Press Reviews

"LessLoss Jam Gloves enhance power cable performance, delivering greater transparency, improved resolution, and a more lifelike musical presentation in a reference-level high-fidelity audio system."

"It had been the closest to a live performance that I had achieved in my room, and the magical effect of the Jam Gloves was the principal contributor to this experience."

"Once I achieved the "aha!" experience, the benefit of the Jam Gloves could not be unheard."

"very impressive contributions of resolution and transparency"

"the fine edges of the notes teased the hairs on my body from my legs up through to the back of my neck."

"My power conditioner can be upgraded with a much better power cord for an additional $4500, or the flagship power cord for an additional $8500, but I doubt it would be any better than adding a pair of Jam Gloves for $364 each."

"An electric guitar jam became more highly resolved, revealing individual notes without smearing that were obviously sweeter than before. With more resolution, there was more tonal color in the bass, and more inner detail throughout the audible spectrum."

"You can chase $100,000 speakers, amplifiers, or DACs, and still not come home with something that improves the system you already own like a trio of Jam Gloves for $1100. (That's 1% of the cost of those speakers if you're reading this late at night.)"

"Jam Gloves bring the music even closer to the experience of live music. It took me a while to recognize their contribution, but once I removed them from the system, they were dearly missed, and I could not un-hear the resolution and transparency they brought to the performance."

"No one component, cable, or tweak has brought me to the level I have achieved with the addition of the Jams"

"greater emergence of the information contained in the midrange."

"Voices, reverberations, finer attacks, and certain harmonic reflections seemed less restrained."

"Certain inflections, certain cues, the microdynamics of the consonants, and the relationship with the club environment were easier to follow."

"greater clarity of the overall picture."

"better cleanliness of the edges of sound events."

"The mid-high information seemed more present because it was more separated from the background, and the tonal level was maintained."

"the result remained tonally intact and recognizable, yet more legible."

"The pizzicatos had a slightly sharper contour, the bow maintained its natural grain better, and the voice maintained greater continuity, as if perceived with greater presence and focus."

"greater precision and articulation, with benefits also in terms of speed. With the Stellars, the attacks were a bit more immediate, the decays richer and more reverberant"

"It became easier to distinguish the physical gesture. The bass not only increases in speed: it also maintains fullness and articulation."

"This is an important result, because it takes little to speed up the low frequencies and lose the rest. On the contrary, here the lower registers seem less burdened"



"more legibility in the internal details."

"background appears slightly tidier and environmental information emerges more naturally. It's as if the image weren't redrawn, but rather cleaned up in some critical areas."

"The LessLoss Firewalls for Loudspeakers Stellar Edition aren't accessories that add anything in an obvious or artificial way."

"They don't change the system's voice, they don't shift its tonal balance. Rather, they address that subtle and difficult-to-describe area where residual noise, micro-grains, and small inaccuracies end up limiting the full intelligibility of the musical message."

"In practice, what they do is make the overall picture more readable."

"The mid-high range, after an initial impression of greater clarity and brilliance, stabilizes in a more organic and full form."

"Vocals appear better delineated"

"harmonic details separate more naturally from the background"

"reverbs and ambient aftereffects become easier to follow."

"The low frequencies ... appear fuller, more articulated, and more clearly discernible in their attack and decay."

"The soundstage isn't redrawn, but it gains some fragments of internal order, especially in the perception of small ambient details."

"all this happens without altering the system's character. In a mature, balanced, and benchmark system, this is perhaps the most important result."

"I would recommend auditioning the LessLoss Firewall for Loudspeakers Stellar Edition to a very wide audience, ranging from those with a well-tuned entry-level system to those working with top-tier configurations from the world's leading hi-fi elite. There's always a step up, and these Stellar Firewalls seem designed precisely to point that way."

"Obviously Stellar's res trumped that of my Virtual leashes."

"Recovery of faint harmonics was superior. That gave spatial cues and timbral completeness more data points to paint with."

"Bandwidth of the top three octaves was more informative."

"For an easy takeaway, let's call that aspect as splitting the gap to premium silver. That was unexpected."

"Polished up the top end."

"Warm embodiment of generous never clipped decays."

"Acquired extra lumens"

"Conveys more in-sight"



"Moves a click or two up on the subjective resolution scale."

"All gain no pain."

"It's still rich and elastic—but adds harmonic differentiation and top-down micro resolution that are new."

"There's no sonic fuzz"

"Elevated resolution"

"Absence of nervy aggressive pesticides"

"Pure natural round taste."

"In generic amplifier lore, Stellar is more class A than D."

"It's the best in the LessLoss catalogue, and still a far cry from what equivalent bests demand in the catalogues of Siltech or ZenSati."

"...most refined take yet on passive power conditioning..."

"...sits prominently within the catalog as the most advanced"

"In hand, the device—finished in a satin sheen—unmistakably feels like a costly, premium object."

"bass extends deeper, gains speed, substance, and authority, becoming more anchored, defined, composed, powerful, elastic, and dynamically eager."

"hollowness or boominess that reinforces room chatter is noticeably reduced."

"Vocals shed excess edginess and grain, gaining color, density, smoothness, and articulation"

"The backdrop grows darker, cleaner, more engaging, and richer in nuanced detail"

"The soundstage expands, develops additional layers, and increases in complexity, while all images remain in focus, expressive, and contrasting."

"profoundly effective"

"hardly subtle"

"With it on the job, some aspects I’m about to explain were very well pronounced. Without it, they were either greatly reduced or missing, so the entire musical intake felt different—far less engaging and pleasing to me."

"it made a demonstrable difference without any second thoughts"



"With the Firewall 640x Stellar engaged, each image gained additional heft, moisture, and smoothness."

"every instrument—and even the finest dust particles suspended in space—felt more sensual, organic, and alive."

"While the track accrued atmosphere, anchoring, substance, and fleshiness, it paradoxically became more intelligible"

"The Firewall 640x Stellar infused each note with deliberation and substance without sacrificing clarity, a balance I found deeply compelling."

"revealed just how accomplished it is in the realms of dynamic span, authority, elasticity, and sheer rhythmic flow. With the LessLoss engaged, the presentation grew larger, quicker, more punctual, immediate, immersive—and ruthlessly precise in landing each bass jab without a trace of fuzz or bloat. Remove it, and the same track turned lighter, more mechanical, tonally flatter, anemic, and markedly less elastic, as though its funkiest instincts had been quietly siphoned off."

"The list of improvements was extensive: deeper low-bass reach with markedly superior control, impact, focus, and articulation; more precisely defined images surrounded by more tangible breathing space; higher contrast and an increased sense of effortlessness; and a vocal presentation that was not only clearer and more textured, but also blessedly free of the nasal, prickly edge it can otherwise exhibit. Despite the added gravitas—meat on the bones, if you will—and a more atmospheric, earthy tonal balance, the result remained highly resolving."

"With the LessLoss positioned ahead of my DAC, the entire soundscape seemed to pull me inward, enveloping me in its encompassing majesty, eerie allure, and elegiac sadness—meditative, almost spiritual in nature. The moment the filter was disengaged, that deeply personal connection vanished."



"This device elicited an emotional response that felt both genuine and profound, elevating the experience to an entirely different plane."

"The Firewall 640x doesn’t merely shine—it radiates. I found it remarkably potent, and frankly amused by how much it managed to extract from a system whose power delivery already felt dialed in to a degree most listeners would never pursue."

"That, ultimately, is its true appeal. If you’re running a fully sorted, high-end platform yet remain open to radical measures to push it further, the LessLoss Firewall 640x Stellar may be precisely the reminder—delivered in no uncertain terms—of just how much more your system can still give, even when you believed you had reached the limit."

Note: The first statement below refers to Dawid Grzyb's article recently published.

"Giant Steps work very well as classic hard footers"

Note: In this piece, author Srajan Ebaen extended the review by trying different 'unorthodox' applications, such as placing Giant Steps on top of equipment, tacking them to the back of active speakers, and placing them on speaker cable risers directly beneath lightweight speaker cables.

"Playback's reverb times seemed very subtly extended. It gave my tunes a faintly bloomier richer feel."

"As someone sensitive to WiFi (rare) and the bluish flicker radiation coming off computer monitors (common), these footers appear to have benefits."

"Mellower, rounder and richer. Also, my brain bummer of electric prickling lessened with the GS in place, my eyes relaxed more."

"In this weird but efficacious context, those were noteworthy gains."

"This being far from my first LessLoss rodeo, Louis is more of a G-man. Gorgeous not raw is his aim. In that he's fantastically consistent across his portfolio."

[Now using Giant Steps directly under lightweight speaker cables:]

"With four Furutech risers per each channel's 3m [speaker cable] lead, I could max out at eight GS total to cover all my bases. Yet one on the Furutech [speaker cable support] closest to the speakers was sufficient. The gain was in suchness as tied to contrast ratio and presence. I heard it particularly during microdynamic crests"

"my subjectivity enjoyed the Giant Steps' 'non-footer' influence [meaning not using them directly under individual components as intended]"

"...was instant and hardly subtle."

"digs sensibly deeper and feels more agile, substantial, anchored, defined, controlled, elastic, composed, powerful and dynamically keen."

"The entire perspective gets cleaner and more specific, while vocals and instruments liberated from excess grain and edginess develop the extra density, color, smoothness and articulation."

"Backdrop becomes inkier, cleaner, more moist and busy with nuances that are easier to track and focus on."

"The landscape in front of us grows in size and raises its complexity, while all the sound sources rendered therein are more in focus, expressive and contrasting."

"Giant Steps venture even deeper by injecting even greater heft, juiciness, backdrop inkiness, sensuality and moisture into the music."

"Of the three compared footers, with Giant Steps my system produced the most dense, atmospheric, anchored, dark and velvety sound."

"it worked really well."

"quick, controlling, resolved and composed"

"When Giant Steps were on duty, my system made music noticeably more relaxed, flowing and sensual than with the other two footer types."

"the sensation of enveloping space, ambience, soothing mood and enjoyable flow particularly on calm minimalist tracks was unique, strong, very likeable and as trippy as the design’s principle itself."

"very high level of listening comfort"

"gains all around."

"just as the manufacturer’s Firewall did before it, today’s tiny nicely dressed robust footers changed a lot in my system. So much so in fact that I consider both these designs as equally effective and wicked on that score."

"very surprising and performance-wise quite the step up indeed."

"immediately produced a noticeable change in sound."

"the effect was even more pronounced."

"a significant transformation in the sonic message and the overall energy level conveyed by the system."

"increase in perceived resolution"

"allowed the mids to emerge with more clarity and natural articulation."

"striking clarity, grain-free, with micro-dynamics"

"more articulate in its attack and tonally richer, with a resonant quality that heightens the realism of the performance."

"Piano keystrokes become more expressive and detailed."

"Giant Steps enables a clear disentangling of harmonic lines, maintaining clarity, emotional expressiveness, and engagement that surpasses what’s possible without them."

"a remarkable focus projected into space with almost tactile intimacy."

"Breaths, inflections, and the slightest modulations now come through with greater presence and communicative nuance."

"The guitar gains attack and brilliance without ever sounding overemphasized. Harmonics are more audible and seem to extend into space more freely and naturally."

"The double bass moves closer: its fundamental notes are full, rich, and vibrant."

"draw nearer to the natural expressive core"

"leave us wanting to hear one more track… and then another."

"more coherent, more stable soundstage where each instrument acquires a precise and tangible placement."

"The midrange gains presence never exaggerated or unbalanced. Voices become clearer, more centered, yet weightless, as if the sound were emanating from a living body right there in the center."

"Subtle details once veiled now surface naturally: secondary reverberations, spatial reflections, underlying harmonic vibrations that previously remained hidden emerge with ease, as if the signal itself had been partially cleansed of an invisible yet ever-present noise floor."

"undeniably perceptible."

"brings back to the sound that elusive sense of spontaneity and coherence we often chase for years"

"The Giant Steps don’t change the tonality, and they don’t alter the sound per se. What they change is how the system breathes. They do this gently, but with a tangible effect, regardless of the setup. Certain elements that previously went unnoticed begin to reveal themselves, the soundstage feels fuller and more expansive, the bass tighter and quicker still energetic, but now delivered with more grace."

"one of the very best designs"

"very useful with all kinds of speakers"

"Rounder and fleshier vocals, wider color palette, increased fullness, longer decay and weight upstairs, higher clarity and lesser shout, edginess and grit are the benefits"

"I can't fault speaker Firewalls for anything in particular"

"these devices are free from any sonic downsides"

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

"Firewalls don't add anything audible to a system's voicing that is not already there in the first place."

"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."

"changed more than I initially thought it would."

"deeper reach and firmness, higher juiciness, greater textural provision, additional nimbleness and more nuanced general MO to the noticeable increase in clarity, more raw horsepower, contrast pop and dynamic span."

"clearly a souped-up engine."

"had me fair bit surprised in the dynamic department."

"newfound muscularity, authority and snap reserve"

"I wholeheartedly recommend to everyone."

"works equally well with all kinds of speakers."

"It goes about its business so well that financing it shortly after speakers is an elegantly small cost-efficient route to instantly upgrade them."

"sensibly larger performance hike and parks a nice dynamic twist on top"

"speaker fans not yet familiar with this LessLoss tech but intrigued by today’s Stellar may find its input very surprising and quite possibly also freakishly large."

"I am ready to declare Giant Steps are the State of the Art footer."

"The resolution is extremely high and very engaging with more transparency and much more accurate timbre. The improvements run seamlessly across the audible spectrum."

"Blacker background, more layered soundscape, greater dynamics? Yes, yes, and yes!"

"But the tonal colors from the life-like timbre are the most mesmerizing."

"I instantly noticed the improved resolution with the Giant Steps."

"They are in a higher league."

"Cymbals were highly resolved with no apparent smear."

"Voice was more analog or natural - there was no grain."

"The bass was tighter."

"The Chinese drum cut had outstanding timbre. Music was emerging from a much quieter soundstage."



"Timbre was improved and there was greater resolution. The bass was very impressive. Instruments were not masking each other. The orchestras were more resolved and layered front to back. The soundstage was very clear and the instruments were precisely located."

"There was a clear sense that the music was getting better over time."

"I was reveling in the excellent resolution and timbre which gave me a very "you are there" experience."

"There was more inner detail and the air in the recorded venue seemed crystal clear. There was more layering with orchestral works and the soundstage came further forward in the front corners. The music was becoming more real and I felt like I had moved up to the tenth row in the theater. I could hear the hall sound clearly as the reflections gave recordings a more accurate sense of space and size. Turning the volume up felt like walking down the aisle toward the stage with the performers or the orchestra becoming appropriately larger."

"...from start to finish, my toe-tapping the whole time."

"The guitar notes had an even faster attack and were more transparent. The extended vowels in Joni's singing revealed even more quiver and microdynamics. I had greater cognition of words in the lyrics."

"Tears welled up in my eyes."

"Giant Steps brought me to the edge of being there - and not just with one CD. Almost every CD I played felt like it had been dramatically remastered from the original tapes."

"The Giant Steps gave me a window into the lyrics, musicality, and nuance of the music. They also enabled a personal connection to the singers and musicians."

"My recommendation would be to start at the front end(s) of your system and work your way toward the speakers as far as your budget allows."

"Having tasted the purity and immediacy of the music with the Giant Steps, I missed them when they were removed. Could I live without them? Certainly, but given the available resources, I'll keep them, thank you, and likely order more."

"It is clear the Giant Steps are destined to become the Bitcoin of High-End Audio."

"Giant Steps have taken me up what feels like the final ascent. I feel like I could declare "game over" and live out the rest of my life enjoying my LP collection."
