C-MARC Stellar Power Cable

Date Added: 10/24/2023 by Jeff
After many years as an audiophile, I have become cynical about "new and improved". Yes, things are often a bit better, but sometimes it's hard to justify the monetary outlay. These AC cables are a stark exception. Details would only echo the claims made by LessLoss. One to my Power Base, and one to each speaker's woofer amp is transformative. Far more refined with better tone, texture and detail {murmurs that were clearly speech but not clear speech on an intro to a song are now clearly comprehensible} the dynamic envelope is smoother - vocals show voice modulation that just was not there before. A warning re break in: yes, it sounded good on day 7, but on day 9 it sounds way more musical and involving. Now if I can just afford four more...

C-MARC Stellar Power Cable

Date Added: 11/02/2023 by Rainer Weber (Kaiser Acoustics)
Dear all,

since a few weeks I have one LessLoss Stellar power cord in my system.

My system consists of Wadax reference Dac and reference server, an Ypsilon Phaeton Integrated (replacing a Pilium Hercules and Alexander combo) and several Kaiser Kawero speakers.

By the way, I am the designer of the Kaiser Kawero speakers, so listening with several of these models comes as no surprise. See also www.kaiser-acoustics.com

The system runs in a dedicated listening room. Electrical power today is filtered with a Synergistic Research UEF12 filter.

The Stellar power cable feeds now the Ypsilion amp. It replaces there various very expensive power cords from well known brands (cost from 5000€ to 14000€) which I used before.

What to say? First of all there is much more realism and smoothness in the midrange. More texture, more details. But the new amount of information in the records doesn´t come with drawbacks like listening fatigue or harshness.
Second is the control and punch in the bass. More grip, more firm. Excellent!
Treble is more natural and the decay from cymbals or bells are much more realistic.

Soundstage is the first 7 days during burn in more focused to width, after that time depth of stage significantly increases.

Conclusion: One of the best power cords money can buy. An "Über" Reference.

Best regards,

Rainer Weber

C-MARC Stellar Power Cable; Firewall Module; Power Distributor; BlackGround 6x/10x Power Base; BlackGround 8x/10x Speaker Base

Date Added: 01/09/2024 by KH
I have been a supporter and believer of LessLoss product since 2023.

I am currently using BlackGround 10x Power Base, BlackGround 8x Speaker Base, Firewall 640x and also 5 Stellar power cords….

I took the opportunity of the upgrade program to upgrade 5 pcs of Entropic Classic power cords to Stellar.

My setup is streaming based and I was using the Entropic Classic to connect to LessLoss power distributor, streamer, usb regenerator, network switch and 10x Power Base.

When I initially switched from my old power cords to Entropic Classic, the experience was a revelation..the feeling of “live” performance..the background is so quiet yet lively at the same time..the other improvement were increase in depth and width of music..and big reduction in digititis…please note that I am only streaming music through tidal and I am already getting this much of satisfaction.

Now, upgrading from Entropic Classic to Stellar power cord, what I experienced is a definite improvement over Entropic Classic..the improvement I experience in Entropic Classic applies here and are further amplified.. I also experienced increase in dynamics and increase in bass quality and bass output..the increase in bass feels like I have upgraded my amplifier or speaker. What really impress me is on vocal..vocal is much much improved over Entropic Classic..to the point there is really no listening fatigue. The glare that I normally experience in digital setup is gone. Previously there are certain artist which I find it hard to listen to, such as Celine Dion Immortality..i had to lower the volume when the songs reaches chorus/climaxes as its too piercing to my ear.. but with Stellar, I no longer need to lower the volume..in fact, I can increase the volume now and hear even more details than before.

All in all, the upgrade to Stellar was a worthwhile one and I greatly recommend this product.

C-MARC Stellar Power Cable

Date Added: 01/31/2024 by Michael Ross
I recently ordered and received 4 top line C-Marc power cables. To complete my entire power cable system. After about a month of listening, I can report-good things! In a nutshell, the sound is truer to life. Like the old RCA records statement on all its record jackets- "Living Presence". It has greater depth, great room resonance, and a more 'you are there' feeling to it. Just so exhilarating to an audiophile!

C-MARC Stellar Power Cable

Date Added: 02/06/2024 by Joshua J. Wright
The stellar PCs in this review were purchased as upgrades from the Classic ENTROPIC PROCESS PCs.(which are amazing PCs in their own right) The first thing I noticed about the Stellar PCs was how the low level detail was magnified with more weight and density than before. It is like installing an aural magnifying glass making it easier to hear details and dimensionality. Since this effect is produced in such a natural fashion, the end result is total immersion and involvement without any distracting over emphasis in any of the frequency extremes. This greater magnification in both macro and micro domaines creates a more expansive and 3 dimensional sound field. There is a greater sense of unforced ease while at the same time exposing more musical information. Low level listening is more satisfying while turning up the volume becomes even more rewarding. Each listening session becomes a never ending journey, extending itself for no other reason than the pure joy of musical connection and discovery. Prior to the addition of the Stellar PCs the sound was what I thought to be amazing, but has now taken on a what could be described as a more mature and insightful nature. The Stellar power cords are in a word, EXTRAORDINARY!!! Despite thinking the sound of my system had already reached its pinnacle, I was happily proved wrong once again.


Be prepared to tolerate a full 7 days of break in before having the full experience. It is more than worth the Wait. Once you hear it you will be spoiled for life.

C-MARC Stellar Power Cable

Date Added: 02/07/2024 by Maarten
Crispy, full, clear, well-balanced and a tremendous pronunciation. These words first came up to me, after using the C-Marc Stellar. In combination with the 640k firewall.
My Naim NSC222 really performs better, brighter and cleaner.
Naim has an external power source NPX 300. I tried this for a week.
To be honest, the Stellar and the 640k together are in the same league as the NPX of 7.000 euro.
A no-brainer in my opinion.

C-MARC Stellar Power Cable

Date Added: 03/03/2024 by Sven Palvig
At last, my four LessLoss Stellar Entropic cables were delivered.
I have waited impatiently with the silver lining of practicing patience.
It takes 30 hours to produce a LessLoss Stellar Entropic cable of two meters. However, the cables are completely raw, and they have to be adapted through playing music, but that is part of the experience: Experiencing how the cables evolve with music - what a pleasure!
New details emerge from familiar music. Amazing!
I am thrilled and amazed at how it can improve the sound. This is astounding to me!
I had absolutely amazing sound before, but with these power cables both the cheap Prime and their top cable Stellar Entropic, just so much has happened! There's simply more to it all!
The music is opened up even more. Now, it’s real music. To the ear it’s real, live music.
LessLoss produces less noise. Less noise means a better chance for the devices to deliver exactly what they were built for. It’s a win-win. LessLoss means less loss. Less lost music! It makes you listen to the music more carefully. For example, listening to the Danish song “Den Lige Vej” with Kim Larsen sounds like the singer is right there in front of you singing live. Even the smallest mouth movements are now heard much better and more naturally.
I have also tested the cables with choral music: Himmelrand SACD from 2L. Great recording! With my old system, I could more or less pinpoint the individual singers, and I still can. But now, I can hear them standing up and singing naturally. The choir is singing here at its natural height, wide and deep.
Sounds in the background appear as well. Low sounds from drums far back, don’t drown out anymore. I hear the different touches of the drums. It is excellent! With a singer like Mari Boine Persen in "Eg veit i himmerik ei borg", you hear how her voice is graduated with detail, getting weaker and weaker until it’s silent.
You experience the silence in the room. This is huge! It is transformative! Silence in the music means more calmness, and the music becomes far more stress relieving.
Music can be wild, and Stellar Entropic allows it to be! With Stellar Entropic, there is dynamism, it’s terrific! With Stellar Entropic, there is silence in the music! When brass cymbals are struck, they sound metallic, as they should be! The treble is so clean and detailed! With drums, you hear the drum skin and the bang!
You experience things in the background where people are talking.
With Stellar Entropic, you can experience more of what LessLoss Prime provides. It’s what Bindbreaker also does, just far more!
Thank you for reading my experiences so far! I’ve had help with the translation to English, so please excuse any typos. There’s probably lots that I’ve forgotten to write here, so I may add more when I experience these cables further.
Thanks to Renè and Henrik for introducing me to LessLoss cables! My system has moved from awesome sound to even more lively and natural sound. With more wildness, dynamics and silence! These cables opened up the music so that my room appears bigger and deeper!

C-MARC Stellar Power Cable

Date Added: 03/25/2024 by Ken Sternberg
Everything I have liked about your Entropic Classic power cords is improved, particularly the lowered noise floor after the groaning ended upon completion of the prolonged struggle in close quarters removing all six Classics and replacing them with the Stellars ;-)

I agree with the user review comments of your other customers.
I could hear the improvements immediately.

Music first listened to …

“The Great Ray Charles” Atlantic SD-1259

The Ray Charles/Quincy Jones track “Undecided” is “rockin”.
There’s terrific drive I had not heard previously, & there’s great pace, fast transients, and the ambience/reverb of the double bass accompanying everyone is more noticeable. The tenor & baritone saxes, and muted and open trumpet are really live sounding, dynamic, with just beautiful tone.

A old standby recording that I’ve always gone back to listen to is Ben Webster’s “At The Renaissance”, when accessing system changes.

Here are a few observations I made in the first moments after installing the Stellars:

I think these power cords are bringing more presence & details into focus… the lows deeper, with spacial information definitely more discernible -
The audience clapping during “Georgia On My Mind” sounds like it in a different place than the musicians. Chattering of the players is heard better now.
The music’s more visceral, with quieter background.
Rowles’ piano tone is spot on.
Butler’s drum skins’ tone, and the irregular “off” or “accent” beats of his sticks on the cymbals, are just better. Jim Hall’s guitar’s bell tones float lightly above everything.

Good move, definitely, especially if things are going to get better from here on in!

I’m excited about hosting our Philadelphia Audio Group this September, and I will certainly encourage anyone interested in why everything is sounding so good to check out your website - particularly the video you recommend, and the “Best Steps Forward” article.

All the best!

C-MARC Stellar Power Cable

Date Added: 03/25/2024 by Michael Ross
I’ve had the the latest group of 4 C-MARC Stellar power cables for over a month now. Upgraded them all about 6 weeks ago. (Now, all my cables are the high end Stellar C-MARCs). Just thought I’d drop you my brief impressions after careful listening. 1) I’m delighted! 2) The thing that stands out is the sense of "being there”. Was it the old RCA records would advertise themselves as having “Living Presence”? That’s what I now have! A significant upgrade! I’m sure that if I were to go back to mu old cables (which I sent back to you) I’d immediately notice the difference! For the worst! Everything just seems more real, more live, and richer. Listening to the orchestral Debussy, for example, is a real treat! The textures are are richer, cleaner, and more detailed.

Stellar power cord: Call me » Impressed «

I have done a couple of listening sessions with this new power cord (replacing a C-MARC Classic Entropic) on the power supply feeding my Totaldac D1 DAC and Reclocker. The Stellar has run only 6 hours and the result are already very good.

This afternoon I went back to the Entropic to check… and ensure my ears are not lying to me. The progress bringing in musicality by the Stellar is quite significant; I did not expect that much more improvement.

What I do hear is more body in the music, a nicer and more detailed top end, a more articulate bottom, and overall a better top to bottom balance. All that gives more life to the music!

You are right: attention to the power side of our equipment is absolutely critical.

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.
