C-MARC XLR balanced signal cable, stereo pair; C-MARC bulk wire and cable

Date Added: 12/03/2019 by Vladimír Bartoš
Dear Louis Motek,
I found your business looking for the right cables for my sound system. Because I wasn't happy with my previous "Wireworld" cables. This weekend, I made three pairs of symmetrical signal cables using the C-MARC ™ cable provided by you. At the end we tested them with a friend. Improvements were bigger than I expected, every time. It has significantly improved the space for the deployment of instruments in the sides, also in the front. That's why I decided to replace the other signal cables as well as the power mains throughout my assembly after studying your LessLoss page.
Thank you for the excellent ideas you have for improving sound reproduction. I look forward to further cooperation.

C-MARC bulk wire and cable

Date Added: 02/14/2020 by Nik
Ich habe meine "WireWorld Mini-Eclipse 7 LS-Kabel" durch C-MARC Exemplare ersetzt. Am meisten beeindruckt, dass S-Laute entschärft werden - ja durch das Lautsprecherkabel! Wenn man zum Beispiel das Pfeiffen von Livingston Taylor bei seinem Song "Isn't she lovely" hört, so war das mit den alten Kabeln ein schneidender, im Ohr fast schmerzhaft klingender Ton. Durch die LessLoss Kabel ist die unangenehme Komponente komplett verschwunden und das Pfeiffen klingt wunderbar natürlich. Interessant ist außerdem, dass der Bass jetzt deutlich tiefer runtergeht und - trotz Röhrenendstufen - deutlich druckvoller und strukturierter daher kommt. Außerdem sind noch mehr Details in der Musik wahrnehmbar, die vorher wohl irgendwie im alten Kabel verloren gegangen sind. Das fuhr zu etwas mehr Luft zwischen den Musikern und noch etwas besserem Raumeindruck.

In Summe also mehr Präzision bei gleichzeitig natürlicherem Klang, zwei Eigenschaften die sich normalerweise gegeseitig ausschließen...

I replaced my WireWorld Mini-Eclipse 7 loudspeaker cable with a C-MARC Coaxial wired as a single polarity. I'm most impressed by the way that - through a change of loudspeaker cable(!) - sibilants are now less harsh. For example, when I listen to Livingston Taylor's whistling in his song "Isn't she lovely" with the older cables, it came through as a cutting, almost painful tone which hurt my ears. With the LessLoss cables, this uncomfortable aspect disappeared completely and the whistling now sounds wonderfully natural. In addition, now the bass is considerably deeper, despite using tube amps, and has better impact and is structured and more solid. Also, I can hear more detail in the music which were somehow completely missing in the older cable. This leads to more "air" between the musicians and a better sense of soundstage.

To sum it up, I'm getting more precision and at the same time a more natural sound, two traits that you'd normally consider contradictory...

Firewall Module; C-MARC bulk wire and cable

Date Added: 02/20/2020 
[High performance joint partnership recording between LessLoss, Boenicke Audio and Audio Consulting, implemented using C-MARC Hook-up wire and LessLoss latest Firewall technology.]

I've had a chance to listen to the recording by now, and it is really incredible - thank you!

Since I downloaded it late at night, I first listened through headphones. There, I was first struck by clarity and dynamics. But the real thing, I believe, only comes through the speakers. It is there that I really appreciated not only the quality but also the technique of the recording. It is one of the very few piano recordings I’ve heard where you almost get the tactile experience alongside the sonic one. It places you not in the audience but almost on the performer’s stool, as it were. (BTW, I have to listen more to it, but my first impression was that the positions of some mikes were changed for the second CD, no?) The middle parts of Part 4 and Part 5 are truly amazing: the way lower and higher octaves sound together, losing neither their distinctiveness nor togetherness, is, again, something I don’t think I heard before in piano recordings.

So thank you again!

C-MARC bulk wire and cable

Date Added: 03/01/2020 by Vladimir Markovic
Since I replaced my Cardas speaker cable by C-MARC wire, I am still in a state of shock.
It is simply a magical improvement.

I still did not get around to rewiring my amp and turntable with the remainder of the C-MARC bulk wire. I just HAD to continue listening to music ever since the C-MARC has been in my speaker system.

C-MARC bulk wire and cable; Firewall Module

Date Added: 09/16/2020 by Colin Gray
The boxes at my ‘speaker terminals (pic attached) house Bybee Speaker Bullets and they remained in my system and because of the configuration, the Firewalls plug into them.

Whilst I save up for the C-MARC Entropic Process power cords, I was planning to rehouse the Bybee products (currently in the plastic box) in an enclosure similar to the mains Firewalls with the material being Russian Birch ply as per my ‘speakers.

However, for the tails leading out to the Cardas terminals on my ‘speakers, I wound up using the ‘Large’ C-Marc bulk wire, Entropic Process (this option provided by LessLoss).

I continue to marvel every single evening as I listen to the transformation of my system with the various Lessloss products. My favourite music has never sounded so good and it keeps getting better as I said at the start of the email.

Here are before and after images.

I’ve had just over a week with my latest project with the new enclosures for the Bybee Purifiers. I know that my Entropic Processed power cords only really showed their brilliance after 7 days, but of course my new C-MARC ‘tails’ are not seeing mains power. I expect them to take a bit longer to show their full merit. However, I knew from the first minute that they had brought an obvious improvement. OK, there is the new Birch-ply enclosures and the Bybee Purifiers embedded in Epoxy, but I feel the majority of the improvement comes from the C-MARC. The improvement being more of the same from your products, i.e. better clarity and realism.

I thought, pre my Lessloss journey, that my system sounded really good. How wrong was I and how much ‘noise’ was there that I knew nothing about! My best way of describing it is that for ‘noise’ read glue. Previously the sound seemed stuck to the ‘speakers and the vocals / instruments stuck to each other. With each iteration of adding a Lessloss product, the glue has been progressively removed and the sound just fills the room and is totally detached from the ‘speakers. Each vocal (lead and backing) and every instrument is now free in its own space.

With this latest DIY project, just 200mm of Entropic Processed C-MARC has taken away some more of the glue. Remarkable for such a low-cost project.

Downsides – well yes - Entropic Processed C-MARC is ADDICTIVE – I need more!!!

Thanks again.

C-MARC RCA unbalanced signal cable, stereo pair; C-MARC bulk wire and cable

Date Added: 12/11/2020 by Barnabás Komáromi from Hungary
Yesterday I purchased my first LessLoss cable. I wanted to put an analogue interconnect between my player and my amp. My stereo system is not really high end category because in the past years I invested more into headphone gear.

I could not use the standard C-MARC RCA that you make (with those Large Xhadow silver plugs), because my "cheap" devices have the RCA sockets too near for each other.

So my technician colleague assembled a cable for me, using C-MARC bulk coax and these "low weight, nickel-free, gold plated tellurium copper" connectors.

Why C-MARC for such entry level gear? Because I wanted to buy one reference cable, that stays in my system even if I upgrade electronics. Also, I wanted something flexible. I hate thick PVC.

From the first minute, my system showed a completely new image. Transparency improved and at the same time I started to hear the limitations of my player and the CD discs as well.

What I like about this cable is that it's not trying to make everything beautiful like a fairy tale. It makes my system more honest, more straight. At the same time it shows the pure details, the small details in space and time.

So I'm happy because now I can listen to my stereo with my wife and I don't have to go always to my headphones.

I tested a lot of your products in other systems for the past years and I knew that they are working, but it is always so intense, such a milestone to experience good changes in your own device chain.

Thanks again and I will be happy to continue recommending your products.

C-MARC bulk wire and cable

Date Added: 12/20/2020 by Pascal, from Guadeloupe
Are you ready for the C-Marc bulk cable "Large" verdict in my high efficiency speakers (96.5 db!)?

Well I'm not going to use all the audiophile terms but the only thing I can say is that these cables bring finesse and allow the details to have more materialization, they are a little more embodied, of authenticity!

While waiting to familiarize myself a little more, I am saving up to test the DIY Firewalls for loudspeakers! So The sequel in a future episode!

Thank you for allowing me to improve noticeably but surely listening to my system!

C-MARC bulk wire and cable

Date Added: 05/31/2021 
Making a magnificent DIY C-MARC headphone cable

After I upgraded all my interconnects to C-MARC and also exchanged most of the internal hook-up wire/signal cable in my Rogue Audio tube amps with success, I surely got magnificent and improved results.

I was looking for a new upgrade project for my head-fi, because quite often I use my Audeze LCD together with my Audiovalve tube amp. Sometimes I must be gentle and select quieter listing environment and I do want to listen without losing the same organic live sound as I do with my loudspeakers, without any lack of detail.

With headphones you get closer to the music. And the cable that comes with the headphones is rather good/ok but my idea was it could be yet further improved using C-MARC wiring. Since the LCD-3 has XLR mini plugs I could make a replica cable without opening the LCD-3, and make it longer. So I did. I used 8 meters (4x2m) of C-MARC Small hook-up wire purchased with unprepared ends and unterminated. Since I have been working with C-MARC wires/cables upgrades, I have learned the technique to prepared the ends by use of soldering pot and high temperature to burn off the lacquer and tinning them. If you's rather just want them already treated and finished in 4m lengths that's easy to order. One thing you don't have to worry about is using shielded wires over the pair. They are self-shielding by their very construction.

• Ok, after termination and soldering to a jack plug and the mini plugs I was very curious if there were going to be subtle changes or in some ways better. Immediately without burn-in time there were huge changes in sound. More organic, an ease of music flow, it was wider and deeper. All the instruments were better and real and I heard no coloration. Just closer to the music, and that's what we want, right?

• Again I am surprised what C-MARC can do and the changes they bring about. You can use them in power, signal paths, digital, low signal wires from PU to RIAA. I just love them!

Power Distributor; Firewall Module; C-MARC bulk wire and cable

Date Added: 10/18/2022 by Philippe Montavon
My audio system is a highly sensitive and very transparent one, using very high sensitivity field coil full range speakers and also field coil bass speakers. The tube amplifier that drives the full range speakers (Rullits) offers only about 3 Watts. So, my description of the effects of the 640x Firewalls pertains to a high sensitivity (including high hum sensitivity) tube driven system.

It has been optimised over the years with much dedication, including the use of Firewalls for loudspeakers and Firewalls for power supply. So, I was not expecting such a range of improvements upon implementing this home-made power distributor using one DIY 640x Firewall per power cable (8 Firewalls for 8 power cables). I might even consider building a second distributor to take care of the remaining power cords!

I believe that the use of one Firewall per power cord minimises detrimental electrical interactions between the various pieces of equipment, which clearly translates into less hum and a clearer musical signal.

I finalised my 8 channel power distributor using 8 of your DIY 640x Firewalls, one per channel/output. I use one power transformer (connecting 400V from the 3 phase electrical supply of my flat to its primary, which translates to 230V on its secondary) to feed my entire audio system and achieve galvanic separation.

Grounds proceed via separate connectors, one on each piece of equipment of my system (implemented by me), which, through C-MARC wires, converge onto a single soldering point and then travel through two 640x Firewalls before being connected to earth.

Accordingly, since the grounding network of the system is fully separate from Line and Neutral, I did use Ground and Neutral of the 640x Firewalls in parallel to account for Neutral. Line was used as usual.

I powered all digital related equipment, part of the tube gear, and part of the field coil power supplies with this power distributor. There are still about 8 pieces of equipment which are not powered by this DIY 640x power distributor. Some of the pieces of my system already housed a DIY 640x, internally connected to the primary of the respective power transformers.

Listening to the system after implementation was a great pleasure. The already low hum level of this complex system went even lower, nearly undetectable! Depth and width of the musical stages increased. Unknown low level information appeared, which also translated into increased harmonic richness of instruments and voices and an increased dynamic range.

Acoustics of the recording space became more obvious, which revealed the three dimensional structure of the musical scenery. That means a lot when considering the pleasure it conveys when listening to music!!!

So, great stuff indeed.

C-MARC bulk wire and cable

Date Added: 03/28/2023 by Nik
Hello Louis,

I own the „big“ CD-transport from Pro-Ject, the “CD Box RS2 T”.

It is driven by the Pro-Ject upgrade power-supply.
The DC-connection was via Pro-Ject “upgrade” cable.

Last weekend I built a new DC-cable for this connection, using C-MARC™ bulk Coaxial cable.

What shall I say – big improvement!

So why don’t you offer DC-cables to non DIYers?

Regards,
Nik
