Since a while I have the Lessloss Firewall for loudspeakers. It is an unbelievable improvement in terms of natural treble and tone colours. Without it seems to sound pale.

Good job Louis!

[Plug-and-Play C-MARC Firewall 64X]

One thing is certain: your products make my system progress in the direction I want: homogeneity, stability, depth, atmosphere, harmonics, control of the extremes of the spectrum, reduction of distortions and "stresses" on treble and "Forte." They allow me to push it to its limits, but above all to approach a soothing listening experience and fullness…

The Firewall for Loudspeakers is an amazing product. The improvement to my system was immediate and significant. Bass is tighter, higher frequencies are clearer, there is more separation between instruments, music is richer and fuller. It's honestly quite a shock to hear the change.

Considering the money I have spent on cable upgrades and other tweaks the Firewall for Loudspeakers is a bargain, the improvements are quite astounding particularly as I thought my system was already at quite a good level.

This is the first LessLoss product I have, looking forward to adding more products to my system.

C-MARC Classic Power Cable; Firewall Module

Date Added: 05/04/2020 by Michael Hollesen, Klutz Design
[Complete loom of C-MARC Entropic Process power cables and LessLoss power distributor with onboard Firewall tech.]

Everything installed Thursday - but from having played at many shows I truly believe that “gear doesn’t travel well and the molecules need to settle” - which is why day two at shows always sound better. And so it was here as well. Though things were unmistakably amazing yesterday - today is beyond.

Really difficult to put into a few words - but I’ll try:

I don’t have a hifi stereo system any more.

I feel the strings. The air between. And previously compressed complex classical pieces opened up. Cymbals and high hats are just there with their metallic decay, voices so close you expect to be able to reach out to touch the singers, sound staging that makes the already invisible open battle speakers obliterate the room (if the recording allows it), a calmness in the presentation which creates quite an unnerving realness and uncovers finest details. The creaking of a chair, the breathing of a cellist or just the multiple layers hidden within the music.

You hinted at a remarkable performance - truthfully I don’t think you could prepare anyone for such a significant experience. The combination of the firewall distributor (with C-Marc Entropic cabling) together with the Entropic Process power cables is absolutely incredible. Congratulations - to myself for getting this ;-) and for your fantastic work.

[Firewall for Loudspeakers]

Wow, I'm really impressed, and (even more incredibly) nearly speechless at the transformation produced by installing the FW for Loudspeakers. The magnitude of the change was dramatic even after a couple of hours of continuous playing, but it has just gotten better and better as the days rolled on. All the usual cliches about darker background, more detail etc, spring to mind, but the bottom line is that, in terms of clarity, smoothness, dynamic range, subtle detail, my audio system doesn't sound anything like it did before. As days of continuous usage passed, I tested the FWs by playing hi-res tracks all of which had passages that had previously been abrasive in varying degrees, and one by one those recordings just sounded more open and alive and dynamic, without a touch of discomfort. And I found myself hearing subtle ambient information about the recording venue that I'd not heard before. Overall, imaging has become astonishingly more lifelike.

I've now dared to flout advice about social distancing and have demonstrated the FWs to several friends, all of whom were floored by the evolution of my system (and who were quite familiar with the sound of the system pre-FW). One of my friends has 2nd-gen Bybee bullets, and he conceded that they never wrought such a dramatic and beneficial change in his setup. As soon as our local audio club resumes meetings, I look forward to hosting one, if only to see more jaws drop.

I should add that this change was on top of a complete cable upgrade to C-MARC power cords and interconnects (from other previous LessLoss cables). They, too, greatly elevated the sound of my audio system. But these had been broken-in quite a lot already by the time I installed the FW for Loudspeakers. So it was clear how much more dramatic and sweeping that transformation was compared to the cable upgrade. I'm thinking there should be a Nobel prize for audio...

I recently auditioned the LessLoss 'Firewall for Speakers' module... used with my Tidal Contriva Dicera-SE speakers. My system, consisting of the Tidal speakers... Chalice Audio 'Grail' mono block SET amplifiers, Lumin S1 network player, and REL 212 -SE subs x 2, as well as my cables... Prior to inserting the Firewalls into the system I read, with great interest, the 6Moons review. I have used a number of Mr. Motek's [LessLoss] products in my system over the last few years, each with mild to moderate success. All in the cable realm. I contacted Constantin, at Atelier 13 Audio in USA, after asking Mr. Motek about dealers in the USA. He is a very professional gentleman with a great website and represents many great audio products. He sent me a pair for each speaker along with a sample of the LessLoss C-MARC RCA interconnects. 'Spoiler Alert'....right out of the box I was just amazed at the improvement to every aspect of my system's presentation. I had one of my audio friends over the next day, who knows my system very well, and he could not believe the improvement. If you want to find out what you have been missing on your CDs, streamed albums, or downloaded discs, this will allow you to hear it. The demo pairs were new and had not been used prior to my trying them. My system is, to my ears, the best system I have heard, and I did not think it could be even improved a little, let alone what I heard. I had tried many potential tweaks in my system without any significant improvements. The soundstage width, depth, the detail, the tonality, the vocal realism and the 'you are there' feeling is just amazing. I might add that when I substituted the C-MARC interconnect in, things improved even more. That replaced a cable 4 times its price. Both products are staying with me. I will be trying the C-MARC speaker cables next and then their new Entropic Process power cables.

I have the Firewall for Loudspeakers in my system for a few days now.

System consists of Innuos Zenith Mk3 ---- SoTM TX usb Utra ---- PS Audio Directstream Dac ---- Audio Flight FLS10 Int. amp. ---- Audiovector Avantgarde Speakers.

After a slight improvement in SQ in the initial few hours the Firewall for Loudspeakers have been a revelation after three days in the system.
The bass is way more solid and tight and treble is distinct without being in any sense bright.
Each instrument is now completely separate whereas before, there was a certain blending which I did not notice until it was gone.
I feel like a veil has been lifted from the speakers and they now are playing to their full potential.
I am so happy I purchased these unique little units.

Firewall Module

Date Added: 03/31/2020 by The Good Doctor... and his patient wife...
Louis:
Thank you for your support and product. Nicely made, fairly priced and worth the wait. Paraphrasing and plagiarizing those with better ears I will use the terms, "more musical, less mechanical" and bringing a supple fluidity to brass and voice. Tone is more 'elastic' and 'sensual'. This took less time for my wife to appreciate, as is usually the case, but after 16-20 hrs my appreciation of your efforts aligned with those who have previously sent reviews. Not to the same degree but perhaps with more time and more wine... well done.

I’ve been running in the speaker Firewalls for about 3 weeks.

At this point, I'm very happy with the Firewalls — they were worth the cost. The difference they have made is an extension of the difference your other products have made — an even bigger, almost holographic soundstage (especially reaching out toward the listening chair), more air between instruments and more density to individual notes, less glare, an almost liquid presentation to whatever music I am playing.

It helped to adjust my speaker placement after breaking in the firewalls. Strikes me that it makes sense to do that any time you add something to your system.

Associated Equipment:

Lumin S1 server with L1 hard drive
Coincident Technology Frankenstein MK. II monobocks with Takatsuki 300B valves
Ref. 3A Taksim loudspeakers
Torus RM-15+ power conditioner
Wattgate wall receptacles
LessLoss C-Marc speaker cables and interconnects
WireWorld Cat. 8 Platinum digital cables
for isolation, a combination of Rollerblocks, LessLoss Bindbreakers, and Isoacoustics (for speakers).
All cables, fuses, and receptacles treated with Perfect Path graphene paste.

C-MARC loudspeaker cable, stereo pair; Firewall Module; C-MARC RCA unbalanced signal cable, stereo pair

Date Added: 03/22/2020 
First of all, I would like to thank you for the excellent cable and speaker firewalls and for the excellent customer service.

Now the RCA and triaxial speaker cables are also playing in my music system.
Although the cables haven't yet played music for long, I am already enthusiastic about the musicality.
For me, the cables and speaker firewalls are an absolute must in my music system.
Without this, I miss the tonal substance, the timing, the fine details and the musical energy that are so important for my perception of authentic music.
The music now sounds even more powerful, dynamic and homogeneous.

With these unique cables and FireWalls I have the feeling that I can fully exploit the potential of my music system (LDMS server including Ideon Audio 3R Master Time, Lampizator SE GG 2.5 Pacific Edition including preamplifier, NAT transmitter, Harbeth 40.2, etc.).
In addition, the cables and firewalls are very meticulously and precisely manufactured.
My eyes are spoiled too.

I am very happy that I chose LessLoss!
Stay healthy.

Thank you very much and good luck.
