Firewall Module

Date Added: 12/14/2018 by Colin Gray
Over the many years (40+) I have been improving my system, it has been said to me many times, by people in the industry, that you can have all the ‘boutique’ components you can inside your equipment, but unless the power supplies are the best possible, these components are a waste of money.
Some years ago, I added 4 of the original DIY Firewall modules into my system and the point made above was proved yet again to be true. On news of the latest generation 64X version, I placed an order for 4 units. Not to replace the originals which are still in my system, but to be additional to those.
I read all the positive reviews of those who had their units before me and this only added to the frustration of waiting.
However, it was worth the wait! Yes, they do need significant time to burn-in, but these new units are simply superb. I won’t repeat what others have said, simply take it as true and in no way exaggerated.
Last year I upgraded my amps to Gato PWR-222s and this brought about a tremendous improvement in SQ. However, now feeding the AC power to the amps through the Firewall F64X has brought about a bigger improvement in SQ than the amps on their own did.
I have absolutely no doubt that any system, no matter how expensive, will sound better if the power is fed through a Firewall 64X.

[Custom power distributor, solid oakwood housing, four integrated Firewall modules onboard, C-MARC internal hook-up wire throughout, six European Schuko outlets.]


I have had the unit a few weeks. I am listening to it now.

I am genuinely astounded how much difference it has made. My system was already very resolving, but it is now astonishingly good.

I feel I can actually ‘see into the mix.’

Were you to know my views on audiophile product marketing and spurious science being used to sell kit, you would understand how odd I sound to myself. I just heaped hyperbolic praise on a mains filtering distribution block.

I was genuinely unaware that something so relatively 'low tech' (from the perspective of the rest of my kit) could make such an astounding difference.

Now insanely fast, ultra resolving with fast, tightly controlled bass that moves stuff.

Unequivocally recommended.


Thank you.

Thank you very much.

I have the KEF LS50W active speaker system which is a speaker with built in amplification, DAC and streamer. I ordered qty:4 of the 64X Firewalls (2 on each speaker) and it has completely transformed the system as if I have upgraded components and also larger speakers. That fatiguing sound of digital audio is gone, rendering an organic, more lifelike presentation with a much bigger soundstage. Try at least one. It goes to show that good power is paramount in quality sound.

I received my first batch of the 64X units and after a week of daisy-chain hookup to a FryCorder2 I replaced all my 1Xs and 5Xs on my main system with 64X, so now every component has a 64X at its power input. I really did not expect to hear any change, but I did, for the better. Every track I play sounds cleaner, clearer, and more tonally correct. Whatever those little wooden boxes are doing, it is remarkable.

Installing the Firewall 64X into my system in May 2018, I noticed the immediate emergence of subtle cues that had previously been inaudibly submerged beneath the parasitic noise "riding" the current into my audio system. Of course, as one would expect, those cues infused the musical presentation with a latent natural delicacy only hinted at previously. In my system (Oppo 105 --_ Music Reference RM-200 --_ Magnepan 3.7s), I found the most benefit when used in conjunction with the tube amplifier.

One major (and somewhat embarrassing) ancillary benefit was that the increased resolution, arising from the installation of the Firewall, permitted me to reposition the speakers with greater precision. The synergistic results have been most enjoyable. Throughout the audio spectrum there is greater focus, as well as, a more cohesive soundstage. Bass is more tunefully solid, highs are naturally airy and crystalline, and music flows with greater harmonic richness and nuance. These improvements have been more fully realized with usage.

I have placed an order for a second 64X.

Received my first Firewall 64X about 2 weeks ago and I’m really happy with what it did for the sound.
The results are amazing, more natural sound and more of everything.

Well worth your money!

Since almost three weeks now, the 2 Firewall 64X that I have ordered are burning in, respectively on the cd player (Accuphase DP-430) and on the amplifier (Accuphase E-370).

They have replaced two Firewall 5X that have replaced the first version of the Firewall.

After about 50 hours of irregular play and unconvincing results (‘bloated’ bass and loss of details compared to the Firewall 5X), the sound started to change rapidly when I left my system on almost 24/7 during a long weekend.

To cut a long story short and after around 250 hours, this is probably the best product you came up with since I first started to be a LessLoss customer.

Over the last 6 years, I have purchased three DFPC power cords, upgraded to DFPC Signature, HTT cable loom, C-Marc power cables upgraded to Super C-Marc cables and C-Marc XLR interconnect and speaker cables and, as mentioned, the various forms of the Firewalls in-line conditioners.

And let’s not forget the distributor you made for me.

Each of these products was a clear upgrade compared to its predecessor (expect maybe for the HTT interconnect and speaker cables that never really and/or fully convinced me or simply because the interconnect and speaker cables they replaced were probably very good, albeit much more expensive).

But nothing prepared me for the upgrade that the 2 Firewalls 64X brought to the sound of my system.

I never heard it sounding so dynamic, detailed and powerful.

Bass is out of this world: slam and ‘finesse’ at the same time and perfectly balanced with the rest of the music that is now clearly more detailed and ‘richer’.

The level of improvement that these two Firewall 64X bring to my system is simply stunning.

The Firewall 64X that I received a few days ago replaced the 1X that I used on my passive power distributor.
Now I have re-read all the comments by other users of the new Firewall. What can I add?
I can only agree to all statements I see made by others. The 64X got me a big, big improvement in all aspects of sound imaginable.

There may not be a big improvement on the Echo's End Reference DAC, as it already has three of the 64X modules inside, so this fantastic shift in quality can be attributed to the clean power going into the Pre- and power amplifier. Even if I thought that my system sounds excellent with only the 1X installed and the wonderful Echo's End Reference DAC, I asked my neighbor to take a listen to prove I am not just imagining things.
Yes, it is a revelation!

The new module made the biggest improvements again on the jet great sounding discs. I searched and dug out a lot of discs that came with a flat, boring or distorted sound. Mostly these discs sound even more miserable, flatter, with a total collapse of soundstage, when played with really very expensive gear.
But again the Firewall 64X make it a much more comfortable listen, coming with more depth, room information and details. So those discs, collecting dust over the years and stayed unplayed on the shelves now get a re-listening. Distorted guitars are still sounding distorted, but with the Firewall 64X the music is no longer biting into my ears.
The sharpness that makes the listening uncomfortable is gone without a loss of details (there is more instead).

That only one Firewall 64X installed can make such a profound difference is amazing, when you consider the modest price for it.
How much money must someone invest in gear to get such an improvement? Or is there anybody out there who can name gear, a tweak, whatever, that comes with such a jump in sound quality?

Everyone who wants to build a system with, well, even only 3,000 EUR on hand, should calculate with the investment of one Firewall 64X module.
It is simply essential.

I wish that there will be someone who can compare two or three of the Firewall 64X modules, one C-MARC power cable going into a modest priced, passive power distributor of good quality with the Audioquest Niagara (10,000 EUR), the new one from Transparent Audio (15,000 EUR) or any other distributor in this price range or above. Let’s hope that this happens in the future. That would surely become a fascinating listening session.

In my opinion the Firewall 64X is the biggest bargain in high end audio equipment in a long long time.
Everyone should have at least one of it. :-)

Looking forward to coming rave reviews...

Liudas, thanks a thousand times!

This brief review is for the brand new, hot off the line, the 64X Firewall. Louis let me trade in my older very nice 5X Firewall for the new 64X. I was wondering how much an upgrade the 64X would be. After all the original 1X Firewall and the improved 5X Firewalls each were very, very nice improvements! How far could this go? With just one 64X Firewall? On my amp? Well, actually, without exaggerating, I was surprised. Way more improvement than the 5X Firewall was over the original Firewall. Striking gains in clarity, depth of the soundstage and delineation of instruments. When two oboes or flutes are playing the same notes, you hear both instruments distinctly! When a French horn is playing (often to the extreme left) and the trombone to the right, you hear each instrument, with it's own timbre and tone and can enjoy the spatial and tonal differences between them. This with just one 64x Firewall. Wow! Anyhow, I've very much enjoyed the new toy in town and have stayed up late at night listening to old pieces to hear them anew! Honestly! I'm a long time LessLoss buyer and very often I am constantly surprised how these young, hard working Lithuanians are so resourceful! I'm 100% convinced that I'm getting great value for my money. For sure I'll be getting more of the 64X's....... One last thing: my friend, the retired medical professor, visited my home and heard my system, filled with LessLoss cords and Firewalls and he has just purchased all his power cords and a specially made LessLoss distributor filled with five 64X Firewalls.

Got my Firewall 64x module a few days ago, cooked it on an FM tuner for 24 hours, and auditioned it the afterward on my SACD player, replacing 3 daisy-chained 1x modules. I was blown away by how much clearer familiar tracks now were, and with extended treble and bass as well. I assumed I'd hear some difference, but I never expected it to be so dramatic. After a few more days of break-in, the sound is a bit smoother and more natural. A fantastic product! I want more...
