Introducing C-MARC™. A new generation of high-performance wire and cable, well equipped to deal with todays over polluted electromagnetic environment.

C-MARC™ is a new type of Litz wire. C-MARC’s noise reduction is based on the bucking coil method using two counter-polarised coils. Every strand's clockwise turn aligns with a corresponding counter clockwise turn of precisely mirrored diameter and step. The two, resulting counter-polarised coils are mutually superposed. A second-scale fractal replication of the already bucking coils is then repeated. Through electrical cancellation of the induced noise, C-MARC™ provides an enormous signal-to-noise ratio in today's demanding audio environment.

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. Michael Ross, Southfield Michigan
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! -Ken Sternberg
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! Sven Palvig, Denmark
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.
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.
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!
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 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 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.
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 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
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...

Entropic Process: A LessLoss technology most profound

Pictured below is the new insignia of the ultimate LessLoss achievement. When you see this symbol, you can rest assured that sonics don't get any better than this!

We have been investigating the mysterious burn-in phenomena for the past 20 years, following it very closely and learning ever more about it. Finally, we have figured out a way to actually use it in the design of an actual product. This has been on our creative minds ever since day one when we first experienced burn-in decades ago. But the secret within has remained elusive to us—until now!

This does not mean we have abolished all initial changes in sound quality. It only means we have developed the means and methods to accelerate it—pre-prime it, so to speak—to the point where, in your first two weeks of listening, you might go through some 200 years of regular burn-in. The burn-in process has not been disposed of by us but rather put into overdrive in order to serve listeners even better! This is the genius of our new Entropic Process.

To fully comprehend the concept behind it, prerequisites are in order.

If you have never experienced any strange burn-in effects…you will not yet know that of which we speak. The strange burn-in effect remains, undoubtedly, the most mysterious of all aspects involved in high-end audio. Appreciated, experienced, and accepted by thousands, yet understood by none, it remains an uncracked code of mystery which has represented a strange bottleneck to designers until now. Sometimes it is a cause of ridicule, but sooner or later everyone experiences it…and suddenly that voice of ridicule is noticeably quiet.

What is burn-in?

Burn-in is a strange phenomenon in which newly made gear or cables go through a series of inexplicable initial transitional phases in terms of performance. One day the sound may be brittle and coarse; another day the sound may be rubbery and elastic. One may experience phases of bass-heavy submersion as if one is under water, then periods where one feels the bass is too weak or not in balance with the mids and treble. Eventually, these two extremes converge into a balanced, stable performance, a mature and pleasant tonal balance.

This process is dependent on two things.

First, much depends on total system transparency. If the system has deep flaws, such as being located in a room with ceramic tiles and many exposed glass windows, of course an acoustic echo chamber like that will mask such effects greatly. However, if the system is set up well in an acoustically well-organized space, you'll hear the flaws with ease.

Secondly, it depends on how sonically neutral the fresh product actually is. If it is severely skewed in some arbitrary tonal direction, it will be more difficult to sense just what is going on in terms of this burn-in process. An example of this is found in multi-strand copper conductors with silver plating. But if a product is a sonic giant in terms of its ability to present exactly what is taking place in the recording, without editorialising, one will hear huge burn-in swings initially.

It is most likely that LessLoss products present exactly the same changes that any new wire goes through. The only difference is that C-MARC has such a fantastically low noise floor that one can more readily perceive and experience these large burn-in swings because so much more detail is exposed to the listener than usual. It goes without saying that you simply cannot have it both ways: you cannot expect a totally transparent cable to reveal real data on a recording that won't simultaneously also reveal a much deeper underlying physical aspect of burn-in as it matures and settles in performance. The performance is the ability to show more and more minute changes in signal. This also must mean, at the same time, that it will show more and more minute changes in whatever actually constitutes burn-in (molecular structure re-alignment or something…? sorry, we haven’t solved everything!).

And a mystery it is and remains.

But we have made a HUGE step in accelerating it.

If, before, you experienced the infamous ‘roller-coaster ride’ of settling and opening up, now it will be a supersonic rocket launch with G-forces you had better be prepared for. After the rattling of instruments, mind, muscle and bone, the view, once in orbit, of that rarefied silent cosmos, is really worth the patience. Burn-in time is not necessarily longer or shorter…it is just more intense.

Both the C-MARC™ power cable and C-MARC™ Entropic Process power cables are superb performers. It takes us 18 hours to make the C-MARC™ power cable and no less than 30 hours to make the Entropic Process version.

Branding labels from now on

To avoid any confusion, from now on, all C-MARC™ power cables come with labels clearly denoting the model type attached to the plugs. These are applied to the inner walls of the transparent plugs, so they will never rub off, even with rough use, for example in the context of a live traveling stage band setting.


C-MARC™ stands for Common-Mode Auto-Rejecting Cable.

C-MARC™ is unlike any other hook-up wire or cable currently produced. It is based on the bucking coil method of noise reduction, used most famously in twin coil pickup designs first developed in the mid-1930s to silence hum from electric guitars.

This type of guitar pickup was called ‘the humbucker’ because it 'bucks the hum', i.e., noise, out of the desired guitar signal through phase cancellation of two counter-polarised inductors. When the inductors both induce a common signal, it is induced in opposite polarities by each coil. These opposite polarities then mutually cancel when the two counter-polarised noise currents are combined through simple electrical summation. Humbucking coils are also used in some microphone designs, as well as in sensitive sensor technology where induced stray noise is not acceptable and the highest signal-to-noise ratio is desired.

LessLoss designs a new type of wire around the humbucking principle.

C-MARC™ wire is a special type of Litz wire. It features all of the known benefits of traditional Litz wire, but without the disadvantage of being formed as an elongated coil (inductor).

Traditional Litz wire has the following advantages over normal 'naked' multi-stranded wire and solid core wire:
  • Litz wire has a greater ratio of surface area to cross sectional area, resulting in less phase smearing between lower and higher frequencies.
  • Litz wire creates no distortions due to so-called “strand jumping” or diode effects resulting from loosely contacting oxide layers of adjacent naked strands.
  • Litz wire is more flexible, practical, and safer than solid core wire of the same large cross-sectional area.
C-MARC™ wire shares all of the above advantages of traditional Litz wire and advances the art with these additional unique benefits:

(1) Traditional Litz wire is bunched and then twisted in only one direction, leading to the formation an elongated group of uni-directional coils (inductors) of differing diameters, its structure resembling elongated overstretched springs of different sizes.

[Fig. 1.: Sketch of typical Litz structure where multiple coil diameters and single coil turn direction resemble several overstretched springs bunched together. This structure allows high speed of production.]

[Fig. 2.: Each long separately insulated Litz wire can be seen as a separate coil of a given diameter and step. The different diameters are a result of the bunching before mutual twisting.]

[Fig. 3.: Individual wires of differing thicknesses are bunched together to form different geometries. Many variations of the Litz structure exist, most of which are based on the main idea of first bunching and then twisting into spirals.]

[Fig. 4.: Some manufacturers offer braided Litz wire, so-called “Type 7” Litz. This wire also is formed from initially bunched and mutually twisted strands before braiding. This type of wire is compressed after braiding the twisted bunches into an overall rectangular shape before tape wrapping and over-extrusion.]

How C-MARC™ is profoundly different

In contrast, C-MARC™ wire goes down to the very fundamentals in a completely mirrored, balanced geometry. It aligns every Litz strand's clockwise turn with a corresponding counter clockwise turn of exactly mirrored diameter and step along the length of the wire. These two resulting spirals are mutually superposed in counter-braided fashion. Noise is thus induced in exactly opposite polarities and in exactly mirrored amplitudes, while the good signal is common to both spirals. The two counter-polarised noise signals mutually cancel when the two counter-polarised currents are combined through simple electrical contact at both ends of the wire. Thus, through auto-rejection of opposing electrical phase through summation at the ends, C-MARC™ wire perfectly counters the noise induction, whether from external sources or self-induced, which normally pollutes every other twisted Litz wire assembly. In this way, C-MARC™ wire achieves signal transfer which is corrupted substantially less than the industry has been able to achieve through other means.

[Fig. 5.: C-MARC™ Litz schematic layout. The clockwise and counter clockwise spirals are mirrored in diameter, step and wire gauge, while at the same time superposed in relation to one another. This results in opposite phase induction within the very structure of a single polarity line. While production speed is substantially slower, the silence of operation of C-MARC™ wire is far superior to standard Litz structures.]

(2) This is not all! LessLoss C-MARC™ wire features two-scale ‘fractal’ replication of the aforementioned mutually superposed counter-twisted layout. This mirrored and nested structure further enhances the mutual cancellation of counter-polarised inductive twists, while at the same time allowing enlarged overall cable cross-sectional designs which serve to further lower resistance without any sacrifice of signal fidelity or flexibility.

[Fig. 6.: C-MARC™ shown in two-scale fractal replication. Everything that occurs geometrically at the core level is repeated again at the larger level, thus further reducing the induction of noise. Just as the initial clockwise and counter clockwise spirals are mirrored in diameter, step, and wire gauge, while at the same time superposed in relation to one another, so too at the larger level. This makes the cable a silent performer without influencing the natural tone colour of sensitive signals throughout the frequency spectrum.]

What this means

C-MARC™ is intrinsically the most silent wire on the planet and provides pure transmission of signal. The degree of silence of the working solution is in direct proportion to the degree of superposition of the counter-polarised twists, as well as in the degree of their mirrored equality in terms of turn radius, step, and resistance. The idea being that in the best of worlds, both opposite ‘polarities’ of a single lead of C-MARC™ wire induce the exact same noise, and a perfect summation to zero will result at both ends of the line.

(3) Because the individual enamelled wires which make up the unique Litz structure of the C-MARC™ wire are so small in diameter (0.125mm), the ratio between total surface area and total cross section is further enlarged for an even better phase relationship across the entire spectrum.

(4) This structure further enhances flexibility and ease of bed on any axis, especially for large cross-sectional cables, without unnecessarily enlarging the entire cable assembly.

(5) The strands used in C-MARC™ wire are covered with the thinnest technically possible colourless enamel. They are solderable once tinned in a soldering pot.

(6) There is no plastic at all; instead, C-MARC™ wire and cables are insulated with tightly braided, 100% natural, gassed, and macerated cotton fibre with double coverage for added protection. This results in a very lightweight, highly flexible, natural-sounding product with today's best performance characteristics for delicate audio applications with an enormous signal-to-noise ratio.

What can I expect in terms of sound?

Well, you won't hear coloration, that's for sure. You will however hear a lot more of the music's expression and true content. Click here for a bunch of reviews which will show you how various people in the press and users have expressed what they have discovered using C-MARC™!

How does the new C-MARC™ Cable compare to the DFPC Reference?

The tonal character of C-MARC™ more liquid and fluid, and it resolves more detail from any recording. As good as the DFPC Reference is, it is still made of plastic (albeit very high-quality plastic with excellent characteristics). Over and above the improvement in the C-MARC™ power cord in that it is made entirely of cotton and a very thin layer of clear lacquer instead of plastic, the extremely well-balanced counter-polarised coil technique lowers the noise floor even further than the very effective Skin-filtering employed in the DFPC Reference. The overall result is one of both lowered noise and greater tonal character. It is very easy to recognise these improvements straight from the start, even without burn-in.

Another improvement is found in the connectors. In C-MARC™ they are not made of brass but rather pure copper. And, instead of glass filler in the black plastic of the housing, entirely clear and extremely stable plastic is used. If that weren't enough, these connectors are cryogenically treated, whereas the 079s are not.

All of these improvements add up to obviously superior results from the outset. After about fourteen days of settling, the sound quality becomes even more organic and lifelike. We are confident that C-MARC™ is here to stay and that, after a few more years, it will be recognised and employed in many different manufacturers' loudspeakers and equipment as internal hook-up wire.

One further advantage of C-MARC™ over the DFPC Reference is its extreme flexibility and light weight. Thus, even the most sensitively placed lightweight gear has the very best conditions to maintain the fine vibration control of even the most delicately positioned special tuning feet. See the following image for an idea of C-MARC™ cable's flexibility.

Special custom plugs are available.

If you need a custom plug on your C-MARC™ power cord, simply inquire. We can make them with high-performance UK-type plugs from Furutech, AU/NZ type plugs from Furutech and 32A PowerCon type plugs from Neutrik. 20A C19 plugs can also be implemented.
