Blackbody v.2: I've never tested anything like it.

May, 2023, author: Dawid Grzyb
"If you've gone this far yet still are the curious type keen to take the red pill and personally investigate that rabbit hole, the company LessLoss will show you how deep it goes."

"I find this entire noise-killing lot highly efficacious.Today's Blackbody v2 is unlike any other LessLoss product I've sampled in the past."

"I've never tested anything like it."

"LessLoss' track record among customers and press is solid to say the least."

"I was ready for subtle differences revealed gradually within hours if not days, but that wasn't the case. Not only this product did something, but it did that pretty much right away and in fashion obvious enough that I didn't have to second guess what it was."

"The entire view grew a touch more anchored and denser in both cases, but higher humidity was the most obvious change. The air in-between key sound sources felt rich and fragrant just like before a storm. The overall vibe was less dry and chiseled."

"Instrumental and vocal shapes struck me as more moist and bloomier than before, while their outlines became somewhat thicker."

"Sound audibly leaned towards the extra color, boldness and aroma rather than twitchiness, sparks, elasticity and high contrast. Increased relaxation and less prickly incisiveness followed."

"Considering all this, Blackbody V2 was groomed to fit the usual LessLoss noise-killing profile indeed, so enjoyably familiar."

"Vast majority of setups will enjoy them."

"A single such unit absorbs very little radiation yet its action already registered. Two were more audible though not as much as five. Whatever it is that they do, my ears tell me that it stacks. Now I'm wondering what several dozens of these objects would've delivered."

"It's also worth knowing that daisy-chaining them is the best use case scenario. Then the main Blackbody v2 effect becomes noticeably more pronounced without further trimming dynamics. At least I haven't detected any changes in this regard."

"It's clearly meant for those who have their audio kits fully sorted and evaluate such products with their ears. For what it's worth, three springs back Blackbody v2 worked for Srajan and now it did for me."

Blackground 10x Power Base: "Very obvious and significant" "All roses no thorns"

January, 2023, author: Srajan Ebaen
"What the BlackGround claims to do no other audio device I'm familiar with addresses."

"we might even call the BlackGround an awareness-raising tool."

"The effect takes a while to kick in, then more time to saturate fully. It's nothing like a light switch. But neither is it 500-hour break-in by which time we wouldn't have a clue. We're talking perhaps a day."

"impossible to mistake or overlook."

"After a full day of undisturbed presence, the BlackGround caused a wholesale removal of this treble dirt."

"Think satin sheets and silk pyjamas, not dry saw dust and brittle straw. To my ears, this shift in tonality/lighting was accompanied by a mellower more leisurely or relaxed mien. Energetic forwardness laid back, sharpness morphed to viscosity."

"On my table of musical qualities, the lazy Susan turned rhythmic tension to the far side to have me face the beauty of tone instead. Textures felt ultra suede or chenille, not spiky or metallic."

"sweetness which arises in lieu of the former metallic rust or splashiness"

"The BlackGround's before/after was dead obvious."

"Listeners familiar with their systems need only give the LessLoss BlackGround 24 hours then hit 'play'. They'll be at a complete loss to explain it but will most certainly hear it."

"My gut instinct predicts that listeners of predominantly acoustic libraries and particularly classical in all its forms will absolutely love it."

"How did Sven Boenicke describe his reaction? "It's that energy shift away from the glare and garbage especially in the top end into the organic, colorful and beautiful; the brown, red, orange and golden colors. That's what I so love. Plus it does something on the reach-out and communication level which is magic." I reckon that we very much heard the same thing. I also think that I get what Sven calls the reach-out communication factor. I experienced it as that more fluid viscous quality."

"This shift isn't barely audible like changing a DAC's digital filter. It's a very significant reset from an approach which cynics and cackling forum hyenas might insist couldn't possibly work."

"you'll introduce recognizable elements of the triode aesthetic."

"upsetting my balance enough simply reiterates how potent this stuff is."

"all roses no thorns."

"a 24-hour come-on-song period will have changed your tone textures and related perceptions in dead-obvious ways."

"the BlackGround works, period."

"the effect's particulars mirror prior LessLoss inventions like the Firewall for Loudspeakers and AC line conditioner but at higher potency."

"the effect is very obvious and significant."

"the full effect takes time to saturate and desaturate"

"In closing, the LessLoss BlackGround is a bona fide invention."

"Listeners who appreciate the sonic changes described will do themselves a serious disservice if they shun this device"

"Reviewers could worry over having visiting gear bask in the BlackGround's glow to misappropriate praise."

"Like magic. The BlackGround 10x Power Base is Voodoo supreme."

December, 2022, author: Rick Becker
"There was more inner detail, not because notes were more resolved, but because a lot of noise had been eliminated."

"Like magic, the music got better in all the same ways it had the previous night, confirming what Louis had initially alerted me about. It is not a component you can A/B test rapidly because the change does not happen like flipping a light switch. But give it an hour to settle in and the effect is very obvious... and very welcome."

"The music continued to improve with more inner detail emerging, particularly with many of the obscure lyrics. I was understanding a lot more words and hearing a lot more tonality and musical nuance than ever before, particularly in the bass."

"I was able to hear more tonal color (timbre) so the music was a lot more interesting."

"And WOW! Sound quality jumped."

"You don't have to be an experienced Golden Ear audiophile to recognize these, either."

"A lot of noise that you probably didn't realize was present, disappears – across the board, from sub-bass through treble and probably into super-tweeter territory."

"Musical qualities become more evident. Things like improved resolution, attack & decay, tonal color, timbre, and dynamic shading."

"Softer tones become more evident. You can better hear the notes fade away into silence. You might think your hearing has improved."

"...major revelation was the sense of physical space. The soundscape was considerably deeper."

"Instruments, singers, and orchestra sections were more firmly positioned."

"The air of the recording venue was cleaner and more transparent. Subtle room tone cues were more evident, creating an acoustical environment in my room that was profoundly more real. It was this improvement in the way stereo tricks our brain into thinking we are hearing live music that makes the BlackGround 10X so dramatically appealing."

"If you pretty much loved your system before, you will love it even more, now."

"It was relaxing in that I was using less mental energy to figure out the lyrics, locate musicians in the soundscape, and sort out the interplay of musicians or sections of an orchestra. But it did not lull me to sleep or disinterest me in the music. On the contrary, the bouquet of musical qualities drew me deeper into the performances leaving me with energy left over to explore the music at higher emotional and intellectual levels, rather than struggling to just hear the music."

"It wasn't just occasional moments it was everything I listened to! I grew up with rock 'n roll, but with the BlackGround, I was surprised at how intrigued and mesmerized I became with classical music."

"Do you need footers? The BlackGround 10X is such a huge leap forward that I expect you can live happily without them."

"The big plus in using the BlackBody with the tube amps was the enhanced emotional connection with the music. I was compelled to listen more actively. This was an unexpected and welcomed surprise as this is why I've been a tube fan from the beginning. The music gets so real you can almost hear the performers sweat."

"...higher level of realism on well-recorded tracks, leading to a greater level of involvement with the music."

"...more of a sense of space around the instruments, and a more 3-dimensional sound stage. I find that I am paying more attention to the music and less to the quality of the reproduction."

"I get a better sense of being in a large concert hall."

"It sounded more like real musicians playing music right in his room than most of the rigs I've ever heard in my life."

"As I left his dedicated listening room with the BlackGround in hand I felt like the Grinch stealing Christmas."

"Audiophiles cover a broad spectrum of wealth. But cost is not the same as value. Whatever your financial circumstance, the BlackGround 10X addresses an issue that other components are not designed to handle. The benefit gained from the BlackGround 10X is unlikely to become obsolete."

"I can imagine spending anywhere from $10,000 to $100,000 without any guarantee of equaling the transparency and musicality the BlackGround 10X provides. Maybe even more money than that."

"Most of the rooms that I hear at shows that sound as good or better than mine does when equipped with the BlackGround 10X are priced above $100,000 and even far above that. Many that are priced at several hundred thousand dollars have not sounded as close to live music."

"I strongly believe it will bring a greater sense of live music to even the most expensive systems."

"Call it voodoo if you wish, but it is a breakthrough technology that supplements and goes far beyond existing power conditioners. I have heard what it can do and I am buying a production version to replace the prototype."

"Over the years I have learned that one of the best ways to compete with components that cost way more than I can afford is with voodoo. The BlackGround 10X is voodoo supreme."

LessLoss Power Distributor: "I saw no downsides ... showed a middle finger to that guesswork."

December, 2022, author: Dawid Grzyb
"...produced extra bass that dug deeper and scored more points on authority, while the resulting stronger, more controlled, overall feel morphed each bass-intense song into a noticeably more massive, yet at the same time agile version of itself."

"The entire landscape [...] also struck me as a fair bit inkier, more calm and spatially sorted. Tonal saturation went up to make fuller, fruitier sound, which seemed as articulated and brimming with details as ever."

"I saw no downsides to these changes, only improvements."

"The conclusion here is twofold. The efficacy of Firewalls inside these products truly piles up. These modules also make a noticeable difference in spite of all the extra contact points and wires along the road. Because of these mechanical obstacles I thought that the two wooden outlets used as described could've either crippled sound quality, or made no difference at all. Their Firewall squad, however, showed a middle finger to that guesswork. Live and learn, as they say."

"...pushed the performance envelope several notches further in the familiar direction and that made quite the difference."

"It enhanced contrasts, extended the color palette, injected extra blackness into the background and unlocked greater firmness and heft."

"will audibly improve every setup I can imagine"

October, 2022, author: Dawid Grzyb
"...deep background blackness upon which instrumental moisture, resolution and sensation of the aural space itself blossomed."

"...not only removes excess fuzz, bloom, grain and veil, but it also accelerates sonic MO"

"...makes them more open, vigorous and alive."

"...juicy, texturally generous, propulsive, informational and spatially unrestricted at the same time."

"There's no question that the LessLoss' inherently fetching dark round bloomy anchored sound makes a nice first focal point to stop at and appreciate. Once that early sensation settles in however, the product introduces itself as a resolution fiend capable of casting enormously large landscapes busy with easily served details and pinpoint accurate finely outlined sound sources."

"The Lithuanian's ability to behave this velvety, smooth, atmospheric, aurally gifted, elastic and keen on extracting tiniest dust particles is highly admirable in my book."

"... superbly balanced and free from any obvious trade-offs. As such the LessLoss won't steer a setup's general gestalt in any particular direction. Instead it'll gladly and gracefully elevate what's already there."

"The LessLoss renders music as substantially more flowing and digestible than before, which I see as its primary attractor and most critical task."

"This highly universal and accomplished product will audibly improve every setup I can imagine no matter its core flavor. I also think that it has what it takes to hold its ground even against similar opponents higher up in the pricing hierarchy."

"Considering the LessLoss' price, artisanal execution, usefulness, overall sonic performance and its sheer potency, I've found no evidence that'd work against it."

"It's up there with the very best power distributors I've sampled and the most affordable of them all by far."

"This is a fully mature, elegantly voiced effort built upon very advanced noise-rejecting tech that proved highly efficacious."

"This really is powerful stuff."

August, 2022, author: Srajan Ebaen
"An unusually tacit sensation of overall calming – a German video reviewer calls it peace – which for me presents foremost as musical relaxation."

"To many it suggests a more analog than digital gestalt. Particularly the higher frequencies show a removal of metallic grit. The low frequencies tend to become more intelligible and articulate which also affects the midband."

"Finally there's a keen sense of more extended reverb"

"US sockets showed proper sportsmanship by welcoming my AC plugs with the death grip of a professional arm wrestler."

"Sonically the noise-cancelling C-Marc hookup wiring, passive inline Firewall noise filter and the firm's accelerated aging process dubbed Entropic all working inside the same box had a definitive effect versus our usual Furutech GTP 2D NCF. In essence the sound got both faster and fuller."

"Here fuller meant deeper color saturation plus the elasticity a honey drop shows as it detaches from a spoon in a slow-motion video. That visualizes lengthier decays. Meanwhile faster meant upped transient brio. Percussive and staccato elements still peeled out sharply from legato passages."

"Incisive sounds seemed to crack and snap harder, indolent sounds definitely were lazier. The upshot was greater textural bandwidth. The end stops of hard and soft had moved farther apart. Along their axis I heard more variety and difference."

"LessLoss vs Furutech passive wasn't about split hairs or spilt milk. The difference was very easy to hear."

"In my mind there's no question. Despite being a passive device, this new LessLoss Power Distributor is a very active sonic influencer. It shaves off edge and grit like successively finer sandpaper. That installs smoothness and prettiness. It also tames down shine and brilliance with a new textural softness that's a bit darker. Ratcheted musical tension relaxes for greater calmness."

"This really is powerful stuff."

"A real eye-opener. Fantastic."

April, 2022, author: Claus Volke

"You can really hear the effect that it has on loudspeakers immediately."

"I have tried the firewalls with tube amps, and solid state amps. I tried them with full range speakers, high efficiency speakers, horn-based speakers, classical dynamical two and three way speakers and with my Rogers LS 3/5. The effect of the Firewalls is always perceptible."

"There's no question about whether this might be self-delusion or wishful thinking."

"You hear the effects immediately."

"The music gains a peacefulness without becoming damped."

"It's not as though you're sitting in a room and try to damp it out with curtains, damping material, that sort of thing."

"On the contrary, you gain clarity through peacefulness."

"Bass is for sure more precise and I'd say springy."

"It's extremely audible that acoustic bass becomes more differentiated, and extremely more colorful and impactful."

"This is not something that is added to the signal, but it really comes from the absence of distorting impulses. This is how I perceive it audibly, because it was immediately noticeable."

"This is also noticeable in the midrange. It sounds more analogue."

"It sounds more sonorous, without at the same time losing any differentiation between lows and highs."

"So really it's a focussing effect which allows you to hear more than you could hear before."

"So for instance listening to a soprano voice, I get the feeling that that's really a human voice I'm listening to."

"This is by no means wishful thinking. For certain it is not."

"Especially with acoustic instruments, the differentiation increases drastically."

"So let's say, in baroque music, with smaller ensembles, with, say, harpsichord accompaniment, one can really hear the differentiation very well."

"This is all to say that, according to however much noise casts its shadows on the sound, this noise is suddenly removed and it improves the overall resulting performance."

"When you can clearly make out bass and lower mids, this can also have a side-effect that it seems the high frequencies have been lessened, for real musical tones are never made up of just one frequency band. So if we make lower and low-mid frequencies finer, softer, but also more differentiated, this will also seem to influence the high frequencies, as it seems new frequency bands appear."

"Don't worry about the Firewall influencing existing speaker cable influence."

"The Firewall for Loudspeakers don't influence the sound's characteristics."

"And the speaker cables, like I said, their sound characteristic is not influenced, it is merely helped by the lack of negative influence in that the signal is cleaned."

"With speakers the effect is the same. With amps as well. I tried tube amps and transistor amps. The effect is exactly the same. You can still hear all the characteristics of each piece of gear."

"I switched back and forth several times between transistor and tube amps. The Firewall did not influence their individual characteristics."

"Instantly recognizable, obviously better, more colorful bass."

"The changes are definitely there and you can hear them."

"Certainly you should really test these."

"You hear it instantly."

"Is it always a positive change? Yes, I would say so."

"For many, this can be a real eye-opener, especially when you consider your system to already be well balanced and mature, these will take it to the next level. Fantastic."

"Obvious Sonic Benefits"

April, 2022, author: April, 2022, author: Adam LaBarge
"It really works, it does make a difference."

"It was immediately apparent and easy to pick out the sonic impact of the Firewall. The very top-end, as well as transients, were exceptionally clearer and with a slight bit more volume to them. This resulted in the sound stage being more apparent and everything at the cymbal frequency range, or other high frequencies, being exceptionally clearer and much easier to understand. The mid-range, as well as the bass, also sounded cleaner."

"It is as if yet another small layer of the obfuscating film had been removed from the recording."

"I also noted the tail-end of the drum strikes or last vocals on a track, whenever a sound was given time to completely decay, was clearer. The slope of the decaying sound was more sustained and natural sounding, and the lower level tail-end of the sound was easier to hear. Plus, when the decaying sound finally faded so low as to no longer hear it, it did so with just a bit more presence in that final transition from life to death."

"During the music, the high level of detail in the decay was also more noticeable, giving what seems like more "space" between the notes of the music or the vocalizations of the singer. For example, Lenard Cohen's lips smacks were a bit more discernible and his voice, on the whole, sounded less compressed and more fully dimensional."

"Easier picking out and understanding all that is going on."

"obvious sonic benefits"

"bass also sounded faster and more detailed"

"doesn't seem to compromise or obscure the effectiveness of good power cables"

"I have enjoyed the benefits of the Firewall, and like Ken, I think I am going to purchase the C-MARC version, as now that I've heard it, I don't want to take a step backward in performance."
