Mono and Stereo publishes LessLoss Firewall review

April 2012, author: Matej Isak
"What surprised me most upon using the LessLoss Firewall was the change. With the Firewall inserted before the passive power distributor, it felt more like adding a preamplifier rather than a power conditioner. Gain, fluidity, a blacker ground, dynamics, and a sense of space all seemed added. Something natural happened. Everything had more to do with the sense of an analog feeling of reproduction."

"The sense of space and depth of the music entered into a new positive realm."

"What avidly stood out was the grain-less sense of music and event. Articulation, timbre, pace... Everything worked and clicked more realistically."

"I can authoritatively sum up that the addition of the LessLoss Firewall to my reference system has been a prolonged study in neutrality."

"Dynamics, a natural timbre, and a prolonged sense of space were as they should be, and as a scholar and classical musician himself, he confirmed my impression that the bloom, articulation and liveliness were distinct merits and not mere colorations."

Mono and Stereo publishes preview of the LessLoss Firewall

"The impact from the LessLoss Firewall is far beyond from what I expected."

"It feels like adding a new preamp to the system, rather than dealing with "just" a power filtering product."

"Music entered into the room with a huge pace and a pompous step, knocking down the doors of perception. It is bigger and better, but not in typical Hollywood style."

UltraAudio.com review of the Firewall

June, 2011, author: Colin Smith
"LessLoss has delivered a triumph."

"The Firewall is an ultra-high-performance device that makes everything about my system sound substantially better and nothing worse."

"It's a pretty safe bet that the LessLoss Firewall will prove to them that there is something more -- and perhaps a lot more than they might think possible."

6moons review of the Firewall

February, 2010, author: Marja & Henk
"Without the Firewall, there was a stream of somewhat disconnected tones masquerading as musical performance. With the Firewall, there was musical performance built upon coherent interplay filled with spatial cues, proper timing and dynamic accents."

6moons publishes a preview to their review of the LessLoss Firewall

July, 2009, author: Marja & Henk
"Compared to many other power conditioners, the Firewall is completely passive. There are no transformers with their own EM radiation, no coils or capacitors, not even a lone fuse tucked away inside that 16kg log. The entire workings of the Firewall are based on a further deployment of the ideas and techniques used for the DFPC, albeit in enhanced fashion. Because the Firewall is intended to deliver the cleanest possible power, one must first identify what to filter out of the AC delivery."

"Because this filter has basically no capacity limits, we set it up as the power distribution center for our washer, dryer, water fountain, refrigerator and freezer. That combination formed a nice power-sucking consortium active 24/7 with cyclical loads for the desired effects. Audio observations to come next..."

Dagogo.com review of the LessLoss Firewall

April 2009, author: Ed Momkus
"An incredible increase in body and weight without any loss of pace. I was totally surprised."

"All tonal ranges now have natural weight and body, and have great PRAT and speed."

"The Electrocompaniet Nemo monoblocks are very powerful high-current amps, but they never hiccupped or even burped when used with the Firewall. Their speed and slam remained, but they became richer and, in my opinion, more tonally accurate."

"The Firewall seems to allow the components plugged into it to render very a natural-sounding presentation. This is totally consistent with the sound I heard at the Rocky Mountain Audio Fest when LessLoss teamed with Kaiser speakers, Mastersound 845 Monoblock tube amps, CEC transport and the LessLoss DAC 2004 to produce what I thought was the best sound of the show. Those of you that have several LessLoss DFPCs can expect the Firewall to multiply their effect and provide a very extended top- and bottom-end with extremely smooth frequency response and absolutely no glare."

Bound for Sound reviews the Firewall

December 2008, Issue #190, author: Marty DeWulf
"Once broken-in, feel free to plug anything you want into it - it can take it. Power amps, once the bane of all power line conditioners can't faze it. The limiting factor in this instance is the wall itself."

"Whether I was using the Pass XA30.5 drawing over 200 watts continuously, or some monster class A mono amps, the Firewall was a non-limiting element. It's fair to say then that Liudas' goal of making a line filter that would in no way limit or reduce current from the wall was successful - hugely successful."

"I was shocked at what I heard. The impact of the Firewall on the Big Rig was greater than I had ever anticipated. Pulling it and going directly to the wall for power resulted in my system sounding as if it were in dual mono. The stage receded noticeably with center images becoming exceedingly narrow while lacking dimension. Where did the air go? There were huge holes in the soundstage, and what had sounded like a continuous spread of music from left to right, and front to back was all of a sudden distorted; almost lumpy in some places and empty of sound in others - the scale of one image to another was out of whack. In an odd sort of way, listening without the Firewall was almost like looking into one of those carnival mirrors that makes part of you look fat and other parts thin. It was obvious that the Firewall brought to the music substance and gravitas, a weight and density, especially in the lower mids and upper bass that had never been there before. At the same time, you've never heard the highs in your system until you've heard them with the Firewall in place. Cymbals and bells that were blurry or sshisshy without the LessLoss, came into superb focus with a nice sense of clarity and resilience."

"One thing that didn't change was the superb dynamic action of the system. Plugged into the wall only, the Big Rig had considerable pop and energy with good leading edges. This is the area where most AC line conditioners from other manufacturers fail, even if only by a little bit. Most conditioners soften edges and reduce dynamic differences, especially low level shading. The Firewall thankfully left in place the macro dynamic action and shading which Liudas put so much effort into preserving in the first place. Additionally, the Firewall improved on the micro dynamic graduations and energy contouring."

Kaiser Acoustics on the Firewall

November, 2008, author: Rainer Weber, PhD., Technical Director of Kaiser Acoustics, maker of the cost-no-object Kawero! loudspeaker
"I never, never heard such a difference from a power filter. After one song I decided to switch our development system to be fed by a LessLoss Firewall."

"Sound stage is much more stable and the tone itself has the right harmonics. You can feel the body of the instruments. Wood sounds like wood. Brass like brass."
