Firewall Module

Date Added: 11/24/2019 by Joerg Meinhardt
The Firewall for Loudspeakers after more than 250 active hours.

Please also see my first review from Oct 28, 2019.

Still totally happy with these firewalls on my loudspeakers. Anything I could have hoped for and lots more improvements!!

Actually the ongoing progress of the burn-in is not as bothering as I know from other recent changes, no matter of what kind they were. The 3D was sometimes flatter, the dynamics a little smaller, but no harshness at all. So it was always better than before the implementation and never really frustrating!!!

After a couple of weeks, the room turned impressively more airy and larger again. Transients are driving the scenery more than ever before. Less resonances also. It reminds me strongly of my previous electrostatic speakers in those aspects, just without the downsides :) And since then, it still got more of all.

Thanks, Louis and team, again and again and again :)

And for all others:
GO GET THE EARLY BIRD DEAL !!!

I have received the loudspeaker firewall and it has now played some 48 hours. There is a substantial improvement in timbre and fidelity. The sound has excellent transients, 3D perspective and conveys the ambiance of the recording venue very well.

The loudspeaker firewall is unique in the hifi world and a must have for all enthusiasts.

Congratuations for another excellent product.

Loudspeaker Firewall first impressions

After a long, but totally understandable waiting time, I received my double pack of the new loudspeaker firewalls for my bi-wiring speakers yesterday and am so happy now!

Even though, we all know, that parts like these, should have some burn-in time before making a final judgement; I would like to share my early impressions after only 20 hrs, because it is just so great.

The looks are very special with organic and technical looking parts combined. They feel and look like a valuable well made piece and to me seem smaller, that the close up pictures, we were able to see earlier.

Plugging in with a good tight grip of the connectors was so easy, because they are carrying the typical red/black markers.

The very first minutes already showed, that I was listening to a great improvement and this has gotten better with each hour so far. No initial harshness, but space and details were opening up more with time. So these are my findings so far:

-- Strongly improved control of sibilance. No sharp or almost metallic artefacts, that I before was hearing sometimes. It now feels like a believable and natural amount of sibilance.
-- Transients have a great match to the timbre of the source, which makes deciphering complex arrangements easier, especially with percussion.
-- All sources are richer in sound and display their building materials. Standup bass and piano now reveal their wooden bodies a lot more besides their strings. The timbres are more specific.
-- Voices are just gorgeous, now popping out a lot more, very clean but still increased richness.
-- Positioning of sources on the stage is more obvious. All seems to have more space and the speakers are not in the focus of the listening experience,
-- And finally the bass … again deeper and better controlled and more oomph and authority.

You might find my other reviews about my previous LessLoss items, the custom power distributor with firewall, the C-Marc power cable, or the bang for the buck Bindbreaker. This loudspeaker firewall is a definite no brainer to buy given the price … especially if you are not bothered with a bi-wire loudspeaker like me. It so much refines the previous purchases. Hard to imagine, but it still got better … definitely did and probably will even more with the burn-in.

Thanks so much Louis and LessLoss team for another wonderful product.


Next day:

The space just exploded and I was beamed into another universe.
Had it running at low level all night and morning until I came back from dog walk and shopping … And finally started listening not being in any way prepared … Just found all sound away from the loudspeakers way into the room and through the front wall. And everything so smooth still more dynamic and even more oomph bass … and finally a really big grin in my face :):):):)

Thank you sooooo much, Louis!

C-MARC bulk wire and cable; Firewall Module

Date Added: 10/22/2019 by Apirameth U.
Power distributor with integrated Firewall modules using C-MARC wire throughout.

The power distributor arrived a month ago. After full Burn-in for 3 weeks, yesterday I started to connect it to my main audio system, first impression is the noise floor level is much lower, the notes of each music instrument are very well seperated, the sound of intruments are more real.

The dynamics are simply excellent. I feel that the musicians, now, are playing with their soul. Most important thing is it makes me connect to many albums of music like never before. A very great and world class product.

Thank you to you and the LessLoss team for the professionalism and keep going with continuing to develop great products like this.

I am about 16 hours into listening to the New Speaker Firewalls. And my first reaction is "WOW"! The sound is more detailed than before and it is remarkably balanced across the audio spectrum. I am hearing the subtle and slight sub harmonic sounds that a singer will make in a performance. Something that you might observe in real life but certainly not consistently on a recording. There is just more of a sense of realism. It is quite intoxicating! Even Recordings that I didn't particularly care for before, I am rediscovering. To top it off I was impressed with the bass output of one of my recordings when I realized my sub-woofers had been accidently disconnected. I am speechless. Can't wait to see if these magical devices break in further!

First audition of the new Firewall for Loudspeakers.

Just today for an hour or so. Already I hear more detail and feel more drawn into the music! Isn’t that what its all about?! Hard to turn off my CD player. Funny: after less than 10 minutes the new FWs sounded less harsh and warmer! I wonder if you have any idea about total recommended break-in period for these little guys?

First 10 minutes: already a quick change! Smoother and warmer and cleaner. A nice ugrade. I thought “this is nice. If that’s all, well, O.K”. Then after about 50 hours: Wow!. When I thought we were done, another LOVELY upgrade!! Richer, more zeroed in on the instruments, whatever they were, more music popping out at you! A “it sounds so present experience". Cleaner yet. And just makes me listen sometimes well past my bedtime…. I wonder if others have had the same break-in experience with these? Unlike most of my other break-in experiences (mostly with your products, since those are what I’ve been buying lately!).

Firewall Module

Today I received the loudspeaker Firewalls. They look fascinating and totally unique.

I haven’t got the time today for extensive listening, so I took four discs with different material, listened to four tracks without the Speaker Firewalls installed and thought to myself, wow it sounds so good.

From the start I didn’t know what to expect with this totally unusual passive device. And it comes with two more connections, where every HiFi-Pope tells you that it is poison to the sound quality.

I installed the Firewalls and listened to the same tracks again. Maybe not optimal to post a comment right after unboxing without burn in. But do the Firewalls need any?

What did I get with first listening?

More of everything! More details, bass, ambience, clarity, better separation of instruments, wider frequency response, dynamic improvement, musicality, and did I mention details?

The discs sounded completely different! I never thought that a passive device like this can come with such a gigantic improvement.

I sat there stunned and couldn’t believe what I heard.

The speaker Firewall makes the biggest improvement of sound quality ever. This is simply a fantastic device and I would run out of superlatives to describe it. It’s marvelous! A revolution at a bargain price.

Thank you for creating this wonderful product that outshines anything comparable.

Wow, you have surpassed any thinkable expectation. Great!

Firewall Module; C-MARC bulk wire and cable

Date Added: 08/26/2019 by Joseph LG
I finally finished the power conditioner/distributor. I could have finished it a long time ago, but other projects took priority. With the FW module and cables you provided, it was not difficult to assemble. Pics of the completed project are attached. I also attached a photo of the LessLoss-provided parts.

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.

C-MARC Classic Power Cable; Firewall Module; C-MARC RCA unbalanced signal cable, stereo pair; C-MARC XLR balanced signal cable, stereo pair; C-MARC loudspeaker cable, stereo pair; C-MARC Digital Cable

Date Added: 08/20/2019 by H, New York
The Less Loss C-MARC range is the most appealing and effective cabling and power treatment I have ever found at its price point and at those 2x or 3x above. To get to the punchline, a complete set — interconnects, speaker cables, digital coax, power cords, and C-MARC Firewall 64x for each component — delivered in my system created (1) more focus and coherence around vocals and instrumentation along with a larger soundstage (2) less harshness around some highs; and (3) rich but controlled and tighter bass. The biggest improvement, however, is in the overall musicality and listening engagement which is MUCH higher with the C-MARC cable set for every genre of music I tried. The cabling allows the listener to shift focus from the cerebral aspects of critical listening in which each part of the musical performance is considered in a piecemeal manner to simply enjoying the music. For any one who values their system and is open to improvement, an audition of the full C-MARC kit is highly recommended and I would say should be nearly a requirement for anyone starting a system from scratch.

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.
