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."
