C-MARC Classic Power Cable; Firewall Module
Date Added: 11/02/2021
My installation has two dedicated power lines: one for digital devices (Innuos Statement ---> DAC B. Audio), the other for analog devices (Hand made power distributor by Ludwig Audio ---> Preamplifier Thrax Dyonisos ---> 2 power blocks Tidal Audio for biamplifying pair of Tidal Agoria).
My power cable panel features TWL Obsession, C-Marc on streamer and DAC. The digital or analog interconnections come mainly from Sablon Audio.
I also have two LessLoss Loudspeakers Firewalls, and a C-MARC 640X firewall on the preamp. The second C-MARC 640X that I have just purchased will go directly to the DAC, whose power supply is much less optimized than that of the Innuos Statement.
My goal was to avoid pollution of the power current between digital devices among themselves, and between the preamplifier and the power blocks.
What a success !
On my DAC: immediately: more space, more depth, more precision on attacks, more control on bass, less background noise ...
The music is more immersive ;-))

C-MARC Classic Power Cable
Date Added: 10/07/2021 by Rejean
I now have three LessLoss C-MARC Entropic cables and five C-Marc 640x firewalls. My sound system is of a very good level and very musical, in summary (Antipodes K40 server, DAC dCS Rossini + Master Clock, WooAudio 3Es-Elite tube power amplifier, JL Audio F110v2 (2) subwoofers, Shunyata Denali 6000 v2 and Audioquest Niagara 3000 power conditioners and Stax SR-009s headphones). I only use headphones. I also took a lot of care with the Ethernet (dual switch SOtM, Farad Super3 LPSU, etc, etc,). I use several very high-end cables (ex: Nordost Valhalla 2 XLR, RJ / E and BNC 75 ohm, etc.), in addition to the Shunyata Sigma v2 NR, Voodoo Air Phoenix and Audioquest Hurricane power cables.
After several trials and configuration changes, I can confirm that the Lessloss cables are really impressive, especially at reducing noise level, improving resolution, increasing low and high frequency extension as well as transients. The soundstage is also greatly improved. The best results were obtained for the power supply of the Antipodes K40 server and for the power supply of the Shunyata and Audioquest conditioners. However, to power the WooAudio 3ES-Elite amplifier, I did not get a satisfactory result. Although very good the sound has become too analytical, a little romance is nice. I am even more impressed with the 640x C-Marc firewalls. They are particularly effective for powering LPSUs that power SOtM switches, the router, and the cable modem. The 640x firewall has also improved the sound quality of the Antipodes K40 server. For the K40 I use a C-MARC Entropic cable coupled to the 640x C-MARC Firewall. The presence and resolution of the whole system has been greatly improved. LessLoss products are a discovery for me. I am very satisfied. They bring a notable improvement in transparency, smoothness and musicality. When I say softness, I am referring to natural, precise, but non-aggressive tones that are very easy to observe with vocals and acoustic instruments. A veil has been lifted and the music vibrates. Congratulations to Louis and the team.

C-MARC Classic Power Cable
Date Added: 08/18/2021 by Rejean
About two months ago I purchased a C-MARC Entropic cable from The Cable Company. I installed this cable upstream of an Audioquest Niagara 3000 conditioner. This cable is fantastic, significantly superior to several more expensive cables I have had previously. I was impressed with the level of transparency and the beauty of the timbre that this cable provides. There is a magical side that I cannot describe. I start slowly, updating some critical cables (music server, DAC, switch, power supply, etc.) with C-MARC Entropic cables.

When I first read about the LessLoss technology I was a bit skeptical. Since I already loved the way my system sounded I had difficulty believing that it could sound even better than it already did. Louis assured me that I would be impressed, so I took the dive. The first thing I tried was the C-MARC power cords with ENTROPIC treatment. The 2 power cords were applied to the DAC and to the pre-amp. At first the sound seemed to close in and become less involving. By the 3rd day of listening it became apparent that I was hearing sound that was more coherent, and phase correct, producing a more musical overall result. Inner details, textures, and the bass all took a significant step forward. After experiencing these effects I went ahead and added 2 untreated Reference level PCs to the amplifiers which resulted in magnifying the effects noted in the DAC and Pre-amp.
After the power cords I was curious about what the Blackbodies (total of 4) would do for the sound. This addition caused the most significant initial sonic degradation of anything I have ever added to the system. It took about a week before the benefits became fully apparent. Strangely enough the biggest improvement came after leaving the system off for a week. When I turned it back on the sound had totally transformed. It was as if a switch had been flipped bringing everything together. Suddenly there was a clear open window of sound with extended decays and sustains surrounded by the acoustic space specific to each individual venue and recording technique. All frequencies were proportional, gone was the bass heavy bottom up effect I had noted earlier during the initial break-in period. Also gone was the increased dynamic slam and exaggerated dynamic contrast that was previously prominent. What remained was a very natural balanced, and detailed presentation free from any detracting artifice. The background was much more quiet, allowing the tiniest details to emerge effortlessly, as if being spontaneously emitted from the space in between the speakers. The imaging was excellent before, but now it was if the speakers actually ceased to exist. The sound also became more concise, focused, and clean; making it apparent how much extraneous noise was infiltrating all aspects of sound before the Blackbodies were added. Initially this effect made me feel like I was missing certain aspects of the music, but over time it became apparent that it was only distortions that were missing, as new worlds of detail were exposed from old familiar recordings.
After all of this I could not believe that the sound could get any better, but Louis provided me with this quote from another customer. “How the heck could I even listen to it and rejoice in it back then?” This from a customer who thought it could not get any better. That was the exact feeling I had after installing the Firewall For Loudspeakers. In total I have added 4 sets to the speakers. I could have easily stopped after the the 1st set, as the improvement in tone, micro nuance, and overall integrity of the sound was beyond anything I could have expected. However after adding the 2nd set I too was saying to myself “How the heck could I even listen to it and rejoice in it back then?” The whole sonic landscape elevated particularly in the bass region which became even more effortless and detailed. It was as if the whole system was upgraded. The music was just “there” without any veils or resistance to most minute details. The sound was fuller from top to bottom, with more life like nuanced transients, and deep deep views into the sonic fabric and the most delicate textures and tonal inflections. The system never sounded this effortless, as if it had become super-conductive and friction free. Talk about lifting veils. Consequently I now have 4 sets of Firewall for Loudspeakers installed.
At his point I thought there is no way things could get any better, but as it turned out I was wrong, again. Louis built a custom set of Jumper cables specifically designed to work with Avantgarde Trios with BassHorns. These jumper cables were made of C-MARC, ENTROPIC cable with a DIY Firewall For Loudspeakers as junction splitter box. As usual there was an initial sonic suck-out upon first listen, but over the course of the week the sound again blossomed into something I have never before encountered from the system. Even after adding all of the other LessLoss devices, the sound again took another leap forward. It is not that I didn’t think the system sounded good before, it’s just that the improvements were of a type I had not yet experienced. All of the other improvements to the sound were still present, but were now being presented in a new light. The soundstage, imaging, and acoustic space all seemed come together to form an aural illusion so seductive and infatuating that I cannot stop listening and rejoicing in the sound. This type of sonic improvement is difficult to put into words, but after you hear it you will know exactly what I’m talking about.
Effortless, organic, liquid, holographic, 3D sound reproduction appears to be a byproduct of not just eliminating noise from all power and signal carrying cables, but of also reducing the effects of environmental EMI and RFI which can permeate every component. That is exactly the result I feel has been achieved from using the LessLoss devices. It is very difficult to say which device has had the biggest impact, but I can say that they appear to work synergistically. Individually each device has made sonic improvements which after hearing I did not want to live without.
My compliments to Louis and his organization. They have have proven to me that it is in fact possible to improve on even the most impressive sound systems, regardless of how good they already sound.

C-MARC Classic Power Cable
Date Added: 02/24/2021 by Philippe Plumecocq, France
The Entropic Process is quite something, as there has been no drop whatsoever in quality whereas my power and speaker cables (Heimdall 2) had been in the system for well over 18 months, possibly two years... And the sound is getting lusher by the day! Quite an achievement from you and your team, please share my congratulations to all.

I thought I had a very musical system -whatever this means- with special attention to cabling and power in general. Just two power cables were not highest grade in comparison to the rest. Anyway, I could listen for hours and hours with great emotion, pleasure and without any fatigue.
Then I decided to change the two mentioned power cables by switching for the first time to Lessloss products and chose the C-Mark ones without Entropic Process. The result: After one week of burning-in I HAD to listen for hours and hours.
Then I added the Firewall for Loudspeakers. I have not been able to stop listening yet...
I’m still wondering what the Entropic Process could cause. I’m more than tempted.
Thank you very much, Louis&Team. What a pleasure!
