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.

Firewall Module

Date Added: 09/21/2021 
The following story is my journey with the Firewall 640x DIY version, I have collected my email feedbacks to Louis to give an impression of my experiences:
May 18th , 2021
Hi, finally I have installed the 640x’s in my system (DIY oakwood boxes), one in front of my source and my preamp and the result are very, very nice! I’m not very surprised because I had the opportunity to test one 64x in my system before these. However, with the new babies the sound is more palpable, 3D, organic, liquid and involving (the only parts that have had more impact in the overall sound in my DIY journey are the complete replacement of my coupling caps with V-cap ODAMs).
May 28th
Last evening things really started to change – and what a spectacular improvement! I have totally new experiences with my so familiar music – or, which I thought I knew. Some reviews report they crank the volume up with the Firewall installed – not me… Actually, I have to turn the volume knob down because of the tremendous increase in macro dynamics. – I guess the purer mains have freed up more horsepower’s which now are used for dynamic music amplifying and not noise amplifying? Now I have an huge room without walls, expanded in every direction left, right and back, and also to some extend upwards – and it so defined and controlled – and the bass, yes the bass... Also, I take this as a sign of good quality of my components before the installation, which just were, and hopefully still, are waiting to be released.
I know I have a configuration that you not recommend; before the Firewalls I have some main filters from LC audio, which actually have no ground connection after the filter (however, I have a true ground rod in the garden on the LC filters main side), meaning that the ground part of the Firewall is not active. However, the impact from the Firewalls is to my ears still significant. Yes, I can hear you thinking; just remove the LC audio filter – which for sure I will try later.
On Lois’ recommendation as the next step I ordered 3 x 640x for my amps (and one for my projector).
July 8th
Hi Louis, all my gear now has their own Lossless power conditioner, the result is fine, but the biggest improvement was on my pre and daq. The effect on amps were more subtle, although the bass went tighter. Maybe a little bit more colorful, but not night and day effect.
I tried to remove the LC Audio net filters originally filtering the mains (daq and pre) in front of the new LL640x; big improvement on the daq, but just confusing on my pre – however my pre is by nature not grounded so I suspected maybe it could be explained by that? However, I reinstalled the LC filter on my pre again - in series and in front of the LL640x. Hm, music in focus again and with better dynamics, but after some time I heard a kind of unpleasant sharpness especially on vocals. Strange. I thereafter swapped the mains L and N phase and the sharpness went away – so that inspired me to again remove the LC filter – and now it sounded nice!
So that’s it – now playing purely with LL640x on three power amps (1 to my sub amp), on my daq and pre. Sound is great, but the effect was definitely biggest on my source products. The effects kind of sum up in more “to be there” effect. Of my power amps, the effect on the Crown to the sub was the easiest to hear, not on the bass, but on the higher frequencies??? – could it be the Crown originally polluted the power to my system, which now is cleaned up after installing the LL640x?
Not to forget; the effect on my projector was nice, deeper blacks, more nuances in shadows and dark scenes, more saturated colors, sharper, and more 3D pictures – very impressive effects (– the power cord on the projector is 3.5 m questioning my idea about lack of big effects on power amps?)
Aug 18th
Hi, just to update you on my experience, the sound of my system is now on a new higher level! This happened just some days ago - think the burn in period is much longer than my first expectations! For now, I think the LL640x improve my amps sound equally to my pre and daq!!!
September 20th
Sound is even better than reported Aug 18th, the musicians are in the room. Before boring recordings are now involving and interesting, kind of understanding more of the content and what the musician’s expressions. This has been a great journey, well worth the money spent and the burn in period! Thanks!
Regards, B.Rud, Norway

Bindbreaker Vibration Control Equipment Foot

Date Added: 09/17/2021 by Tony.Oz
As an audiophile of many decades vintage and having selectively sampled top-of-the-range products from many 'big-name' audio brands over many years, I've ended up replacing them with LessLoss' incredible breakthrough audio products (including power cables, IC cables,main and loudspeaker firewalls), I've come to appreciate the wonderful sonic improvements they've brought to my two systems and ended up either selling or given away those from other sources. It is ,of course, important that the components of an audio system is well-matched and properly set-up

I have been using the Bimdbreakers since they were first introduced and was surprised at the difference they made when installed on my CD player (CDP) , tube amp and DAC - a marked improvement in definition, depth of sound field and clarity.

When Louis announced the upgrade for the Bindbreaker - with just the dimpled baseplate only - I was initially sceptical and decided to try just a set of 3 for my CDP. They arrived a day ago and was I surprised that they sure as hell delivered - in spades. There was even greater depth and definition with added clarity and some pleasant subdued increase in the bass. I listen mainly to classical music and occasionally some light popular music (Diana Krall, Eva Cassidy etc). Female voices and strings in particular seem to benefit even more.

Well, I've just placed another order for more - Bindbreaker dimpled baseplates that is.

Unlike many audio enthusiasts who regularly upgrade their main audio components ( amps, source components, DAC etc), I have found it more beneficial and economical to upgrade the performance of my system with said LessLoss superb products.

I have no business or personal ties with LessLoss and must stress that my impressions are purely personal.

Bindbreaker Vibration Control Equipment Foot

Date Added: 09/17/2021 by Joerg Meinhardt, Germany
Bindbreakers update and upgrade

Quite some time ago, I wrote about my experience with the first Bindbreakers in my HiFi system:
09/01/2019 by Joerg Meinhardt

Since then, there are Bindbreakers everywhere in my HiFi system, just except for the loudspeakers, which need a more stable platform for grandkids and dogs running around and easy moving for speaker positioning.

I am very happy with these 8 sets of 3 Bindbreakers and will always put them on any new device in the future as well.

The sound changes are always similar, no matter which device it is, as my findings from my first review:
- Soundstage deeper
- Better separation of instruments
- Airy open highs
- Cleaner but even more colorful midrange
- More punch, especially in the bass
- More, deeper, and better controlled bass
- Voices especially from a deeper stage position sound more realistic with less distortion
- Less resonances in mid and low range.

The only downside I see, is the required careful handling with setting the device vertically on all feet at the same time. You should not move the device around without lifting from all Bindbreaker feet at the same time. But sometimes the device moves around due to pushing a switch or plugging in a cable. So, I cannot follow the instructions perfectly, but it seems to work ok anyways. A little hint, get yourself some balloon kind of tools, that can be pumped up …“Inflatable Air Cushion Lifter”. Not perfect, but better than plain hands.

Now the news from last week … the new base plates … and how it worked for me.

I immediately ordered all 24 base plates as replacements without testing with some/one first … I trust Louis …

And what was the result for an almost 2000 USD upgrade .. no regrets and very happy:

Indeed more natural sound, especially noticeable with voices, and a much better stage positioning and control, and I would say even lager stage. Overall more natural and articulated.

A great deal for me and big thanks to Louis and his team!! One more reason to trust them :)

But, when I held the first Bindbreaker in my hand (2019), I was curious, why they did not come with these dimples … Without being able to argue, why I would prefer this … But now I know after the explanations from Louis :)

And don’t worry about the mixed colours for the upgrades (top grey, base plate brown). It looks actually friendlier and does not seem to be unwanted or a mistake … I love it !!

Echo's End

Date Added: 08/24/2021 by Jörg from Dortmund, Germany
[Echo's End Reference, upgraded from Firewall 64x technology to Firewall 640x technology]

When I installed the DAC during the week I hadn’t too much time to take a listen during the week.

As I’m very familiar with the Sound of the Reference DAC over the years, I’m pretty sure to remember how it sounds, especially with extremely familiar discs. Some might say, that this is difficult without direct comparison of the DAC with the older incarnation of Firewall modules to the one that is equipped with the actual new Firewall modules, it is new, you want it to sound better, but that might only belong to your imagination. And that might be the case with other gear, tweaks, cabling, whatever, when the difference in sound is very small. You wish it to be, but you can’t be sure.

Now I listened to my most familiar discs again, and the difference is not subtle, it is simply astounding!

Never would i have thought of such a big improvement, coming with the replacement of the older Firewall modules.

Everything is brought out better, acoustic instruments sound incredibly natural and real. Everything has more depth and contour. It simply sounds more energetic and precise. The reverberation of voices and decaying instruments lingers longer than before. Basses are more profound. And again, I’m hearing a cornucopia of details that were previously imperceptible.

And with excellent sounding discs, my room is flooded with sound, I have the feeling I’m bathing in it. It totally surrounds me.

To me, this is relaxed listening with a quality of the highest degree and this comes without any edginess in the high frequencies.

Funny thing is, that the biggest improvements in sound quality come with those discs which sound already fantastic. The DAC can’t repair what’s gone wrong in the production, recording or the used quality of equipment with mediocre sounding discs. I’ll get an improvement, but not to the degree with already great sounding discs.

The DAC transports music and gets me simply magical bliss. And for the moment I’m absolutely sure that it hasn’t shown it’s full potential, as there are some parts like my CD-Drive and the AES/EBU cable that are not on par with the quality of the DAC.

The DAC with the new Firewall 640x modules is simply awesome!

Now, I’m up to further listening again…

Thanks so much. Have a nice Sunday and best wishes from Dortmund.

Jörg

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.

Firewall Module

Date Added: 07/27/2021 by Chris L
I recently purchased the C MARK 640X after reading published reviews. As recommended in the review I installed it on the input to my power board which supplies the digital front end of my system.

This is an amazing product, I was surprised at the difference it made. The improvement was immediately noticeable and significant. There is more air around instruments, background is quieter and bass is more defined.

I think this is the best value improvement I have made to my system and being a passive device it will last for ever. Well done on another great product.

C-MARC loudspeaker cable, stereo pair; Blackbody; Firewall Module; C-MARC Classic Power Cable

Date Added: 07/18/2021 by Joshua J. Wright
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.

Associated Equipment:

The entire system has evolved over the last 17 years. The only components that still remain are the speakers and upgraded versions of Audiopax Model 88s which were upgraded to MkII status in 2009. Every component including the cabling, electrical conditioning, vibration control, and room treatments were all selected after careful auditioning and confirmation of their sonic synergy with the overall system. Consequently, each addition has advanced the sound in a desirable direction. Many components have come and gone to arrive at its current state.

Firewall Module

Date Added: 07/08/2021 by Nils Berntsson
The C-MARC FW640x elevates the sound to new hights. The predecessor - the C-MARC FW64x, provided excellent transients, 3D perspective and a clear sense of the ambiance of the recording venue.

However, the C-MARC 640x improves on all parameters - an outstanding procuct.

Congratulations on yet another success!

LessLoss History From the Very Beginnings

LessLoss started its business on Audiogon in late 2007. Within the first couple of month, word about LessLoss spread like wildfire among Audiogon members. Here is the feedback received from our clients during our first year of operation. This is from even before we had our own website.
