"The more these modules are in use, the more their effectiveness compounds, specifically backdrop cleanliness, spatial focus and moisture."

"Higher instrumental and vocal hydration, more grounded sound, rounder less chiseled edges, tighter bass, improved clarity, less grain and all virtual shapes rendered more precisely on a background that felt sensibly more pristine."

"Not only do I deem Firewalls very useful with all kinds of speakers, I haven't yet encountered one that wouldn't audibly benefit from such assistance."

"free from any sonic downsides"



"In my system I see LessLoss Firewalls for speakers as necessities rather than accessories."

"Their work may seem mild at first, but disengaging them after a week or two of constant use is plainly painful. Then it hits us how much these small barrels actually contribute, or rather how much is lost upon taking them away."

"Firewalls don't add anything audible to a system's voicing that is not already there in the first place. These aren't tools meant to alter its core flavor. Instead they show how it fares without the well-known byproducts of noise; harshness, sharpness, leanness and grit."

"Bass stripped from noise develops extra heft and fullness alright, but also becomes tighter and more powerful"

"The entire musical image grows larger and more robust, while edginess that causes listening fatigue vanishes. Unsurprisingly, the latest Firewall tailored for headphones follows this exact protocol to a tee. As such it introduces only audible gains."

"More body, less pointy outline edges, less sharpness and less textural gloss, then followed by beefier tighter bass, more pronounced meatier midrange and far superior highs, particularly on decay and smoothness."

"Today's Firewall also greatly boosts the sensation of aural space, so that it feels more breathing, moving and alive."

"The very last instrumental reverbs significantly easier to 'see' and appreciate."

"Clarity is yet again the key word. With cans as resolving as the Susvara, well, this single aspect massively gains on importance. The most interesting thing is that the major quality hike introduced in the process happens alongside the additional provision of substance, textures and body instead of it being in the least decreased in trade as is often the case."

"elevated immediacy, energy, bite and snap"

"I heard primarily smoother and more distinct vocals."



"Sounded more clear and with extra bite to it, as if all its snappy jabs got shorter and more impactful in the process."

"With the LessLoss, the first part struck me as calmer, prettier and all in all fancier, while the energetic outro was noticeably more immediate, muscular and feistier. In other words, the two very distinct parts on that track had their specific quite opposite vibes pronounced better. I found that excellent."

"The Firewall [...] made the entire tune more flowing, still calmer and dreamier."

"Increased smoothness, ease, flow, juiciness and less compressed more distinct instruments. Individual bits on this tune registered as more pronounced sounds, which were again easier to follow and focus on. In effect the entire track registered as a more romantic and sensual version of itself with the LessLoss."

"Noticeable gains on rhythm and swing, as if the main instruments' individual notes were more on point."

"With the Firewall engaged revealed a significantly better grip on bass and less coarse yet fleshier more articulated female vocal."

"Sufficed to keep my ears happy and mark the clear quality bump."

"The Firewall injected more air into the view and dynamically expanded these roars to make them more sensible and instantaneous."

"Voice also struck me as more alive and here, while all the high-pitched sounds registered as quicker, somewhat uplifted, weightier and more shimmery."

"With the Firewall it was less pointy, denser, wilder, more raw, articulated and blunt. Most importantly, the Lithuanian support made a hugely positive difference on this specific song. To my ears the sensation was comparable to listening to it on a floorstander armed with say two small cones, and i.e. Zu Audio DWX armed with one large paper membrane that needs very little power to pump lots of air very effortlessly. The way how such drivers speak the rock language makes them something entirely different on scale, directness and sheer entertainment. The LessLoss simply knew the dialect."

"The bass dug deeper, claps had more snap and body to them, the vocal was more substantial and lifelike and spatial sizing grew noticeably larger. The song felt more intense, enveloping and grander in spite of its somewhat slow-paced rhythm. At that point I had enough data to understand how much the Firewall actually did, and how beneficial it was."

"The Firewall not only supported such repertoire as per the above, but it also allowed me to enjoy it at really loud volume. This was a personal win that I thoroughly appreciated."

"Considering how greatly the LessLoss Firewall elevated my experience with a specimen as universal as these planars, I can't think of any other headphones which wouldn't enjoy such company."

"The tech inside it has been around for years and proved highly effective for many people including yours truly. More importantly, it introduces gains which are very hard to come by elsewhere, especially at a dosage this high and for less coin. Personally I'm very happy that a Firewall device for cans is now a thing and every bit as effective as its awesome speaker siblings."

"the connectors clamp down like pit bulls."

"very pliable."

"Proper cable routing won't require a planning degree."

"sound quality dove still deeper into greater immediacy."

"more luminosity."

"higher charge, energy, enunciation and separation."

"The Stellar cords now shifted my textural needle a few degrees deeper into speed and illumination"

"I was rather surprised"

"greater motility and overall aeration"

"a very particular lit-up directness."

"if money were no issue, these leashes wouldn't return"

"In a high-resolution context, even small reductions in residual system noise can manifest as sonic advances. This particular noise isn't audible per se like a minor ground loop, transformer hum or power-supply surf emitting through a tweeter. Rather it's bat-sphere stuff which intermodulates or 'echoes down' into the audible band. Wherever capable noise killers manage to clear away some of that bat crap, we hear just a bit more micro detail. Nearly invariably that's about recorded space being better illuminated by very low-level reflections between and behind the images. It also moves more subliminal upper harmonics out of the noise floor. That overtone illumination generates more timbral diversity. Individual instruments and singers sound more not less different from each other. Finally there's a sense of flow or breath. That creates continuity or cohesion at the same time that greater resolution sets up more separation. When music rides more obviously on the real breath of singers and woodwinds or the microdynamic bel canto of other instrumentalists emoting with nuance–cellists can be ace at that–we invariably gain persuasiveness."

"Playback feels more human, less mechanical. Compared to my darker heavier thicker residents of less nuance, these were the shades of pastels the visiting Stellar cords played with in my hardware context."

"It gives more insight for less volume. Put differently, there's no need to fight with any obliqueness of darkness and its many manifestations. Just turn more light on.
Not bad for a pair of 'just' power cords, innit?"

"the Stellar range-topper would seem perfect for that first link between wall and power distributor. Now it will benefit all kit which hangs off the outlet expander to multiply the cost/performance ratio and spread around the luv of lower noise and higher resolution."

"songs that I'd heard over a hundred times were giving me goosebumps once again."

"I was off to the races, wanting to hear more and more music as the effect grew stronger over the next few days."

"the effect of the BlackGround for Speakers was very evident."

"the music was more natural sounding."

"it was the genius of the BlackGround that addressed the environmental noise pollution"

"the LessLoss BlackGrounds improve the entire system."

"More transparency, cleaner air, and more distinct placement of instruments on a larger sound stage with noticeably greater depth."

"the female vocalists and instrumental separation were excellent, and the cymbals were highly resolved and shimmering. Everything I played was coming through at the highest level of sound quality I had ever experienced in my system."



"The bottom line here is that you get what you pay for with the Classic being a significant step above the original Prime cable, and the Entropic version taking the sound quality even higher with more stable, unwavering sustained notes, minute inner detail, more subtle tonal color, and tighter bass. Sibilance was more tightly controlled and the clapping of audiences was more realistic."

"The sonic signatures of all three LessLoss cables are the same. But each one does it better when you pay more. You see more deeply into the music. You hear more inner detail. And the musicians are more present in your listening room."

"There is a very positive synergy between the BlackGrounds and the LessLoss power cords"

"I was awestruck."



Buddy Guy was "right there", I proclaimed, pointing dead center just beyond the plane of the speakers. In fact, everyone was "right there" with more transparency and three-dimensionality, more impressive resolution and dynamics."

"I was captivated by the high degree of reality coming from the recorded music and the ease of ignoring the technology, allowing me to just imbibe the music. Instruments or singers up front did not obscure instruments behind them. The monoblock Speaker Bases remove the equipment from the listening equation. Setting cost aside, the monoblock Speaker Bases are the units you want and I implore you not to audition them if you cannot afford them."

"Adding the monoblock Speaker Bases was transformative, bringing FM classical music beyond what I typically experience with CDs. The three-dimensional soundscape, the transparency, and the sense of air in the recording venues of live orchestras were dramatically improved. The resolution in the treble was particularly impressive with violins and cymbals"

"The improvement the monoblock Speaker Bases brought to my FM radio listening was an unexpected bonus. It reinforces Louis' contention that the effect of all the BlackGrounds extends out into the room, affecting not only the adjacent components but also the nearby FM antenna."

"Slam! The bass tightened up immediately and very impressively"

"The timbre brought out by the addition of the stereo Speaker Base raised the sound quality of the $37k QRC-2 speakers close to the flagship of the Acora line, the VRC-1, a truly world-class speaker priced at $218k. I was very impressed. But wait. It gets even better!"



"The bass tightened up even further and there was no degradation of the treble"

"I don't think I can find this much sonic improvement for this kind of money to upgrade what I already own."

"the pair of BlackGround for Speaker 10X monoblocks gives you the biggest acoustic return on investment. Add four speaker cables, one ground wire, and the Classic Entropic Process power cord (or splurge for the new Stellar) and you will have an entire system upgrade that will not become obsolete for less than $10k."

"It may be an 'end game' for your entire rig, leaving you to simply enjoy your music."

"Having worked with all three BlackGrounds, I can assure you the effect is cumulative. Furthermore, LessLoss offers substantial credit if you wish to upgrade from the stereo Speaker Base to the monoblocks. Very nice people."

"When I consider the BlackGround for Speakers elevated the sound quality of my system with $37k speakers up to the level of the best speakers I've heard in the $60k to $100k range, the value skyrockets."

"At the highest level with the monoblock Speaker Bases and the Classic Entropic power cord, the BlackGround for Speakers allowed me to experience greater resolution and transparency that revealed much finer inner detail, a far more colorful tonal palate, and holographic instrumentation far beyond what I thought my real-world system could deliver."



"Increased soundscaping and greater dynamics were also evident due to the lowered noise floor."

"The BlackGround for Speakers helps level the playing field against rigs with outrageously expensive products that only a few can afford."

"They are in a category of their own."

"the BlackGrounds feel like essential standard components. I never imagined I could own a system that could play music at such a high level."
