C-MARC Classic Power Cable

Date Added: 06/05/2019 by Stephane P.
I have been a loyal client of Lessloss for years now, and have regularly upgraded.
I have the (previous version of) the CMarc power cords, alongside a FW64, and CMarc IC and speaker cables, and I love them. In my experience, these power cords (through the Firewall 64) provide high resolution and luminous clarity, with "air" and micro-information that is crucial to music reproduction "realism", but always in the service of the music. They are not artificially tilted towards high frequency nor analytical. I recently had the opportunity to compare them to Cardas Clear Beyond, and whilst also a very good cable, I preferred my Lessloss Cmarc power cords, for their extra luminosity, and sense of "live performance".

Firewall Module

I am listening to Born To Run (album) for the first ( the 1,000th) time. I am experiencing the excitement of a live concert two rooms away from the stereo in my home. I think it is important to start with that. This upgrade (from original to new 64X) is all about emotion and musical expression. The sound is much better to be sure but the MUSIC!

This is my fifth generation of FW modules and having been less than blown away by the step from 5X to original 64X (better but not huge) I felt foolish going for these. I really felt like it was purely OCD to have to have the latest- I mean it was still 64- no bigger number and I have a LessLoss power distributer with 5 of the 64 modules- and about double the list price - but I was "weak" and placed my order.

I fear that others may follow this logic and abstain. That would be a huge mistake. In my system, even with the loaded power distributer and excellent cables and a dedicated power line this is FAR and away the biggest upgrade ever. If you led me into the room blindfolded and told me my speakers and amp had been changed out for components of 5 times the price I would say it's worth the money with no hesitation.

I am not sure where to start with sonics. Clarity, detail ( but NOT treble edge), the most incredible soundstage and imaging I have ever heard, bass that no stand mounted monitor should be capable of- my wife says it hurts her chest cavity in the next room-but with tremendously increased tonality in the bass region.

The expressiveness keeps coming back as the main issue. It's not just that you don't want to change to the next track- it seems like it would be rude to the performer!

Three week break in so don't fret. Highest recommendation. No looking back!

New C-MARC™ Firewall 64X module


When I received the news that there is a new "C-MARC" Firewall module coming, I thought to myself whether it would be worth upgrading with these relatively minor changes to the former normal lead 64X. But I ordered one new Firewall 64X module.

So my configuration until the new one arrived looked like this:

Wall socket —> best C-MARC power cord —> old standard lead Firewall 64X module —> passive power distributor (no filter inside)
—> preamp (no change of power cable possible, captive)
—> power amp (no change of power cable possible, captive)
—> best C-MARC power cord —> LessLoss Echo’s End DAC
—> DAC to Preamp —> LessLoss Anchorwave cable
—> DFPC Original —> CD-player, used as Drive Transport only —> Light Harmonic AES/EBU cable (has to be replaced also with C-MARC cable at a later date) into DAC
—> Pre- to Power amp —> LessLoss Homage to Time XLR cable
—> Power amp to speakers —> C-MARC speaker cables

When the new C-MARC Firewall 64X module arrived, I let the the normal 64X stay and connected the new one directly to the CD-player. Right after installation the difference was shocking. I expected minor changes to the better, but this was extraordinary. It sounded better focused, instruments could be located more easily, I heard much more detail, absent before, and bass response had more depth and punch than before. So again, all the frequency parameters from the low end to the highest highs improved in a way that could only possibly be had with a change of gear that would cost several times the price of the new C-MARC Firewall 64X module.

Then I removed the new module from the CD-player and connected it to the Echo's End Reference DAC. I didn't expect a big change here, as the DAC received its power through the best C-MARC power cable anyway. But I was wrong again, the improvement was in the same league as it was on the CD-player. The differences are only slight and I couldn't pin it down exactly, sorry. That was amazing. It would be an interesting comparison to replace the C-MARC power cord with a DFPC Original on the DAC with the new 64X module in place. I can't try this, as I have only one DFPC left.

Could it be that it is a better way to get the new Firewall 64X module first, and upgrade to the best power cord later? If I could afford it, I would install the new C-MARC Firewall 64X module on every piece of gear and maybe a second one on the power distributor. I can't imagine how that would sound, but it seems to me that this would achieve a gigantic improvement.

So in the end I removed the normal 64X from the power distributor and replaced it with the new C-MARC Firewall 64X, so that everything in the chain could profit, but to a lesser degree each. And that was what I expected after trying the new module on the DAC and the CD-player.

So the new Firewall 64X module comes with a big improvement in overall sound quality. And the best is, that all these improvements come with no downside at all. The presentation after several upgrades over the years has improved yet again. The musicality is outstanding without any annoying artifacts at all. What I have now is a total relaxed and satisfying listening experience. The C-MARC Firewall 64X is an upgrade with the biggest bang for the buck. It may seem expensive at first, but it is not, when you consider what substantial improvement comes with it.


Thanks for this great product.

[C-MARC Firewall 64X]

Just a quick update on initial impressions. My normal policy is to make only one change at a time and in the context of the standard lead Firewall F64X, I only added them one at a time about one week apart. With that previous experience and knowing the very long burn-in times, I confidently chose this time to break with tradition and add two C-MARC Firewall 64X, to the front end (CD transport and DEQX) and leave the remaining three to be added to the power amps after my holiday.

After adding these first two at about 1130 am, I did not listen to any music until my normal listening session at 7 pm, so only some 7.5 hours of burn-in. Given my original FW64X were in my system for many months and well burned-in, I was initially expecting a slight drop off in SQ with the new versions as they would still need much longer burn-in.

However.......... improvements were immediately obvious;
First was the bass – clearer and better defined.
Then the vocals – same as above and therefore also more real.
Of course, by now I was hearing this to be true for all instruments and backing vocals.
It now seemed that every aspect of the track(s), vocals and instruments, were now enjoying so much more of their own space in the soundstage. For example, hearing backing vocalists further back in the soundstage and much clearer is simply fantastic.

One song nearly had me in tears such was the emotion in the female vocalist voice and that she sounded like she was in my living room !

Brilliant result, yet they are nowhere near run in and there are three more to be added to the power amps !!!!

Congratulations to you and your team, you have done it again.

C-MARC RCA unbalanced signal cable, stereo pair

Date Added: 05/08/2019 
The custom LessLoss C-MARC 1m DIN-RCA phono cable they made me is far superior to my Transparent and Purist Phono cables.

The Transparent cable is $3,000 retail and horribly noisy. I found out after purchase the Transparent is not well shielded and prone to pickup hum, huge problem in my system which I could never alleviate.

The Purist cable is $10,000 retail and better shielded but very dark and slow sounding.

In comparison the LessLoss cable is very quiet, alive sounding and creates a 3D soundscape versus Transparent and Purist’s 2D soundscapes... Basically, the LessLoss cable is *intensely* better than both in all aspects.

Thank you!

Firewall Module

Date Added: 05/02/2019 by GERARD FRANCE
In September 2018 I upgraded 10 Firewall 1X units to 10 Firewall 64X (1 of which was placed on the power inlet to the entire system). Results were excellent. Then later I experimented with a new configuration: placing two Firewall 64X units on each power inlet for prepreamp and 2 mono amps. Results were substantially better. A really new summit of sound quality. Then I tried the same idea with two FW64X on CD transport and on the DAC. Result: the same performance that I previously got only from analog sources. But it is very interesting that the sound is now not only better but also different. For the first time in my long life of listening to music I now feel with this setup as much pleasure when I listen to CD as I do listening to analog on vinyl.

Firewall Module

The USB Firewall key outperformed the Audioquest Jitterbug, ifi audio's i-defender and i-silencer. Just one of these transformed my car audio to a new level. Using it with an iphone with Audioquest Carbon usb wire and listening to Tidal and lossless files reveals never before heard nuances of music. worth it!

Echo's End

Date Added: 04/03/2019 by Darel Dillingham in Chesterton, Indiana
I got my Echo's End Original Saturday and played CDs ALL DAY Sunday and I'm in total awe of how much better it sounds than my $5000.00 Berkeley Audio DAC.

Louis, your DAC is totally amazing and I'm finally at a point where my digital is extremely enjoyable to listen to. You never cease to amaze me with the quality of your products and how much better your technology is than most of the other high end offerings.

Thanks for your genius and time.

C-MARC XLR balanced signal cable, stereo pair

Date Added: 03/25/2019 by Johan Pettersen
For about one week now I have had two sets of C-MARC XLR cables for the dac - preamp - power amp signal chai. There is a "cable history" behind this:
Ten years ago I had first generation Nordost Tyr cables. I then purchased LessLoss Anchorwave XLRs, and found them to be better - more detailed, at the same time more musical. Couple of years later I bought some second hand Valhalla signal and speaker cables. Big expectations! But I soon found out I still preferred the Anchorwaves. The Valhallas had some more dynamics and details, but the at the same time a bit lean and clinical in a way, and I got listening fatigue. While the Anchorwave signal and speaker cables gave me hours after hours with music. I then got Tyr2 a couple of years ago - more musical than the Valhallas, some more details and dynamics than the Anchorwaves. I thought I would stick with them. But then last year I purchased the C-MARC digital cable (from streamer to dac), and after some critical listening sessions it was no doubt: In my system C-MARC digital cable sounds better than the Tyr2 digital cable - more open and dynamic, and at the same time full-bodied and organic.
So now a new turn: Tying out the C-MARC XLR cables for the analog part of the signal chain. Impression after about one week: Incredibly wide soundscape, very articulate and dynamic, combined with full-bodied impression of voices and instruments. Extraordinary listenable and musical.

C-MARC Classic Power Cable

Date Added: 03/20/2019 by Finn Mölmen, Norway
Just in time for Christmas 2018 I received four LessLoss C-Marc power cables. I used four DFPC's for trade-in, making the investment a treat. I introduced the C-Marc's one at a time in my set-up, exchanging the DFPC's successively, starting with my tube power amp. Immediately I experienced more snap, more weight in bass, better resolution upwards. After an hour or so, something peculiar started happening to the sound; there emerged a quality of flowing, liquid, organic sound that made the music much more appealing, more natural, more like music. This was intriguing, because my setup is rather mature, and I have done my fair bit in power management, using good power and signal cables for quite some time. My first DFPC was nearly ten years old when traded in.
There was no stopping me now: C-marc to the pre-amp, hmm, not easy to detect any immediate changes here, but burn-in must take its time. However, with my Chinook phono-amp improvement was evident rather quickly, yielding more space, more lifelike presence of instruments and voices. Finally, my DAC was favoured with C-Marc power, resulting in more weight, more presence and articulation in the lower midrange, giving pondus to the presentation.
However, I must admit that an objective assessment of the C-Marc power cables has been difficult to carry out, due to the fact that they were implemented in my setup only one month after I received my pair of brand new PMC IB2 SE speakers. Thus I have been witnessing a double burn-in process. The speakers are developing to every satisfaction, and the sound in my listening room are now very lifelike, revealing yet balanced and musical, with realistic dynamics, extremely nuanced and detailed, unerringly placing instruments and voices in three dimensions.
Power cables are among the components in a hifi setup that will perform for indefinite time. The C-Marc's will sit in my setup forever, or until Louis and LessLoss treat us with an even better cable. Over the last year I have experienced the C-Marc's in three different setups. This is a premium performer regardless of price, and at the present price point, the C-Marc power cable is a «no brainer» for anyone considering cables in this price range.
Lucky me, I will shortly be investing in the C-Marc loudspeaker cables for my PMC's now coming of age.
