Firewall Module

Date Added: 01/06/2025 by Edward Swiderski
These remarks concern the Lessloss Stellar Firewalls for loudspeakers.

My system is highly resolving, consisting of the following components (partial listing):

- Loudspeakers: PMC Twenty5 26i
- Amplifiers: Luxman 509Z Integrated; Pass XA 25 power amplifier paired with Icon Pro 4 SE balanced passive preamplifier
- DACs: Lamipizator Baltic 4; Holo May ‘KTE’
- CD transport: Jay’s Audio CDT MKIII
- Streamer : Matrix Element S
- Speaker cables : Audience AU24 SX ; JPS Superconductor V
- Interconnects : Audience AU24 XLR & RCA ; JPS Superconductor V
- Digital : Curious cable (blue) USB ; Tubulus I2S & Aes/Ebu
- Power cables: Lessloss; Isotek; Xindak
- Power conditioner: Audioquest Niagra 1200.
- Decoupling devices: Auva 100s and 50s; Symposium Padz and Roller Blocks

Upon inserting the Stellars into the system I was presented with a vividly clear, bright sound quite unlike the original Lessloss firewalls for speakers that I had been using for a few years. Initially, the sound was somewhat harsh accentuating the high frequences somewhat to the detriment of the mids and lows. However, I was correct to assume that some burn-in was needed: after approximately 20 hrs the Stellars appeared to settle, and I began enjoying a clear, transparent, slightly forward sound across the frequency spectrum. As I prefer a more relaxed sound, less forward, I experimented with speaker positioning: I discovered that by moving the speakers forward, not back, and increasing their separation, I achieved a more neutral, balanced and extended soundscape, any residual brightness or glare being ascribable to the materials/recordings. The noise floor is considerably lowered, graininess is virtually absent (depending on the source material), resolution is greater, listening levels can be moderate with no loss of musical fidelity.

In short: Not only are the Stellar firewalls a considerable improvement over the regular speaker speaker firewalls, they are a major addition to the audio excellence of my system.

Firewall Module; C-MARC Stellar Power Cable

Date Added: 11/27/2024 by Jean-Michel Anquetil
"Stellar" is the right name!

I received a few days ago another Stellar power cord (replacing a C-MARC Entropic) and another C-MARC Firewall 640x filter.

I already have another Stellar power cord for my amplifier.

These products are now powering my DAC stack (Totaldac D1 direct, Reclocker and D1 drive). The result is again mind, I should write, "musical blowing". This cable brings more silence, more flow to the music, reveals very detailed shade and nuances ... all that makes the music so very lifelike and enjoyable ... The result is so much musical pleasure.

I have many LessLoss products and they all work in harmony to provide more natural music. There is so much hidden music in our files and records which are now revealed.

Well done Louis, thanks.

Firewall Module

Date Added: 11/10/2024 by Maurizio
In the past, I had equipped my stereo system with the BlackGround 10x Power Base and experienced a remarkable leap ahead in quality of the reproduced music,
particularly in terms of transparency and clarity. Then, following the advice of Louis Motek, I inserted Stellar Firewall Modules on my loudspeakers.

Although I have always been, by instinct, reluctant to insert any additional device on a signal line, I can state that, after a run-in period of about 180 hours, the Stellar modules did not penalize any aspect of the reproduction of music of my stereo.

But it was after about 300 hours of playing music that the remarkable benefits of the Stellar firewall modules showed in full.

The modules bring noticeable improvements on clarity of highs, especially for the most challenging recorded tracks of complex music.

I can now listen to lower pitched notes that are well articulated and neatly reproduced.

The musical scene enjoyed an increase in both accuracy and stability in space.

The quality of tonality, so much advertised by the manufacturer of my DAC, is now as simple as impressively right.

The purity of some feminine voices that were sometimes not reproduced at the same usual high level by my stereo, are now stable in time and rendered with much more subtleties than in the past.

Again a wonderful upgrade, this time the Firewall for Loudspeakers Stellar version.

Since 2019, I have the first version of the Firewalls for Loudspeakers with some upgrades to daisy chain on other loudspeakers with separated crossovers. Feel free to check the reviews from that time. I was very excited and up to just 3 weeks ago very happy with them.

Since 3 weeks now, I have the Stellar version in my system and am very happy and astonished of this improvement. Just switched back to to the “old” one, to check whether I was not remembering falsely. And yes, it was correct:

Just as always, everything is better, more natural and realistic, like:
- Stage wider in all directions
- Instruments and voices are better separated
- Background more silent then ever
- Attacks improved
- Bass have more structure
- Loudspeakers disappear … probably best what can be
- Better decryption of lyrics
…

Today, the “old” non Stellar are going back to LessLoss. Such a great way to upgrade with a good price and no worries about selling the old ones.

Thanks again, Louis and team, and gratulations for this new product. I love it!!

Stellar Firewalls for Loudspeakers are otherworldly!

I won’t apologize for sounding like a LessLoss fanboy! The Power Base, Speaker Base, Stellar Power Cables, 640x Entropic Power Modules, Standard Firewalls for Loudspeakers and Entropic Speaker Cable & jumpers I have in my setup combine synergistically to produce the most heavenly sound!

However, a recent upgrade from Standard Firewalls to the brand new Stellar edition have transformed my system from dreamy to otherworldly! Speakers vanish into blackness. Poof! Walls disappear. Poof! Music floats free & easy. Soundstage wide, tall & deep. More space around musicians & instruments. Their locations well defined. I’m able to see & hear behind each note played. Very holographic!

It’s as if I traded my very nice seats as an observer to become an active participant on stage in the making of music. The emotional attachment is intoxicating!

The LessLoss trade up program is both generous & easy. 2 stereo pairs of Standard Firewalls, 4 individual Firewalls per speaker, became Stellars configured in series, 2 red & 2 black per speaker. After 100hrs of run in time, this upgrade, combined with the other excellent LessLoss products in my system, represents a dramatic leap forward. I’ve never felt closer to the music than I do now!

Bravo Louis & LessLoss!

C-MARC Stellar Power Cable; Firewall Module; Power Distributor; BlackGround 6x/10x Power Base; BlackGround 8x/10x Speaker Base

Date Added: 01/09/2024 by KH
I have been a supporter and believer of LessLoss product since 2023.

I am currently using BlackGround 10x Power Base, BlackGround 8x Speaker Base, Firewall 640x and also 5 Stellar power cords….

I took the opportunity of the upgrade program to upgrade 5 pcs of Entropic Classic power cords to Stellar.

My setup is streaming based and I was using the Entropic Classic to connect to LessLoss power distributor, streamer, usb regenerator, network switch and 10x Power Base.

When I initially switched from my old power cords to Entropic Classic, the experience was a revelation..the feeling of “live” performance..the background is so quiet yet lively at the same time..the other improvement were increase in depth and width of music..and big reduction in digititis…please note that I am only streaming music through tidal and I am already getting this much of satisfaction.

Now, upgrading from Entropic Classic to Stellar power cord, what I experienced is a definite improvement over Entropic Classic..the improvement I experience in Entropic Classic applies here and are further amplified.. I also experienced increase in dynamics and increase in bass quality and bass output..the increase in bass feels like I have upgraded my amplifier or speaker. What really impress me is on vocal..vocal is much much improved over Entropic Classic..to the point there is really no listening fatigue. The glare that I normally experience in digital setup is gone. Previously there are certain artist which I find it hard to listen to, such as Celine Dion Immortality..i had to lower the volume when the songs reaches chorus/climaxes as its too piercing to my ear.. but with Stellar, I no longer need to lower the volume..in fact, I can increase the volume now and hear even more details than before.

All in all, the upgrade to Stellar was a worthwhile one and I greatly recommend this product.

Echo's End; Firewall Module; Bindbreaker; C-MARC Classic Power Cable; Power Distributor

Date Added: 08/28/2023 by Julian
I thought I would give you feedback on the products I have and the sound of my system.

Products purchased so far.

C-MARC Classic power cord 2 metre Entropic
5 of Firewall 640x (2 of which are C-MARC)
2 sets of Bindbreaker Equipment feet
Power Distributor

and the star of the show Echo’s End Reference DAC.

These products have all contributed to making the sound of my system enjoyable to listen to. I now want to listen to my hifi system again, and looking to play CDs which I have not played for a long time (This is testament to how well things are).

When I had the Echos' End Reference on loan it was touch and go whether I kept it. Basically (to my ears) there was too much attack / power to leading edge of strings (guitar) when they came in on the tracks I was using for the evaluation. In one sense a small thing, but when investing that much money I felt things had to be right. I then had an idea, a set of supports I had put in I never gauged the difference they made or not. This pretty much corrected the issue, and along with talking to Elite Audio (UK) I felt mentally more positive (state of mind does have an effect too). After further listening I was then completely happy with the sound.

The change involved removing the supports I had put under, not the CD transport, but the external linear power supply. Hifi to me is not always a science, but behaves more like an art form.

I was really concerned about bass from the Reference seeing other peoples review, but this has not been an issue. What it is is open and balanced (i.e. covers top end and bottom end equally). On a recent listening it is almost like you can hear the other side of the notes. Beautiful sounds which waft over, and work with my ears (a big thing for me).

Will be looking to add more. Following your advice, more power cables and Bindbreakers. Eventually looking to BackGround 10x Power Base, and your last Newsletter reminded me of a couple of the Blackbodies conditioners.

Many thanks for your company's products and design philosophy.

Firewall Module

Date Added: 04/25/2023 by Thomas Yu
As might be first user from Taiwan:
I used 640x C-MARC™.
Connected to the computer: the sound contrast is increased, smooth and black, and at the same time, it seems to be 1-2db more.
Connected to DAC: The mouth shape of the human voice is relatively round, and the fluctuation is obvious. Remove the firewall, similar to cooking curry without chocolate or butterl.
Connected to the tube amplifier: the extremely low frequency is much clearer, the sound field can be lowered instead of running to the sides.
Connected to class D amplifier purifi: the treble becomes less bland, became more engaging.
Connecting to the Powerline/Power Distributors: the appeal is close to connecting to the DAC, the overall sound field is improved and the depth is stretched before and after, and the separation between instruments is good.
Listening to Imagine dragon believers, the distribution is clear, and the vocals and guitars are divided open.
Although The low-frequency sound field is not as good and deep as Connected to the tube amplifier, but it still with very good body of base.

Really thumb Up for better musical density and body.

Firewall Module; C-MARC Classic Power Cable; Power Distributor

Date Added: 04/05/2023 by John
Improvements in audio are a curious thing; one cannot imagine what something might sound like once improved since one's ears are tuned to whatever exists. One is happy - even ecstatic - with how things sound at the time. This is how I was, feeling that the level of clarity, definition and detail was far greater than I had ever experienced. Yet, like all psychopath audiophiles (!!!) I am always striving to find more more more!!! Or, as is the case here, less less less of things I didn't know I was hearing.

During my last date with my installer we incorporated your power conditioners as you suggested, using your power cables. We eliminated the Nordost units except for a few pieces that are not in the audio chain, and on an entirely different circuit.

And I was immediately struck by an even "blacker" background, the sound emanating from what I can only call a "pool of purity" - with no influence from external noise, interference or sound coloration. I had never heard music sound so independent of degradation.

As you mention on your website, there was a noticeable break-in period, but it wasn't too drastic; there were days things sounded different than other days, but never horrible (like during my speaker break-in period! That was horrible!). Things have settled now and I wanted you to know how incredibly happy I am with your stuff. Very impressive - my installer also was blown away... I'm sure you've found a new fan, advocate and buyer in him.

Thanks again for what you do - take care,
John

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.
