5X Firewall Modules

I would like to share my experience with fully burned-in 5X Firewall Modules in my system, which already includes LessLoss Signature power cables, Homage To Time IC, the Echo's End DAC and 1X Firewall modules. Like all my cables, they were burned in on an AudioDharma Cable Cooker for a full 7 days which, with daily testing, I have found to be necessary to achieve optimal performance. I must repeat again that I'm no tech expert but merely a music lover of long standing.

Starting with just a single 5X Firewall Module, I found the greatest improvement when installed on my amp rather than the source (CD-player) as suggested by Louis. Once again, the sonic improvement was clearly incremental to the already significant gains from the LessLoss components already installed. I decided then to have 5X Firewall modules for every main component (CD-player, DAC and amp) and the end-result was certainly worthwhile.

It is difficult to describe the improvements to a system that I'm already very happy with but it would be best summed up by the word "Refinement", added to descriptions like "black" background with no noise, deep and wide soundstage, realism and great dynamics, natural refined bass and superb definition and clarity etc. Poorer recordings, particularly old definitive ones like Otto Klemperer's Beethoven symphonies and others, have been given a new lease of life. Bass quality, in particular, has been greatly enhanced; Rebecca Pidgeon's "Spanish Harlem" (a highly recommended audiophile recording) demonstrates this superbly, coming through sounding so natural and with great definition, yet not boomy or distorted.

My journey to achieve better sound with LessLoss components (a company with whom I have no ties) began with power cables and progressed to include the other components referred to above and it has certainly been a very satisfying one. As a music lover first and foremost and an audiophile for over 40 years, I am now enjoying my music more than ever.

Dear Louis,

Even if the full loom of C-MARC cables and the new distributor (and 3 Bindbreakers, under the distributor) have only a mere 30 hours of play, I can already tell you that it is taking music to new heights.

I can't comment about a single cable in particular (XLR interconnect, speaker cables, bi-wire jumpers and 3 power cables, new FW-based custom distributor and Bindbreakers) as they were all connected together at the same time. But what I hear right now is astonishing.

As much as I have enjoyed the DFPC power cables (Original first, later upgraded to Signature) and the HTT interconnect, etc., the full loom of C-MARC cables and the new distributor (and two previously purchased 5X Firewalls) bring the sound of my cd's to an entirely new level.

I will wait for the C-MARC loom to reach the 100 hours mark before posting further impressions, but so far, I have only one word: 'Wow!'

======

(after 100 hours)

Things keep on evolving very nicely indeed, Louis.

It is almost frustrating to realize that so much information was somehow lost or buried during all these years, including 'the LessLoss years' when it all started with a couple of DFPC Originals.

About 100 hours of play and the music sounds extremely rich ('creamy'?), smooth but very detailed, powerful and engaging.

Each cd reveals more layers of details and the C-MARC loom keeps all its promises.

When I decided to participate in the early bird program, I have to admit that I was skeptical about the principle of purchasing an idea, a concept and not a finished product.

I am very happy that I seized that opportunity!

You were right: C-MARC is a game changer.

=====

(after 400 hours)

Although I feel that burn-in isn't completed yet, I wanted to inform you about my most recent impressions of the C-MARC loom after around 400 hours.

Everything I mentioned before is confirmed in a splendid way: details, presence, 'kick', powerful bass, extended treble, etc. etc. etc...

This is way above the level of my DFPC Signatures and HTT speaker and interconnect cables.

When I return to my previous comments about these cables, it could potentially appear that the level of improvement that the C-MARC loom has brought is 'not believable', 'over enthusiastic' or worse, solicited and/or paid for.

The extent of the improvement brought by the C-MARC cables is nothing short of dramatic.

And as my 'main' components haven't changed over the recent years (Ayon cd player and amplifier, Sonus Faber speakers), I can comfortably 'feel' and hear the upgrade brought by the C-MARC loom. But owning tubes components, I have to say that burn-in is a pain... I wish I owned a second system to which the cables could be connected to for 500 hours. Witnessing the burn-in can be perceived by some as a nice process but not for me.

Luckily, my patience was rewarded (and in this case, the upgrade was obvious even early on in the burn-in process).

Being familiar with your cables, I am quite sure that the sound will still evolve in the course of the next few weeks. I don't think it is useful to try to go deeper into details; I am not a reviewer and not even an audiophile.

But I can say that once again, you came up with a fantastic series of cables that clearly outperforms anything I owned previously, including much-loved LessLoss cables.

Black magic! Improved timbre, body, darker background, more extension on both ends. Highly recommended without reservations!

Louis is very responsive and friendly to interact with as well. Keep rocking!

I also built a home made power filter using two stacks of 3 'naked' Firewall boards each, and got the plug-and-play Firewall 5X and one USB Firewall Key. I also got one DFPC Signature mains cable for the Firewall filter. They all work perfectly together and give a huge improvement in more silent background, a bigger soundstage, clearer and deeper bass, and an increase of the organic natural aspects of the sound. All this is achieved by killing noise. I simply can't listen without this product in my setup. This is an unbelievable high-end extension in so many ways!

I am deeply impressed by Your knowledge and development of noise and electro magnetic radiation suppression. Your products are truly superb. Yes it costs some money but I personally do not regret it. This is my best additional high-end investment!

With the LessLoss power distributor (with 36 Firewall module) & C-MARC power cables, they significantly reduce HF noises generated from my audio system (normally I could not listen to music from my system longer than 2 hours). After I use the LessLoss power distributor & power cable in the system, it was so unbelievable that I could listen more than 4 hours with the new experience of music from my audio equipment. It is far, very far beyond my expectation. It's just simply PERFECT for me!

I have a system powered by a custom distributor from LessLoss, internally wired with C-MARC hook-up wire and equipped with 4 pcs of the new Firewall 64X. As powercables, I use LessLoss C-MARC throughout.

The power system has now played some 300 hours and the resulting sonic performance is striking. The noise floor is extremely low with a background that is pitch black. The perspective and depth is very clear and pronounced. Texture and microdetails at all frequencies are coming through with wonderful resolution. In short, music is being played with great emotional impact.

In my opinion, there is no other part of a HiFi system that can be improved as much, with the limited cost involved.

First impressions of the new FW64x.
Note: I used the first FW1x and upgraded to the FW5x when they became available and now to the new FW64x.

I replaced 2 daisy chained FW5x that I had on a Torus Power which powers the whole system with one FW64x.
Wow, what a difference!!!

The FW64x unleashed the music, beside being more quiet, cleaner, smoother, flow easier, it is more real sounding and let the energy of the music flow with what seems to be with no restriction. You can hear better the start and stop of notes. The instruments and voices sounds much more like the real thing.
It is more dynamic with great PRaT which makes the music more fun to listen to.

It's like the FW5x held back the music. which obviously one can't tell until hearing the FW64x...

It extends both sides of the frequency range, making the bass goes deeper and fuller and the highs, well, higher, with lovely sparkle to them.
There is a better grip of the music and more presence.
And all of these with much more emotional involvement.

When adding a couple more, one on the music server and one the DAC, you get everything described above to a much higher degree, really put a smile on your face :-)

This upgrade is much more significant than the upgrade from the FW1x to FW5x, and you can immediately hear it.
I'm very happy with it !!!

I replaced my first and second generation Firewall modules with this new (64X) version. I was quite satisfied with the previous ones and I hoped that one of 64X could replace the 2 I had with some slight performance gain. It is not a slight improvement. Even only using it for a few hours it is an obvious significant improvement. One aspect is completely unrestricted dynamic behavior and that I expected just from seeing that it is a much higher gauge construction. The noise floor dropped a lot which becomes most obvious if one listens to how a note decays. Now I can hear how piano but also other instruments decay and fade (and even subtle tonal changes during the decay). This is not buried in background noise. It became quite obvious when the last note in a recording got truncated (it was likely not obvious during mastering with higher noise floor equipment). The Firewall 64X does not edit and change the music, only removes noise which is masking the natural sound.

Firewall 64X: FIRST IMPRESSIONS

Having been a long-time fan of LessLoss’s superb products, I presently have their DFPC Signature and the C-MARQ power cables,C-MARQ interconnect, the original Echo’s End DAC, USB Firewall, and the 5X Firewalls in my modest system (Response Audio’s RA-801 tube amp and RA-100A tube CD player / and a highly-modded PrimaLuna Prologue Premium integrated amp), I have come to expect incremental sonic improvements with each addition or upgrade of their components. I am first and foremost a music lover and at this stage have been very happy with my system and enjoying my music. I should declare that I have no commercial interest or any ties with LessLoss.

I was therefore not prepared for the jaw-dropping sounds I heard after installing the new 64X Firewalls which had undergone only 15 hours of incomplete burn-in. I’m no professional audio reviewer and will therefore use my own simple descriptive terms.

I was simply astounded by the fluidity and ease of the flow of sound against a very black and silent background while the top-end sounded sweet and clear with no harshness and bass was superbly natural without any ‘boominess’. Everything sounded alive and dynamic yet natural with great depth, wider extension of both ends of the audio spectrum, spatial orientation and soundstage; female voices sounded exquisite and musical instruments sounded ‘live’ in good recordings. Close your eyes and you cannot place the speakers.

Some of the tracks I often use for testing include the following:
(1) Liszt’s “La Campanella” (Yundi Li – A Portrait) – you can hear the crystal glass-like ‘plinking’ sound of the top notes at the beginning of the track and distinguish practically every note played.
(2) Beethoven 5th Piano Concerto (Wilhelm Kempff –DG from the early 1960s) – Even such an early recording and my favourite version can come to life, especially the piano.
(3) Duet from Delibes’ “Lakme” (Lesley Garrett) – the clarity and spatial orientation of voices.
(4) The recently released remastered album “The New Sound of Maria Callas” – sounds more like a recent recording.
(5) Wagner’s “Ride of the Valkyries” (Die Walkyrie) (Solti’s original 1960s Decca version)
- Takes you on a ride with the Valkyries.
(6) Beethoven 5th Symphony (G. Solti – Decca 1988) – experience the uplifting power of the final movement
(7) Vivaldi’s Concertos for the Emperor (Harmonia Mundi). – the strings in this recording often sound harsh and brittle in most systems but now sounds sweet and ‘tamed’.
(8) Cecilia Bartoli – ‘The Vivaldi Album’- listen to her incredible vocal pyrotechnics
(9) Rostropovich playing the Bach Suites – relish the” bite” of the cello’s glorious sound
(10) Diana Krall – “Temptation” from ‘The Girl in the other room’. Listen to the clarity and metallic timbre of the cymbal and of course, the wonderful husky voice of Diana’s.
On track 9 (‘Narrow Daylight”) – you can hear what real electronic guitar “distortion” is all about.
(11) Frank Sinatra – Track-8 from “Nothing But The Best” album:
(12) From a collection of test tracks including the best from Chesky’s collection.

The 64X Firewalls have been returned to the AudioDharma Pro Cable Cooker for full burn-in. I can anticipate further improvements. IMHO, I honestly reckon the 64X Firewall would simply be the single most effective component when it comes to sonic enhancement for any decent audio system.

Of all the LessLoss products, the Firewall 64X is the one that has singly produced the greatest sonic improvement, at least to my system, bearing in mind I have all the other components already installed.

Thank you so much for this new Hifi experience!!

Opened the package before my birthday … just to burn in on time :) … and will be celebrating now for many days to come, far beyond the 27th :)

So much more reality, the closest to musicians in my living room!

The soundstage widened and everything is placed more precisely with more space between.
Everything seems more fluid and easier to listen … again possible to play louder, without instant tinnitus alarm.

Dynamics are excellent, e.g. plucking strings and percussion. Less aggression, but more punch … contradiction?? … regardless, I heard it like that.

Bass is richer, deeper, more powerful and precise.
Improved textures and details I never heard before!

I could hardly stop to play more and more. Had to try on all my albums to see if it works on all, still wanted full length of each to enjoy … so very time consuming :)

Finally, when I put on the Holst Planets Uranus (Seiji Osawa, Boston Symphony, Decca 1979), I got goosebumps all over my body and watery eyes. It was so real and close … even though the recording has some ground noise.

All this was very amazing, after already having tweaked the hifi power with quite some efforts: new fuse box with exclusive phase and melting fuse for the hifi, with direct special cabling through the house, many parallel filters and other “informed obsidian voodoo” (Vortex Hifi).

Still hoping for the burn-in to melt the occasional high sibilant sounds, especially with female voices. With everything else so smooth, they stick out more. But depending on the recording, there might be none anyway.

Just had another impressive experience with good old Andreas Vollenweider, Caverna Magica … The stage is not only wide but it has a clearly defined end, which does not have to end at the walls of my living room!! And every one of the instruments sounds so much more natural !! Just love this !!

Funny, that this 3D effect seems to get stronger, if you leave your sweet spot for a minute and then return. My brain seems to adjust to the new standard quite fast and you have to show again, that it is so much more than ever before … :)

Very, very happy with your firewalls 64x !!!

Thanks again, Louis. A wonderful invention and very nicely packaged !!!

Best regards, all the best,

Joerg

PS: The delivery was impressively fast with 24 hours!!

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.
