C-MARC bulk wire and cable

Date Added: 12/20/2020 by Pascal, from Guadeloupe
Are you ready for the C-Marc bulk cable "Large" verdict in my high efficiency speakers (96.5 db!)?

Well I'm not going to use all the audiophile terms but the only thing I can say is that these cables bring finesse and allow the details to have more materialization, they are a little more embodied, of authenticity!

While waiting to familiarize myself a little more, I am saving up to test the DIY Firewalls for loudspeakers! So The sequel in a future episode!

Thank you for allowing me to improve noticeably but surely listening to my system!

C-MARC loudspeaker cable, stereo pair; C-MARC RCA unbalanced signal cable, stereo pair; C-MARC Classic Power Cable

Date Added: 12/12/2020 by Harold
I have looked at many designs of high end cables. None of them stand out in sense and simplicity like the C-MARC cables do. All the variables that influence sound (capacity, inductance, skin effect, strand jumping, dielectric constants etc.) are optimised in the most elegant solution I can think of.

Having made me very curious I bought some about 3 months ago, starting with one Entropic Process Power Cord, a pair of interconnects and standard C-Marc loudspeaker cables.
I was so impressed that I decided it really pays off to feed all the equipment with Entropic Process Power Cords.

Most impressive is that all the glare and aggressiveness in the sound I was used to in some recordings completely disappeared. And this without any loss of detail and speed.

Violins that are meant to sound fierce, like in Shostakovich’s string quartet no.8, can sound too harsh in a resolving system, even when played with the best equipment.
I love the energy of Isabelle Faust but superimposed with high frequency noise it is hurting my ears. Listen to her solo in Beethoven’s violin concerto and you will know what I am talking about. Jimi Hendrix surely would be impressed.
During crescendos of large choirs it may sound like the microphones were clipping during the recording, resulting in nastiness in the high notes.

Recently I upgraded the speaker cables to the C-Marc Entropic Speaker Cables. They take away that last bit of glare and let you experience the instruments and voices in its pure essence. Music sounds so true to life, it is very difficult to put in words. You can feel the instruments themselves bringing the air into motion.

C-Marc cables don’t add or emphasise “a taste” to the sound. C-Marc cables are like Tai Chi masters, they just let the energy pass through without wasting or blocking it.


Equipment: Streamer Melco N10, DAC Sonnet Morpheus, Amp Bakoon AMP-13R, Speakesr Bastanis Matterhorn mk2. Other cables: Fidata ethernet, Curious Evolution USB.

C-MARC RCA unbalanced signal cable, stereo pair; C-MARC bulk wire and cable

Date Added: 12/11/2020 by Barnabás Komáromi from Hungary
Yesterday I purchased my first LessLoss cable. I wanted to put an analogue interconnect between my player and my amp. My stereo system is not really high end category because in the past years I invested more into headphone gear.

I could not use the standard C-MARC RCA that you make (with those Large Xhadow silver plugs), because my "cheap" devices have the RCA sockets too near for each other.

So my technician colleague assembled a cable for me, using C-MARC bulk coax and these "low weight, nickel-free, gold plated tellurium copper" connectors.

Why C-MARC for such entry level gear? Because I wanted to buy one reference cable, that stays in my system even if I upgrade electronics. Also, I wanted something flexible. I hate thick PVC.

From the first minute, my system showed a completely new image. Transparency improved and at the same time I started to hear the limitations of my player and the CD discs as well.

What I like about this cable is that it's not trying to make everything beautiful like a fairy tale. It makes my system more honest, more straight. At the same time it shows the pure details, the small details in space and time.

So I'm happy because now I can listen to my stereo with my wife and I don't have to go always to my headphones.

I tested a lot of your products in other systems for the past years and I knew that they are working, but it is always so intense, such a milestone to experience good changes in your own device chain.

Thanks again and I will be happy to continue recommending your products.

Firewall Module; C-MARC Classic Power Cable

Date Added: 12/04/2020 by Colin Gray
[Power distributor with onboard latest technology Firewall and Entropic Process C-MARC hook-up wire throughout]

The Distributor has been in my system for about a week and a half now.

I decided to swap over from my existing powerblock in two stages, first being the front-end components supplied by the Entropic Process C-MARC power cords, but leaving all the amps fed by my old cables/powerblock. The improvements were obvious and along the same lines as the Firewall for Loudspeakers. A couple of days later I swapped my old power cords to the new Schuko plugs and fed the amps from the new Distributor. Again, the improvement was obvious.

Given that my system has so much LessLoss conditioning already, each of which brought about significant improvement, the fact that the Distributor has filtered out so much more noise is both remarkable and disturbing. Whilst I am truly impressed by the new sound, I am concerned just how much further one could go!

This was an expensive upgrade, but the result is simply fantastic and I know from experience (and despite the Entropic Process) that it will still improve over time.

One thing that I have noticed and is worthy of mention, and more apparent after this upgrade than any other, is that so much ‘noise’ (that I previously did not know was there) has been removed from my system that it now requires quite a bit more volume on the pre-amp.

Congratulations once again to you and the LessLoss team.

C-MARC loudspeaker cable, stereo pair

Date Added: 11/30/2020 by Andor
Before purchasing the C-MARC Entropic Process loudspeaker cable, I wondered if it was worth the extra expense compared to the original C-MARC. Now I know: absolutely!

I was very pleased with the earlier version, but the fantastic experience with Firewalls, Entropic Process power cables, and Firewall for Loudspeakers, suggested it would be good, even though I had no idea how good it was. The cable is constantly still running in, but from the beginning it was simply much better than the previous C-MARC speaker cable.

The previous reviewers have already described it, but what's obvious to me:

- Huge space,

- Musicians in the room!

- Great progress has been made in the separation and placement of instruments. I've never heard the high notes sound so beautiful.

- Mid-range expressive and detailed, with previously unheard sounds, air quality, spatial positioning.

- Fantastic purity I did not expect!

- And the dynamic slam goes down like never before.


Very cool. The Entropic Process loudspeaker cable almost kicked the door in and my chin nearly fell off. Oh my God! In my opinion, this excellent cable will soon be rewarded with a prize of some kind!

What I love about LessLoss products is that they make the listening experience very easy and without fatigue.

Thank You, Louis, again!

Bindbreaker Vibration Control Equipment Foot

Date Added: 11/18/2020 by Stephen Braude
I now am using 5 sets of 3 Bindbreakers, under my monoblock amps, SACD player/DAC, passive preamp, and Aurender server. In each case they've replaced, and outperformed some very good alternatives, including Spira Ultra Tuning Feet, Symposium Rollerblocks, and Isoacoustics Orea. I plan to use another set on my 2nd DAC. The other footers definitely have their virtues. But in every case the Bindbreakers yielded clearer imaging and more robust instrumental and vocal timbres (more, and more realistic, meat on the bones). I consider the Bindbreakers, at their reasonable price point compared to most serious competitors , to be one of the great bargains in audio history, not to mention a truly ingenious device.

C-MARC Digital Cable

Date Added: 11/13/2020 by Geir Fagervik
The first thing I would like to say about this cable.
It requires a long burn-in process, so be patient.

If you have not experienced that digital cables can make a difference, this is definitely a great place to start - and eventually end. Yes this is an endgame product, you can check off your list a need for future upgrades.

Why do I say so: My experience listening with Lessloss C-Marc digital coax cable, shows just how much critical information that can be lost in this link.
Think about this: If you decide to purchase an expensive source and Dac and not invest in a digital cable with the same quality, they will perform below par, and you will never hear the potential. This will affect the rest of the audio chain and the end result will suffer. Since it is the first link from the source itself, I will argue that it is more important than the analog interconnect and speaker cables. Loss in dynamics here will not come back later in the chain. Louis will tell you to get the foundation regarding power sorted out even before this.

The interesting part with the Lessloss digital cable is that it does not add anything to the sound. It really does not do anything except let the signal flow through without hindrance. That means it shows what the source really sounds like. It's easy to think that a cable that is so transparent could throw the system out of balance, and reveal the faults. It does the opposite. It will make the sound more balanced. Even if the source is colored, this will make it less so, because most other cables will distort the already colored sound, and this cable will at least not bring more distortion to the table.

In my case I use the Marantz ND 8006. This cd-player/streamer can sound overly warm if used as an all in one player/Dac. When I connect it to an external Dac, this warmth gets less pronounced. Getting the Lessloss digital cable makes this warmth sound natural. It does not erase the coloration from the source of course, but in my case I really enjoy the sound now.

My results with this cable is that I get a more organic sound. This can be heard on all types of instruments. It provides for a more natural timbre. The music becomes more vibrant and alive. Piano especially sounds liquid and relaxed. Musical passages are more connected. There is a precision in placement of instruments both in width and depth. The whole experience is more coherent. The attention is drawn to the music. This is not a digital cable that is impressive in its own right. This aids the music itself to be impressively portrayed. Therefore this is the digital cable for the music lover first and foremost.

Words that come to mind are natural, relaxed, transparent, spatially separated, resolved, holographic, and all this on a high-end level.

I have tested this against Nordost Tyr 2 and Argento Flow digital cables, costing from 1.700 $ to 1.850 $. The Lessloss costs 500$, and I would say that the Lessloss is superior to those cables. I think the Tyr 2 is more colored, and has a tendency to make the system sound more bright. I sold that cable and bought the Lessloss cable, and it was a good choice for me. The Argento Flow is more in the same category as Lessloss, but even here the Lessloss seems to have better layering and texture, and it is definitely more liquid. Anyone that has testet Argento Flow would know that bettering this cable is some statement.

I use this with great success on a mid-priced digital rig. I guess it would perform stellar on a fine tuned high-end system.
If you are in the market for a digital cable, do yourself a favour and buy this!

C-MARC loudspeaker cable, stereo pair

Date Added: 11/13/2020 by Matt Shelton
I received my entropic c-marc speaker cables quickly. They replace some older Lessloss cables that I picked up used, and for which Louis gave me a generous trade-in. I try to resist hyperbole, but am back in the throes of head-over-heels love as I am forced YET AGAIN to concede that the sky is the absolute limit in terms of what adding new LL elements to my already heavily Motek'd system will do.

All the things I raved about in my March review of the speaker Firewall filters are significantly further enhanced. My music is sounding even better at both softer and louder levels, hard for me to believe since it was already so enjoyable. It sounds so easy yet dramatic. Somehow, even though the intellect knows recorded acoustic music is still not quite real, the heart is happy to be fooled. There is no effort. Belief no longer must be suspended.

Please, prospective purchasers, you haven't begun to hear your gear at it's best until you have sorted your power cords and cabling with the best Lessloss product you can afford. Honestly, you can save $$$$ into the future by NOT needing to upgrade your system components once you have unleashed your speaker cones the Lessloss way. For the record, and like Louis, I am a professional musician, playing in orchestras and big bands, and I no longer feel cheated when listening to classical and acoustic on my system. Other genres can absolutely kick ass too. Excellent music in, absolutely stunning out...

After a nearly 40 year hifi journey, I have stopped missing a few components I stupidly sold along the way and am truly happy with my modestly ( cost-wise) high-end system. I am struck with sadness for designers and producers of hifi who maybe never heard what their gear could truly do, without the very best attention to the issues that Lossless has tackled. Maybe a few lucky ones did.

Another honest-to-goodness breakthrough success.

C-MARC Classic Power Cable

Date Added: 11/05/2020 
I’d like to think my current system ticks all the boxes audio reviewers write about: speed, detail, soundstage, etc etc etc. It was and is all there. But the LessLoss cables took it all a step further whilst making the music sound SO MUCH more natural. There’s the physical sensation of the subtle vibrance of matter itself, as if touching the instruments with your ears. Also most striking I found the clearer ambient information in the recordings. It makes the whole setup materialise in front of you. Tiny details that were there before but floating without spacial clues suddenly fell into place. The lowered threshold truly pays off.

I started with only a Firewalled Entropic Process power cable to the DAC. That only was already a significant improvement. Then I knew I had made a very sensible investment. After several weeks I couldn’t resist the temptation to order two more Entropic Process power cords, for streamer and amp.

If you have a highly resolving system and plan for a serious upgrade of a component or two, I strongly suggest you first upgrade to LessLoss entropic cables. Not only will you be amazed by the sound improvement due to the cables themselves, it also will reveal much clearer what components are capable of.

Of course there will be no miracles ridding the horrors of bad recordings and masterings.

I never understood what it meant: a silent cable. It sounded silly. Of course cables are silent. They don’t make a sound like a softly humming tube amp with 100 dB speakers. Now I do.

System: SotM SMS200 Ultra Streamer + PS-500 power supply / Sonnet Morpheus DAC / Bakoon AMP-13R / Bastanis Matterhorn Speakers.

C-MARC loudspeaker cable, stereo pair

Date Added: 10/20/2020 by John Zermani
The sound of my system last night was so immensely better than the night before that I’m at a loss to understand how cables or break-in could possibly result in the magnitude of the improvement I hear.


My “review” (below) of the C-MARC Entropic Process cables was premature, it seems, and my comments are nowhere near positive enough.


You are welcome to use what I wrote, but when I finally come to terms with what these cables can do and have done, I may be compelled to write another assessment.


Thank you for your years of effort; the results are greater than I could ever have imagined.



I received my new C-MARC Entropic Process loudspeaker cables on Wednesday, Oct. 14th.


I put them on my Cable Cooker for 3 days as this has always been essential for maximum sonics in my system; even when the manufacturer has instructed that it is unnecessary or not recommended.


After cooking, it normally takes ~ several hours of real music to fully maximize sound quality.


My reference speaker cables for the last 3 years have been Nordost Frey 2 cables (as the Valhalla and Odin cables are too much of a good thing = not good) because they are the only ones I could find that were both fast enough (the fastest so far) neutral enough (a bit cool sounding but not bright), very transparent with excellent resolution, and, most important: They get the timing right. This is NOT about speed; it is about all the notes, bass to treble, arriving at the right time with no smear or delay and with proper decay. No other cables I could find could do this. I had no options; but I was satisfied.


Given my results with your Speaker Firewalls and your power cables, I decided to try your C-MARC Entropic Process Speaker cables in the hope that they might provide everything the Frey 2’s provide and even more. The Early Bird discount offer made them that much more attractive.


I am pleased to report that I think I have found the only other cables that get the timing right.


But it’s much more than that: These are very “fast” cables, very transparent, with even better resolution than Frey 2 and better “body” and “weight” as well. Voices are a bit more ”human”, woodwinds and strings are a bit more “woody” and “stringy”, and the sense of reality, of being present at a “live” musical event, is significantly enhanced.


These are definitely not “warm” cables. The weight and body they portray are not bloated or “euphonic”. Neither are they “cool” cables as many “fast” and transparent cables can be. Instead, and in my system, they take me to the recorded venue where I hear, and experience, what I can believe I would hear and experience if I were present at the time the recording was made. Absent being there during the recording, one can never be sure of this of course, but the sound rings true to my many decades of listening to performances of live music. They seem to be the most dead-neutral cables I’ve yet heard; adding or subtracting little or nothing.


AND: They do this better than any others I’ve yet heard.


Your C-MARC Entropic Process cables are a magnificent accomplishment. As they are likely not yet at absolute, maximum performance (though very close) I am eager to hear what they ultimately achieve.


Thank you for a great product that advances the state of the art.


John Zermani.
