"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."

LessLoss products reviewed:

Entropic Process Firewall 640X
Entropic Process Firewall for Loudspeakers
Entropic Process C-MARC power cable
Bindbreaker equipment feet

"improvements were pretty much qualitatively consistent among the entire group of LessLoss products."

"definitely give the Entropic power cord consideration."

"Entropic Firewall 640X provided a more significant quantitative improvement"

"Firewall for Loudspeakers and Entropic Firewall 640X: the combination of the two was better than either one alone. Synergy."

"Firewall for Loudspeakers and Entropic Firewall 640X and the Entropic C-MARC power cord: better still."

"becomes obvious once you recognize that it's missing. And this is the key to these products."

"It wasn't until I removed them that I recognized the noise and distortion they had removed. Once I was tuned it at this level, I could then easily recognize their contributions on a relatively quick A/B comparison. In a way, it was just an extension of the process of becoming an audiophile - learning how to listen, but at a higher level than before."

"The removal of noise, more obvious in the treble, but effectively throughout, allowed more inner detail to emerge from the now blacker background."

"improved transparency"

"Without the LessLoss the music had a certain low level of what I'll call "wild behavior". These were micro flashes tone bleaching out, or amplifier clipping or ringing or notes smearing - tiny little distortions, similar to what many recognize as "grain" that reminded me that I was listening to electrically reproduced music, not the real thing."

"These micro distortions can be somewhat exciting at times, such as the striking of a cymbal, and somewhat distracting at other times as I "struggle" to interpret what a musical note or a syllable "should" have sounded like."

"this "struggle" takes mental energy and it tenses up the body."

"The LessLoss works against that "struggle" by removing a layer of haze, making the music and lyrics more obvious. Micro-dynamics and nuance of tonality appear that were unheard of before. My body relaxed and absorbed the music as it came to me, rather than forcing me to lean into the music. The difficult lyrics were more easily understood."

"On my compilation CD I have many signifiers; phrases of words or notes that are challenging for a system to reproduce and challenging for me to hear clearly or cognitively comprehend. With only these few pieces of LessLoss gear in the system, I sailed right through these rough spots, and in most cases, they were the best I had ever heard them."

"strips out noise without interfering with tonal quality or dynamics"

"noise-free listening experience"

"I can testify that it does not interfere with tonal quality as my rig continued to sound the same in that regard, and dynamics seemed unimpeded, too."

"it was very relaxing."

"The Bindbreaker footers outperformed the MiG SX and I expect the current version with the dimpled bottom plate will yield an even higher resolution."

"they [Bindbreakers] performed astonishingly well throughout the audible spectrum with my DAC."

"the Bindbreaker may work best with solid-state gear, but you have to try it with your gear. When it works, it works very well."

"my biggest gains were with the Entropic Firewall 640X and it worked best on the AC line directly feeding my DAC."

"The 640X also worked very well on my preamp where the improvement was experienced with each of my sources."

"keep in mind the forthcoming [LessLoss] power distributor with built-in Firewall 640X technology"

"the Firewall for Speakers made a relatively cost-effective contribution that benefited each of my sources."

"do not make the mistake of thinking power cords are less significant than the main components in your system."

"Sometimes we discover something we like that we didn't even know was an option or a benefit at the outset of our quest. This is what happened for me with the LessLoss gear reviewed here."

"The emotional seductress was replaced by the silky voice of a polished jazz singer. Firmly planted in the 'here and now' of my listening chair, I relaxed and enjoyed the music, unencumbered by any personal emotional drama, just experiencing the beauty of the music. That's the essential difference LessLoss brings to the game. Relax and enjoy. And they do it as well, if not better than anyone else."

"If that's your audiophile destination, I highly recommend you give LessLoss a listen. This Lithuanian company deserves a lot more recognition in the USA."
