C-MARC Classic Power Cable

Date Added: 03/05/2025 by Patrice Guenot
This review is about the C-MARC Classic Entropic Process power cable.

Sans LessLoss, impossible de connaître les vrais performances de son installation HiFi, c'est aussi simple que ça!!

Il y a sûrement d'autres concepteurs/fabricant d'accessoires HiFi performants dans toute la production mondiale, MAIS, à mon sens, aucun, qui comme LessLoss suivent la même ligne, le même principe consistant à améliorer systématiquement le résultat sonore vers LA MUSIQUE en elle même, et avec autant de réussite. C'est tout simplement SUPER d'avoir décider d'utiliser ce FIL ROUGE, comme une recette impeccable de cuisine. Je suis cuisinier à la retraite!!

Without LessLoss, it is impossible to know the true performance of your HiFi installation, it's as simple as that!!

There are surely other designers/manufacturers of high-performance HiFi accessories in the entire world production, BUT, in my opinion, none, who like LessLoss follow the same line, the same principle of systematically improving the sound result towards THE MUSIC itself, and with as much success. It is simply SUPER to have decided to use this COMMON THREAD, like an impeccable cooking recipe. I myself am a retired cook!!

Giant Steps

Date Added: 05/04/2025 by Michael Ross
Indeed the Giant Steps do make a very noticeable difference! Some of my thoughts after a week or so of listening. There's much to say here!: 1) I've said before in my reviews of other LessLoss products that what I'm looking for is: "Living Presence" as old record labels, especially Mercury, would say. A sense of being in the room with the performance. Yes indeed, we have more of that. Now! You hear the characteristics more now of the recording venue. Everything becomes that much more lifelike. More of the soundstage, more details of the performance. A fresher, cleaner sound, if I can put it that way. More extra "stuff "has been cleansed from the recording. Fresher, cleaner, more tonal colors, more ease in the movement of the music. I could go on. One final observation: there is a breaking in component of these Giant Steps. First day: nice but subtle changes. Second day - big positive changes! Third day - not so good. What happened? 4th day: OMG - Better than ever! OMG!! So on! Remarkable!

Giant Steps

Date Added: 05/17/2025 by Lars from Denmark
My first impressions on the Giant Steps:


After receiving 25 Giant Steps, i started to listened for half an hour on the existing setup - where I had bindbreakers under my equipment.

– Then I replaced three Bindbreakers with 3 giant Steps under the power supply for my streamer.

The first 5 minutes I heard very airy and a little mysterious sound.. Then suddenly I got a completely new system!

It played with power, dynamics, width, details, depth and an enormous naturalness and musicality I just sat and listened with my mouth open for 3 hours.

I have never heard such a clear improvement in comparison to replacing device feet.

But this was only the first of 8 improvements, because at weekly intervals I placed Giant Steps under my amplifier, then my LessLoss DAC, a LessLoss distributor, a LessLoss Power Base, a LessLoss Speaker Base, under my Ethernet Switch and under a power supply for my Router.

Each time the sound became more organic, natural and magnificent...

I don't understand what Louis has done with this unique combination of materials, magnetism and shape wrapped in such a discreet and beautiful foot!

But even the many and perhaps somewhat magnificent promises I read before the launch were fully achieved.

So now I just ask myself, how many extra feet can I afford to buy? Because I haven't even tried to put 4 feet under each device yet!


Best regards Lars from Denmark

C-MARC Stellar Power Cable

Date Added: 07/23/2025 by Dave Paper
The C-MARC Stellar PC is my first LessLoss product. I've owned many different PCs over the years. Some of them were good and others not so much. This PC is quite different than anything that I've experienced. It just removes noise from my system. Every other PC I've used (e.g., Shunyata, Tara Labs, Crystal Cable, JPS labs, etc.) adds something to the sound. Albeit the other cords I've experienced sound better than stock cords to me. For example, the Crystal Cable I was using before the Stellar was smooth and pretty fluid. However, it was not in the same league as the Stellar. Everything just sounds more natural and real. I love classical music like Mahler. On my (pre-Stellar PC) system, Mahler's symphonies sounded really good. But different types of horns just never sounded real. With the Stellar, a flute sounds like a flute. A clarinet sounds like a clarinet. And so on... Also, drums on all kinds of music sound like real drums. My Stellar PC is still breaking in, but I noticed the difference right away. As the cables continue to break in, everything sounds more natural & real.

It took a bit of adjustment to get used to the Stellar PC because it's hard to know what 'no noise' sounds like. When I listen with the Stellar PC, I'm not thinking about smooth, fluid or even natural (which are all great qualities). I'm just listening to music. I'm adding another Stellar PC and a C-MARC Firewall 640x to my system and I am very excited to see what happens. Icing on the cake is that LessLoss cables are reasonably priced in this crazy expensive audio world we now live in!

As mentioned earlier, with the Stellar PC, instruments sound like they do in real life. I didn't really know that instruments could sound so real! I enjoyed my stereo system and didn't really think about its shortcomings. I just dreamed about audio that I couldn't afford. Now, I'm getting sound that I never imagined I could get out of my existing system with just the addition of a single Stellar PC. I've read a lot of reviews about LessLoss, but I was skeptical. How could my existing system sound REALLY better with just the addition of a single PC? Folks, the Stellar PC works as advertised! I'm going to add new LessLoss products as my budget permits.

C-MARC Stellar loudspeaker cable, stereo pair

Date Added: 07/24/2025 by Mac Finney
To Go Where No Man, or Woman, Has Gone Before...

Holy Crap LessLoss!

My new LL Stellar Speaker Cables & Jumpers are truly mind blowing! I'm hearing micro details like never before. Mids come alive. The REL is taught, fast & nimble. I also have a stereo pair of LL Stellar Firewalls in series on each speaker. Boenicke ComDevs & Stein Speaker Match Sigs are dangling from the bi-posts.

It's difficult to imagine I was able to extract this much more from my rig, but the newly released LL Stellar Speaker Cables have added several more layers of luster to an already shimmering stereo image. It's the difference between a satin finish or piano gloss on your speakers. The newfound depth of the recording is seductive, pulling you further into the performance, taking you to places you've never been before.

Can't wait to turn off the air conditioning here in Baltimore & crank up the tunes. Really nice bump in performance LessLoss!

My fantastic LL Entropic Speaker Cables are wrapped up & ready for return. Make no mistake however, the Entrpoic Speaker Cables performed magnificently. Your generous, convenient trade-in policy is one of the best in the business!

Wonder what Louis Motek will have up his sleeve next?

C-MARC bulk wire and cable

Date Added: 08/07/2025 by Thomas K. Lincoln, NE USA
25.08.25. For Large Grounding Cables with Spades; used as speaker cables: Ordered 2m of these cables, two red and two black for use as speaker cables in a near-field system. They replaced entry-level speaker cables. In A-B comparison using Pink Floyd's Animals (2018 remix) 24/96 CD rip with KEF LS50 Meta speakers: soundstage expanded dramatically, as did three-dimensionality. Localization from speakers greatly reduced. This effect was a no-doubter. More subtle but noticeable: another quintessential layer of grime/haze removed; sounds tightened up a little and became more crystalline. A Gilmour solo became clearer and more sweet-sounding. Subtle tightening of Water's bass. These effects occurred before burn-in. Really looking forward to how these cables will sound in the future! A bargain for budget audiophiles looking for a noticeable upgrade.

C-MARC Stellar loudspeaker cable, stereo pair

Review: Stellar Loudspeaker Cables – A Remarkable Upgrade

After replacing my trusted C-MARC Classic loudspeaker cables and jumpers with the new Stellar loudspeaker cables, the transformation in sound quality was immediately apparent. It’s not just an incremental improvement — it feels like a genuine leap forward in realism, dynamics, and musical presence.

From the first track, I noticed micro-details emerging with unprecedented clarity. The lower midrange gained depth and authority, while bass control tightened significantly. Dynamics have become more expressive, and my KEF Blade loudspeakers have truly come alive in a way I hadn’t experienced before.

After experimenting with connections, the best result came from wiring directly to the HF inputs, with jumpers down to the LF. This configuration opened the soundstage even further, creating a slightly taller and deeper image. The background became noticeably “blacker,” allowing instruments to separate effortlessly within the mix.

Cymbal transients now have a purity and natural shimmer that feel closer to a live performance. Vocals project with greater realism and emotional weight. When listening to Bach, the interplay between violins and cello was breathtaking — expansive, refined, and full of harmonic texture. Trumpets sounded smoother yet more detailed, and the entire musical presentation felt richer, more cohesive, and organically balanced.

Friends who know my system well immediately noticed the improvement. Several remarked that the soundstage seemed lifted higher, and many said they had never heard my setup perform at this level.

In summary, the Stellar loudspeaker cables deliver a profound upgrade in every sonic dimension. The investment is certainly significant, but for the results achieved, I can say without hesitation — worth every cent.

Firewall Module

Date Added: 11/11/2025 
A couple of days ago I installed one of the new Firewall 640x Stellar for power on the linear power supply driving a small LAN to Optical media converter. The media converter sits right after my internet router and drives 30 m optical fiber cable connected to my audio LAN switch.

Tonight, for the first time, I am listening to some music I know well. Although, I know from previous experience that you always bring out amazing products, this new exiting firewall blows my mind! I was just about to upgrade the cables in my subwoofers from hook up wire small to coax, but now I am reluctant to turn of the power as music now flows in a way I have never experienced before🎶🎶🎶🎶. Applauding in your direction 👏. Hopefully it will not be too long before you can produce them in larger quantities.

Oups - another one just slided in on the psu driving my router. More to follow....

Firewall Module

Date Added: 11/23/2025 by Jeff Wolff
I have 4 of the new 640X Stellars in my system and they provide far and away the greatest increase in sound quality I have ever experienced. The bottom line is far greater musical enjoyment, natural tone and better timing and coordination. I am considering upgrading from a company's $7K DAC to their $23K Reference model. If you told me what the Stellars do is the upgrade I would consider it money very well spent. Obviously the Stellars cost a bit less! This is in comparison to the previous 640X Entropics. Best LessLoss product ever and not by a little and that is saying quite a bit.

Firewall 640x Stellar review

"Black Diamonds" with Stellar Performance

I have now been using five Black Diamonds (aka Stellar Firewalls) in my system for quite a while and would like to share some thoughts about them 🙂

I started out with three units, one in front of my LessLoss Distributor (where it replaced a C-MARC 640x Entropic Firewall), one in front of my streamer, and one in front of my DAC/preamp. That setup clearly showed what those black gems do - improved openness, clarity, detailing, soundstage, etc., the C-MARC 640x Entropic Firewall on steroids!

But with only three units, I began wondering if I had them in the right places ...

My "source chain" is completely digital, starting with a standard router (supplied by our internet provider) - well, it's not really that "standard" anymore, as I replaced its switch-mode supply with a good linear power supply that feeds DC to the router via a handmade cable made with LessLoss Large wire. Both the LPSU and the DC cable I made gave substantial sound improvements. The upgrades at the router end were all done quite a while back and were later supplemented with a C-MARC 640x Entropic Firewall and a Prime cable to feed the router LPSU, offering yet another sound improvement.

Next down the line comes my audiophile switch. It has a built-in LPSU and is fed by a C-MARC Classic Entropic power cable and a C-MARC 640x Entropic Firewall.

After the switch comes the Stack Audio Smoothlan Regenerator, which is powered by an external linear power supply. The LPSU is fed from the LessLoss Distributor via a Groneberg Quattro power cable.

At the end of the source chain, I have an Innuos Zen Mk3 streamer (with some modifications, like internal LessLoss Large power wiring). Power to the streamer is coming through a C-MARC Entropic power cable, and (as mentioned above) a 640x Stellar Firewall.

Considering that all the power supply improvements in my "digital" supply chain had given me improvements in sound quality, I started thinking that it might be worth trying out a Stellar Firewall in front of the router's LPSU. But there was a problem. All three Black Diamonds were in use. Also urged on by a friend, who had tried a Stellar Firewall on his own router LPSU, I decided to move the Stellar Firewall on my Distributor to the router LPSU, just plugging the Stellar power cable from my dedicated wall outlet directly into the Distributor instead.

Frankly, because I was removing the Firewall from my Distributor, I was expecting a so-so result from adding a Stellar Firewall to the router LPSU. However, doing this was a marked improvement!

After that improvement, it was clear to me that the so-called "digital" supply chain was much more prone to disturbances on the power side than I had imagined, and I subsequently obtained Stellar Firewalls for both my audiophile switch and the LPSU for my Stack Audio SmoothLAN Regenerator (got one from MusicMagic and one from another friend, who had "overdone" the number of Stellar Firewalls that he needed). Each Stellar Firewall added was a clear improvement (and so was replacing the Groneberg power cable with a C-MARC Classic Entropic power cable 😉).

In my opinion, there are two important takeaways here: 1) The importance of removing disturbances from our "digital" supply chains cannot be overstated, and 2) those Black Diamonds must be as close to each unit as possible for best effect (no news for you on that one 😊).

It should probably also be considered that there are already very capable Firewalls inside the LessLoss Distributor, and that my Distributor also has 8 x BlackGround modules installed.

Keep up the good work!

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.

Louis is one of the best in the business, truly professional and very fast production and delivery. I am very satisfied by your superb service. Many thanks.
