Firewall Module; C-MARC Classic Power Cable








Before I get into how the custom Lessloss power distribution unit sounds like, let's get into the specifications:
- Chassis mostly made out of 1 1/2" thick oak-wood
- Two thick slabs of panzerholz plywood(to bolt/glue the inlet/outlets into it)
- 1 IeGo AC-01 BK(Cu-Au) inlet
- 4 Furutech GTX-S NCF(R) outlets
- Polished and grounded(with large internal hookup wire) copper shields around the inlet and outlets
- All Lessloss c-marc triaxial internal wiring
- 12 firewall 64x units
After connecting a super c-marc power cable from the power outlet to the inlet of the distribution unit and four connecting from the power distribution unit to the PC, the XMC-1 processor and the two benchmark AHB2 amplifiers I fired up the equipment to hear how it would sound. When I started to play some music, I immediately heard the purist, most calm, pleasant and mesmerizing sound coming out of a black hole of complete silence as there was absolutely no sibilant in the sound with just empty space between each note. It's as if a very thick and abrasive blanket of static colored steel wool(called RF) has been taken out of the sound which imparted a brittle, dry and closed/collapsed sound that always bites into your ears but is now unbelievably smooth and liquid that flows out of the speakers like water. The sound-stage, at this point, is completely open and holographic, with each sound, not artificially laser-etched into the sound-stage, but effortlessly floating in mid-air separate from other sounds much like in reality. Instead of having a sound that is resolutely and tonally masked, uninteresting/bland and lifeless because of the blanket of steel wool, the sound is extremely vivid, revealing the finest detail, nuances and colors. The sound is much more tangible, defined, rich and full transporting you to the venue where the artist is singing. The attacks have plenty of contrast and inter-lapping of decay from various instruments are easily heard. The resolution and smoothness go hand-in-hand creating a sound that is not smooth but dark, or resolute but cold/analytical, but a sound that is just right. As far as color/timbre/tonality is concerned, each individual sound is vibrantly painted with many various shades of organic colors as if rainbows are bursting forth from my speakers, that especially make acoustic instruments sound very authentic and real. Electric guitars and electronic music aren't quite as tonally rich although they also do have a certain tone to them. I'd also like to make a quick mention of my experience of re-playing Alan Wake after adding this unit to my system. If you've ever played Alan Wake, you know that it's not necessarily a terrifying horror game, although it most certainly does have an eerie, moody and dark atmosphere to it. After adding this unit to my system, playing the game was much more entertaining, vivid, engaging and well, eerie. I really felt the game's dark atmosphere coming alive in the room as I ran across Bright Falls in the night, going from mission to mission. After owning this Legendary product for a few months I can most certainly say that there are very few words that can describe this unit's performance. It is truly in a class of its own.
In conclusion, I would have to say that this unit really reveals the soul of the music. It eliminates other-worldy amounts of RF and leaves you with a high resolution, vivid, organic, beautiful, confident, expressive, holographic and rich sound that has plenty of definition. You are left with living music.
Thank you Louis and Lessloss team for building the crown jewel of my audio system! This unit has taken my system much closer to the peak of mount Everest!

Just received the distributor today. Almost had to ask how to get it out of the perfectly made box :)
It looks way better in real life as I thought, and I see, that you intentionally rounded the edges on each part, which I misinterpreted on the pictures.
The color fits nicely into the room and it looks impressive overall. Moved it behind the rack though after the first few songs and knowing, I will never turn back.
What can I say … bass again deeper, stronger and better controlled. Richer colors and textures, more "organic". More consistent and coherent sound sources of all kinds. And more palpable. I almost tried to grab a harmonica. And all this within less than an two hours after plug-in.
Unfortunately, you did not send any instructions … So, how can I get rid of the musicians in my room. They won’t leave even after finishing their songs :)
Louis, chapeau!!!!
Thanks for this wonderful device (is this just a device???) and thank you too for your patience with me.
It was a lot of fun to chat with you, and I hope, I did not get on your nerves too much.
My review for publishing has to wait until later, after a little more burn-in.
Thanks again and have a great weekend,
Joerg

After a long train ride, I finally got to enjoy the stereo and "THE DISTRIBUTOR”.
Surprise … my stereo sounds so much more natural after 5x24/7 :):):)
Thank you so much for your inventions wrapped into such an entertaining social connection !!!!
---
Just listening while I type this … wonderfully rich, powerful and smooth at the same time, just making me happy !!!
Have a great weekend!

Wow, burn-in milestone … sibilance finally down a lot, which was my biggest challenge since ever I started my digital only stereo. All is rich and has a body, bass finally punches. Thanks so much for this wonderful device!!!
What possibly can the cable add to this :)
Best regards
Joerg

The Black Eyes Peas “Elephunk” (Hip-Hop) never sounded so good with clear and rich voices and slamming punchy bass driving it, WOW WOW WOW, very cool.
Not a real Hip-Hop fan, but this one gets played sometimes

Great chance today to get a second opinion.
My stepson was over with his family. He is a professional flamenco guitar player and has a widespread taste for all kinds of music.
We send all females out of the room ...
Then, I asked him to choose music, that he remembered on my stereo … without telling him the reason.
He came up with Mr. Bungle, some very extraordinary experimental rock band with interesting sounds and good recording. We didn't play it recently, but it was obvious, when the first bass sounds came in and he had to smile. This was not possible before, especially now with feeling the bass with your body. The next thing he could describe, was the way better separation of instruments and voices. He agreed to more natural sounds as well. And he continued with other songs and later with other bands. We cranked it up very high and had so much fun !!
Will be hard to wait for the other cables :)
Thanks again Louis!!

Just had a wonderful listening of my stereo. Unbelievable what happened after my last email. Since last Wednesday, the voices are considerably improving, standing out more with more texture and details … and less sibilance. The remaining sibilance is closer coupled to the rest of the voice and sounds more like real. The stage takes the entire room, at least ahead of me, with even more space between the instruments. Was it the C-MARC power cable or the distributor?? Probably teamwork :)
And yes, terrible burn-in days before with different surprises like flat stage, dull voices, resonances … But I know this for quite some time, not only with your products :)

Put simply, giant speakers in a tiny room completely disappear and I am in the music, a part of the music.
Thanks for all you do.
Firewall Module
So when for the first time (oct. '18) I added a Firewall 64X to my C.E.C. transport I was astonished that there could be such an improvement in 3D performance, quietness around voices and instruments, an even more tightened expression of the mid-lows and lows etc etc. Because spaciousness, clear definition and separation of instruments in highend reproduction is what I like I thought I had reached that already quite well in my system. But indeed.... it did become better with the Firewall 64X. Immediately I regretted not to have ordered more Firewalls for this attractive earlybird price.
However half a year later there was this upgrade version of the Firewall: the C-Marc Firewall 64X and indeed again with earlybird special prices. So in june '19 I received a package with 5 of the new Firewalls. Systematically I
-first replaced the CD-transport Firewall for the new one: no doubt about it, still more improvement in the qualities I described before.
-then I daisy-chained 3 of the new Firewalls before the power distribution as advised in some reviews. I was not happy with that solution: although very airy I experienced the overall sound as "lost in control", "disorderly".
-then succesively I added a new Firewall to my tube DAC, the tube pre-amp, both the tube monoblocks and everyone of these steps meant a further improvement in highend quality of my system, the 2nd to 5th step maybe not as overwhelming as the first one, but clearly observable.
Now about 6 weeks after first implementation of the new Firewalls it's still getting better especially in definition and quiteness which for some probably sounds odd but which means that there is no "smearing" of other noises around the instruments/voices you like to hear.
Non-audiophiles will probably say: but it's about the music. We audiophiles know that perfect reproduction of this same music let you enjoy this same music so much more. These Firewalls mean a large step into the direction to the perfect sound.
P.S.: In recent years I sometimes thought about changing my powercables. You can understand I stopped thinking about that now....

For those for whom some more detail might be of interest — I currently have three high end systems, each with a different character. Over the years, I have seriously listened to a dozen different brands of cabling and power conditioning at a range of price points commensurate with the level of investment in each overall system. Virtually all sets of cables were above the price of a full C-MARC set -- at times many multiples above. Each set of cables had pros and cons and some stayed in each system and when they did, it would be the full set of cables for coherence. Often moving from one set cables to another in each system usually changed one or two aspects of the presentation of the music. At times, while there was shift, the "net" result was not an improvement in my judgement. Other times, there was a "net" improvement but there remained a weakness in some aspect. The "best" cabling in my judgement lowers the noise floor of the system and "stays out" of the way as much as possible.
In many circumstances, the specific character of a set of cables can be used to compensate for the opposite characteristics the components possess. For example, "bright" cabling can compensate for a "dark" set of components. In my experience, this approach always leaves a sub-optimal net result but may be the most practical approach given the components in question. C-MARC’s character is neutral and I could not discern any particular emphasis the cables brought — they were not brighter or darker; they didn’t accentuate one part of the recording over the others; they did not appear to be faster or slower than other cables etc. Their main effect was to increase the effortlessness and fluidity of the music while improving the coherence and size of the soundstage. Imagine a sort of haze around the band or orchestra members that other cables impart or allow — C-MARC simply eliminated the haze (and occasional harness around some highs). In this sense, I believe C-MARC is likely eliminating various types of noise and interference present within and among the components of the system, letting each play its role in the music delivery with minimal negative artifacts introduced. The net result was a notable increase in musicality and engagement with the music.
For anyone considering C-MARC one step at a time, my suggestion would be to start with either speaker cables or power cords. If it is possible to audition the whole set, even if finances may preclude the purchase of a whole set at once, I would recommend doing so, so that the full potential of the system in question can be heard with comprehensive C-MARC cabling.
For any skeptics reading this, I had no interest in changing the cabling in any of my systems which were all performing well. Konstantin at Atelier 13 in Nashville offered to send me a C-MARC set at his expense just to see what I thought. In the end, the overall effect was so profound I purchased the full set — they were that good. At the C-MARC price level, and at many price levels above, I have not found a better set of cabling that works equally well with tubes and solid-state, high efficiency horns and low efficiency two-way etc. C-MARC lets the inherent quality of whatever you have shine through to its fullest.

I wanted the best-sounding cables I could afford, and I wanted to stick with one manufacturer. I decided to try LessLoss’s C-Marc cables because they were priced sensibly, a US dealer had strongly recommended them, the online reviews were positive, and they were easy to handle (i.e., highly flexible). The actual technology is beyond me, but the LessLoss website is exhaustive, for those who want or need to know about those things.
I’ve been following a series of steps:
Step one: new signal cables.
This meant two 1-metre C-Marc interconnects (RCA) and a pair of 2-metre C-Marc speaker cables.The improvement I got from the C-Marc’s was what Louis, and the reviews, told me to expect — more relaxed, liquid, with less grain than I’d been hearing before and also less congestion between notes. Changes in a stereo system tend to show up most obviously in the bass, and regarding that, bass went lower and cleaner, which is what I wanted and hoped for. Overall, C-Marcs were an obvious though not huge improvement.
Step two: Two C-Marc power cords.
I plugged these into my monoblocks. What I heard, after break-in, was the same as what I heard from the signal cables, but much more of it. I mean MUCH more. My system had already been doing well at filling in between the speakers. Now, between the speakers, the blackness between the notes was even blacker. That erased almost all cloudiness and made for much improved separation between instruments and between instrumental lines. All the while, the sound stayed relaxed. When I played rock’n’roll, the system kept up with it — drums sounded explosive, bass went deeper and cleaner but also was rich in overtones. Treble was highly detailed but never shrill. Louis had told me to expect this — that good sound starts at the wall, which means that the power cables are the foundation of his product line.
Step three: LessLoss Bindbreakers.
I was impressed enough by the cables that I thought I would try his Bindbreaker isolation devices. The obvious place to start with them was under the Placette RVCs, which still rested on the sorbothane nubs that they had come with. They made an immediate and huge improvement. Basically, they added more of what the cables had added but also expanded the soundstage into the corners of the room behind the speakers. There was correspondingly more space between the notes and each note has more weight to it. Pace, rhythm, and timing all improved. The expansion of the soundstage behind the speakers was the biggest shock so far when using LessLoss products. Even my wife noticed — “Matthew, what did you just do!?!?!?” Around here, that’s the ultimate test.
Step four: More Bindbreakers.
This time I placed them under the amps and server. I got more of what step three got me, which is what I’d hoped. Again, the improvement was obvious, and along the lines of step three had done, but more of it, though really, the jaw-dropping moment had been when I first put them under the Placettes.
Step five: Still more Bindbreakers.
I wondered what they would do under my speakers, so, two more sets of Bindbreakers. This is where things got fraught for a while. With them under the speakers, the soundstage expanded well out toward the listening chair, which was wonderful. BUT ... the sound also grew more congested, as if all the notes had got wrapped in fog. The expanded soundstage was a definite plus, but unless I could eliminate the fog, I couldn’t leave these in the system.
So I tried two things: (1) Review the speaker placement. That helped, even moving them an inch did that, but not enough. Some of the cloudiness dissipated, but not enough, and bass still sounded muffled. So, (2) I adjusted the settings on my Lumin server. Specifically, after a few tries, I ended up turning off all upsampling/resampling, switching everything to Native, and then turned on DSD. Doing that basically solved the problems that the speakers had first encountered with the BB’s (cloudiness), without weakening the strengths (a much expanded soundstage, a very natural, liquid sound, a wonderful combination of weight and air).
Good cables make a difference, and C-Marc’s are emphatically good ones. In the same vein, the Bindbreakers are the best isolation devices I’ve ever had in my system (and previous to this, I’d been using a series of highly regarded ones).
LessLoss builds some amazing gear. And I haven’t even tried their Firewall technology yet. Will be saving for that.
Some general notes:
The cables take a long time to break in, and even once they’re broken in, they react more to the weather and to time-of-day issues than most cables. Live with it ... when they’re at their best, which is almost always, they’re amazing.
I demagnetize my system more than I used to with these cables. Specifically, I do it every four or five days instead of every three weeks. These cables seem to benefit from that.
Once you’ve installed these cables, don’t move them or even touch them. They’re sensitive to that. So are all cables, to a degree, but these more than most.
Good audio starts at the wall. Get a high-end receptacle, if you want to do justice to these cables. Even the very best ones don’t cost that much.
The Bindbreakers require break-in as well – a few days, at least. Strange but true. Perhaps because they are partly made of wood.
When you change your cables, you’re changing the signal the speakers are receiving, so adjust your speaker placement once the C-Marc cables have broken in. It always helps.

Specs as follow:
- LessLoss custom FW module (custom 4-unit long 64X)
- LessLoss C-MARC cabling throughout
- Oyaide R0 receptacles
- Oyaide WPC-Z aluminum mounting frames with carbon fiber plates
- Box construction: 1.1" thick cherry wood, glue assembled, rounded corners and clear lacquer finish
- Outside box dimensions: 12.6" long x 7" wide x 7" tall
The box is just long enough to accommodate the 4-64X module, power inlet and cable bends.
The box could have been a couple of inches shorter in height and a tad narrower, but I wanted it to have some extra clearance inside for cable bends and potential future modifications, and I wanted the box to have some extra mass for vibration absorption and stability.The bottom of the box has a 1.1" thick removable panel that also solidly supports the FW module.
Thank you for all your advice and for providing the custom four-unit-long FW and pre-attached C-MARC cabling. It will take a while to burn-in. I look forward to its utility in my system.
Update Sept. 1, 2019:
Today after checking all the receptacles with a plug checker and getting a green light on all, I connected the distributor to the wall receptacle with a C-MARC Power Cable and plugged in my audio gear. When I turned everything on the first thing I noticed was that I could no longer hear the slight hiss that I used to hear standing a few inches in front of my loudspeakers. It wasn't bad before, but I didn't expect such silence. I had to look at my amplifier to be sure the tubes were glowing. From the listening position the sound seems a tad cleaner and the bass a little stronger than before. Those are my first impressions on first listen without any burn-in. I believe the reduction in audible noise at the speaker driver face is evidence that the 4-64X FW module is doing something positive in my system. I already had standalone 64X FW modules at each component power inlet (and still do), so the added quadruple 64X power distributor with its high-grade components, made a discernible difference in my system.
