8000 Power Distributor

Shunyata Research Everest 8000 Power Distributor

$8995

I have had the pleasure of using the Everest 8000 power conditioner—I mean, power distributor, as Shunyata calls it—for about a year, and the more I’ve used it the more it has impressed me. When paired with Shunyata’s Omega XC power cord ($7000), which is pretty much how most people deploy the Everest, my system makes music sound both more dynamically alive and more at ease. Because the noise floor is lowered so dramatically, greater contrasts in dynamic and timbral shadings allow for a more complete rendering of recordings. Imaging and soundstaging are also more three-dimensional and lifelike. Unlike many power conditioners that can inhibit power delivery, the Everest has a patented power-reservoir technology (called QR/BB) that delivers extra power on demand. Shunyata deploys several other unique technologies, but limited space does not allow for a complete accounting. Build-quality is first rate, and the form factor (an elongated truncated-pyramid shape), equipped with “cradles” to support the cable plugs, makes it easy to use. I believe other reviewers have also given the Everest 8000 awards, including a Golden Ear Award by Robert Harley in 2020. It is so good that I must join the chorus of those who have already praised it. An easy GEA this year, too.

Quiescent Apex 40 coupler and Peak loudspeaker module

Products that aim to mitigate the sonic damage being done to audio reproduction by electromagnetic and radio frequency interference are common. Not least because the latter is a higher frequency version of the former. However, there is a third corrupting influence that is less frequently addressed. It is microphony. Quiescent is one of the few brands attempting to reduce EMI, RFI and microphony.

If we leave aside micro-tremors from the earth’s crust and from traffic, microphony in our audio systems has the same primary source; the speakers. The acoustic energy from them modulates ambient air pressure against our eardrums, but it also vibrates our audio system too. Inside most speaker cabinets, the crossover is bombarded by energy from the rear of the speaker drivers. Meanwhile circuit boards in system components such as amplifiers are effectively palpated by the modulated air in the room.

Energy conversion

Those who paid attention at school will recall that physical energy applied to a conducting material is converted to electrical energy. During normal playback, our systems are processing not just the musical signal that we want to hear but, electrical artefacts that we don’t want to hear. These travel back down the speaker cables to the amplifier, and propagate from discrete components such as capacitors in system separates. They become particularly audible when contending fundamentals or harmonics beat against each other to produce intermodulation distortion, typically heard as ringing.

Even if our audio system is powered through a filter or regenerator, and even if we turn off everything electrical in the house and listen through headphones, we still cannot escape radiated electrical energy and microphony. Audio separates, in particular digital devices, and some discrete components too, are themselves active emitters even when simply passing an audio signal. Once EMI, RFI and microphony have entered the signal chain our costly wires simply perform as conduits for the unwanted noise.

Quiescent has been ploughing something of a lone furrow in its focus on EMI, RFI and microphony mitigation, and in particular on both prevention and removal. The company’s approach is two-part: speaker, interconnect and mains cable designs that resist mechanical excitation and which absorb EMI/RFI, plus passive devices — the company calls them Couplers and Modules — that drain microphony, EMI and RFI. Quiescent is patenting globally the technology used in a new generation of Couplers and Modules, and invited this publication to be the first to try them.

The Apex Speaker Module is a block of black anodised aluminium, machined from billet, with no parallel faces and an acoustically disruptive milled pattern on the outside. It is about the size of a house brick, but weighs rather more at some 4.5 kg. Two continuous lengths of solid silver conductor wire run internally, starting at a pair of silver WBT binding posts and emerging at the other end as a length of captive speaker cable terminated in silver WBT bananas or spades. The first generation Module clamps the naked conductors between two halves of a multi-directional, multi-length labyrinth formed of ceramic. Designed to present a virtual black hole to acoustic energy, the labyrinth prevents transmission either from the speaker to the amplifier or vice versa. The module also contains a passive electrical network to burn off radiated RFI.

Sceptical in the extreme

I tried this early version of the Module in 2018, sceptical in the extreme, but in my system, with two types of amplification and three different speakers, the noise floor was lowered, tonal density and timing cues were enhanced, dynamic energy increased and sound-staging improved. I bought the review pair and for over two years they were a key element in my system, allowing me to hear more deeply into recordings, and to discern more clearly how review kit performed.

Quiescent’s revised Peak Speaker Module has the same form-factor and operational principle as before, but the labyrinth is now made from a composite of granite, ceramic and a high-carbon polymer, the latter material being the subject of the in-process patenting. The company is opaque about the ratios of the three elements, and over what bandwidth the new Module works, except to assert that it is effective on microphony over a wider range than before, and that the carbon polymer increases the bandwidth over which unwanted electro-magnetic energy is absorbed.

The new Apex 40 Couplers are not footers or supports as we might understand the terms, but 3D printed shallow boxes, overall a little less than the size of two packets of playing cards laid side by side. Like the Modules their exterior is irregular with a deep acoustically disruptive pattern. They contain the same tri-material and a passive RFI absorbing network. A sharply pointed electrode on top allows the Couplers to drain acoustic vibration that would otherwise cause microphony, and to terminate radiated electrical energy.

Quiescent Peak Speaker Module

Meanwhile, the Peak Speaker Modules were compared back-to-back with the previous model in my review system, placed between a Bryston 4B Cubed stereo amplifier and PMC MB2se speakers. They brought a far-from-subtle further lowering of the noise floor, the increase in dynamic headroom partnered by greater tonal density, and better focused spatial detail. Improved intermodulation suppression tamed piano recordings that had previously been teetering on the edge of offensively bright and ringy, while excessively sibilant voices were calmed. Bass weight and definition also increased – a finding that Quiescent says results from even more unwanted artefacts being stripped from the signal chain leaving the amplification with less work to do.

The company says the Apex Couplers should be placed under a component either side of the power supply with the third opposing, like a tripod. A firm press from above on the review system DAC enabled the Couplers to make electrical contact with the chassis, and there was an immediate reduction in background hash, stridency and hissy sibilance.

More. Better.

Further sets of Couplers were then added in turn under other components. The sonic gains were cumulative, particularly striking with the CD transport, DAC, pre-amplifier and phono stage, slightly less so, but still very worthwhile, with the power amplifier and turntable power supply.

Fully equipped with Couplers and the Speaker Modules, the review system, no slouch before, was transformed in every dimension, delivering greater dynamic agility and power, tonal density and timing cues; in all posting a quite remarkable cumulative uplift in performance that most listeners familiar with the system put in the order of 50%.

Improvements in perceived timing were particularly noted, there being a greater immediacy and drive that made complex, multilayered and polyrhythmic programme easier to listen to and appreciate. It reminded me of my ‘yikes, this is closer to live’ epiphany on first hearing a pair of Kii Three speakers, phase-correct right across the audio band and thus able to deliver more of the you-are-there experience. There’s no suggestion of equivalence here; but by doing what they do do, the Modules and Couplers brought about a very obvious reduction in the degree of damage being done to phase by the review system’s non-DSP disk-to-speaker audio chain.

The elephant in the room is of course cost. Using the Quiescent products in even a simple system is not for the faint of heart or shallow of wallet. It would take particular bravery to put a pair of £4,500 Modules with £1,000 floor standing speakers. Would the result be at least £5,500 worth of sonic value?

Cost/benefit

However, in the context of the total RRP of the review system, the cost/benefit ratio of the Quiescent products can, in my view, be easily be justified; does it need to be said that a 50% gain in sonic quality is not trivial?

The most likely explanation for Quiescent’s shyness over measurements is not that it hasn’t done any — come on, of course it has — but, probably correctly, the company understands that expensive products like these are not bought by customers on the basis of metrics, but of audition. And that is the market model that Quiescent is now returning to after a three year dalliance with direct selling. Dealers who will carry demo stock and facilitate no-risk in-home evaluation are being appointed across the UK.

Audience forte V8 Power and forte f3 powerChord

Like me, you’re probably running short of outlets in your listening room. Where’d they all go? Looking back it was a lot simpler when source components were limited to a turntable or CD player. A couple of plugs, a preamp, an amp, and you were good to go. Digital media introduced a whole new level of demand for power outlets. From wireless modems, network routers, wall-wart plugin power supplies, computers, servers, DACs…arrgh! Sure, you can grab a scary-cheap plastic power strip at a big box store—it’s a free country. Or you can be a little more discriminating and opt for …

Nordost QRT QPoint and QRT QSource Resonance Synchronizer

Nordost QRT QPoint and QRT QSource Resonance Synchronizer

About a year ago, I first heard the Nordost QKore system—a passive approach to grounding that proved to be extremely effective. Even though my stereo system was running off an Equitech transformer and special Cardas runs of wire to hospital-grade outlets, it turned out that the noise floor could be taken down another notch. The benefits—a silkier presentation and blacker backgrounds—were immediately audible. To my surprise, Nordost hasn’t stopped there. Nordost representative Michael Taylor indicated to me that the company was introducing a new and separate product to try and further improve playback sound. I first got a chance to …

Computer Audio Design Ground Control-Reference grounding box

Computer Audio Design Ground Control-Reference grounding box

When it comes to audio, it seems to be hard to get majority agreement on anything, but the one exception to that rule is the broad concept that less is (generally speaking) more. But even here you can run into trouble once you start drilling down as far as cause and effect. Just take system grounding as an example: less noise – definitely good: the proliferation of separate ground boxes? Suddenly, customers are not so sure – especially once they start to factor cost into the equation… Not so long ago, system grounding was the brave new frontier, virgin territory …

As a reviewer I have the opportunity to audition world-class equipment and accessories, as well as real-world gear. The world-class, skies-the-limit stuff is always a treat. Who wouldn’t enjoy an extended Ferrari test drive, or a month with a Bentley Turbo in his garage? But reviewing real-world gear provides a sense of satisfaction and simple pleasure. At $3600, the Clarus Concerto falls firmly into the category of real-world equipment (at least in the real world of audiophiles). It also falls into a category filled with competition.

Shunyata Research Hydra Delta D6 Power Distributor and Venom NR and V14 Digital Power Cables

You can find a report on my first hands-on encounter with Shunyata Research cable and power products in Issue 239. Back then I was reviewing the company’s most basic setup—a starter kit for first-time upgraders—the Venom PS8 power distributor, Venom Defender chassis-free plug-and-play power conditioner, and Venom HC power cords. For under $1300 its performance and resolution surprised no one more than me. Truth be told, I’ve had a conflicted past relative to this segment of the market—its claims and costs. It’s fair to say that I considered myself reluctant, but persuadable. However, Shunyata’s Venom system refined my system’s overall …
