Firewall Module

Date Added: 01/14/2020 by Colin Gray
The Firewalls for Loudspeakers are another HUGE success in my system!

This is a perfect example of how one thinks all the ‘noise’ has already been removed from the system, after the great success of the Firewalls for mains power, but with these new modules now added, yet further dramatic improvements have been achieved.

These improvements are along the same lines as with the power Firewalls, i.e. simply put, yet more clarity and realism.

The clear message is that, no matter how good you think that your system sounds, you simply don’t know what ‘noise’ is still there, degrading the SQ of the music, until it has been removed.

Thanks again for yet another remarkable product.

I would like to tell all of your potential future owners and/or current owners of any and all LessLoss products, past or current, that because I have a coterie of close friends and former associates who are always anxious to buy (for the past several years, only LessLoss offerings) from one owner (me) of LessLoss products, I have been in the process of upgrading. Because of that fortunate position I have been an owner of virtually every power cable, USB cable, USB keys, interconnect, Firewall 1x through 64x, analog hardware from the Echo's End Original to the Reference and now to the Reference Supreme twin-chassis unit.

These statements are not driven by an ego trip or braggadocio. It is jut a statement of fact based upon my personal experience as an audio hobbyist which began decades ago by building much of my original equipment. Over those many years my systems grew enormously with much legendary equipment to my current system which is solely sourced from audio streaming to digital output DAC, and amp listening via headphones only.

As one might expect over my many years of experience in this hobby, at every upgrade, I experienced the hope for improvement. Something I did not anticipate nor expect since beginning to incorporate LessLoss products into my system was the extent, the level of the immediate and future improvement that resulted. Such was beyond any prior experience with non LessLoss equipment.

In my communications over recent years with other owners of LessLoss products I have come to find that my experience was not unique. We have all noted that the improvement actually realized, frequently "out of the box," far exceeded the results experienced with products from other manufacturers.

In every case when an upgrade was suggested, the resulting revelatory experience was always immediate, and improved even more over time... And always exceeded what was expected. Candidly, LessLoss is a breath of fresh air in this industry of "grandiose promises resulting in nano-delivery."

Firewall Module

Date Added: 01/05/2020 by Joseph L G
I installed your new Loudspeaker Firewalls on the treble and bass modules of my loudspeakers today and then had a first listen. I really wasn't expecting to hear an improvement because my high-end shotgun speaker cables are custom matched to my speakers. But I was pleasantly surprised and wondered if my ears were playing tricks on me. As good as my speaker cables are, with the Firewalls installed everything just sounds better and more realistic. Instruments and voices are more convincing in timbre and body, with noticeably better micro-dynamics.The sound stage is as large and holographic as before, but with a more natural, more cohesive presentation. I sat glued to my seat for hours, listening to my favorite CDs, hearing delightful subtleties in the recordings that I had not noticed before. It did not matter which CD I played, it sounded better and more real. For me the Loudspeaker Firewalls are keepers.

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.

Firewall Module

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.

Echo's End

Date Added: 11/03/2019 by Greg Britton
I simply wanted to convey a heartfelt thank you!

Your suggestion that we might benefit from upgrading our EchoEnd DAC was spot on.
My family and I listen to and play music as an integral part of our lives. My original order for the DAC in 2016 was to have a DAC for my office system, but when I hooked it into our main listening system, it stayed, such was the vast musical improvement over our SimAudio Moon 750 DAC transport. The Moon was the best DAC that I was able try out at home and own over the many years, so that was saying something. I never heard a better DAC at any audio shop that I would visit so my assumption was that the original EchoEnd was best. With faith in your products having a positive musical impact, I took the leap to send our DAC back for the upgrade and wait those few weeks without a DAC on our main system. The upgraded DAC arrived at the end of September and once I hooked it back in, with no other modifications at all, simply hooked it up, and it has been incredible. Our music sounds like it has been remastered by the best studios. Just simply wow, and amazing, and also most especially thank you!

Best Regards,
Greg Britton

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!
