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.

C-MARC RCA unbalanced signal cable, stereo pair

Date Added: 09/19/2020 by Joerg Meinhardt
After many system upgrades with LessLoss products, that all were wonderful, I started to question my choice for my RCA connection. It was the highest level of Lavardin’s RCA cables, who happens to be the manufacturer of my integrated amp Lavardin ITx-20 as well, their highest level of integrated amp.

I saw great reviews about the perfect match of the Lavardin amps and the Lavardin cables, had a home testing and found it very neutral, natural, and clean, not brittle or grainy. And it was definitely better more detailed and open than my old MIT Spectral high-end cables from the 90s.

Since the RCA is connecting my only source, the LessLoss Echo’s End DAC, to my amp, why not look for a LessLoss matching cable :) Seriously, it was a matter of trust in the LessLoss products!

So, off went my order and the C-MARC RCA arrived very soon.

From minute one, it was so much better than the old one, that I did not even have to wait for complete burn-in to be convinced. More organic sounds, especially with voices, but also bells or plucking strings and all the rest :) Everything more palpable, widening stage in all directions, better controlled bass and more powerful.

And the burn-in … some days better, some days not quite as good, but always better than with my old cable. Too bad, not “entropic” yet. I know, what I am missing, because I checked it on the power cables … see my review from May 21, 2020.

And after 5 days I could not continue with my burn-in observations, because there was a big change in my system: the C-MARC entropic speaker cables arrived … see my upcoming review.

So now, all cabling is LessLoss!! … Well, the USB cable is not, but unfortunately there is no LessLoss USB cable so far, I probably would buy it immediately.

And I am so happy, especially, when I am again shocked how well voices sound. And finally the RCA upgrade made even background voices sound as natural as coming from real humans!!

Thanks so much Louis, for allowing me to bathe in my music now :)

PS: I am not paid for my reviews, and am not in the hifi business at all, and not related to any LessLoss staff or owner … My only role is being a customer, who has many decades of love for music and hifi and according experience and finds so much happiness with the LessLoss products, that I want to share with other customers. Too bad, that I did not trust this little never heard of abroad company, which I only found by “accident”, when I was just buying the more expensive Lavardin cables, while the LessLoss C-MARC early bird was on … So many hours of better listening lost, and could have saved money.

But the Lavardin amp stays!

C-MARC RCA unbalanced signal cable, stereo pair

Date Added: 06/21/2020 by david | Colorado USA
I can relax again. I have just put back into my modest system the RCA C-MARC interconnect that I have owned for about nine months. I have been trying some different cables since I have been thinking about converting to a fully balanced system.

As I have explained to Louis, the longer the cables are in my system, the better they sound. I am not talking a couple of hundred hours -- I mean 750+ hours on the C-MARC cables. Every time I pull them out to try something else, it is always the same when I put them back. Clarity, depth, and an overall sense of calm permeates throughout my system.

Now it is time for the Firewall for Loudspeakers...

First of all, I would like to thank you for the excellent cable and speaker firewalls and for the excellent customer service.

Now the RCA and triaxial speaker cables are also playing in my music system.
Although the cables haven't yet played music for long, I am already enthusiastic about the musicality.
For me, the cables and speaker firewalls are an absolute must in my music system.
Without this, I miss the tonal substance, the timing, the fine details and the musical energy that are so important for my perception of authentic music.
The music now sounds even more powerful, dynamic and homogeneous.

With these unique cables and FireWalls I have the feeling that I can fully exploit the potential of my music system (LDMS server including Ideon Audio 3R Master Time, Lampizator SE GG 2.5 Pacific Edition including preamplifier, NAT transmitter, Harbeth 40.2, etc.).
In addition, the cables and firewalls are very meticulously and precisely manufactured.
My eyes are spoiled too.

I am very happy that I chose LessLoss!
Stay healthy.

Thank you very much and good luck.

I own a number of well know and expensive Powercords that I use throughout my system. The Lessloss is clearly on par with the best for less. Used on the preamp of a system that was never bass shy, I felt like I had discovered another octave of music

Positive by Buyer Williamredburry (45) on 09-26-07

This cable was the BEST purchase that I've ever made!! I’m not affiliated with this product in anyway, but feel sorry for Audiophiles who don’t purchase these cables. Once Audiophiles try this cable, they will wonder how this product can be sold at such a low price. I’m baffled… In an industry full of snake oil, unethical cable retailers, enormous profits and scams - this LessLoss "Filtering Power Cable" is a "breakthrough product" which blows away the ALL competition at ANY price!!! I honestly don’t know how LessLoss can make a profit while using Oyaide connectors, hand braiding and an incredible passive AC filter. LessLoss "Filtering Power Cable" are sold from a manufacturer /owner /designer who is trustworthy, ethical, knowledgeable, and a pleasure to deal with. Take a chance!!!!, PayPal your money to Lithuania - and you'll be rewarded with great Customer Service, and the finest power cord made. Hear for yourself what you are missing!!! Thanks Again!!!

First-rate all the way! The cables are sensational, and the price is a steal. The 1-2 week delivery from Lithuania is well worth the wait. Liudas and Vilmantas at LessLoss are perfectionists pursuing their love for the art of music reproduction.
