Firewall for Loudspeakers

The wait and the pre-order price were worth it ...

Do you practice witchcraft?

The improvement is global from the installation and is equivalent to an upgrade of electronic equipment, the gap exceeds the change of a good for an excellent cable .... !!

Received the Firewall for Loudspeakers over 2 weeks ago. Connected it to an AV system which uses high efficiency speakers - JBL with Lecleach horns (Be diaphragms) and Altec 416c bass units. All I can say is:

Bloody hell! What is happening here!! way more more resolution and impact across the spectrum!
Well done louis to you and your team!!

I now have a problem- my main system is bi- amped which means I need 2 pairs of these. I need two stereo pairs as I have a bi-amped system that is devoted exclusively to music listening (Accuphase F25 active crossover, 300B SE amp for mid highs and NCORE amp for bass).

The power supply filter with Firewall 64X power conditioning unit is just as impressive. I used the Firewall 64X to filter a power strip with my Revox B77 and Stax T1 amp and Stax headphones connected to it. The quality of music on pre-recorded and other tapes is amazing with the cleaned power supply. I am not easily impressed as I have tried various improvements such as power cable upgrade, balanced transformer etc., and achieved only reasonable incremental improvements in each step - not quantum jumps!

Ich bin so begeistert von dem Klanggewinn, dass ich es dir gleich mitteilen wollte.

Meinerseits kann ich bis jetzt nur gutes über deine Produkte sagen, schreiben und weiterempfehlen.

Meine Anlage ist nicht von den Teuersten, aber vielleicht gerade deshalb wirkt es sich so stark aus.

Nur für dich als Vergleich meine Anlage:

Musikquelle = PC
USB Transport = Mutec MC3+Usb
DAC = Meitner MA1
Vorverstärker = Yamaha CX A5000
Endstufe = JOB (Goldmund)
Lautsprecher = Jamo R 907

Gestern habe ich das Paket erhalten und gleich die Firewall-Teile angeschlossen. Du hast nicht übertrieben wenn du sagst "blown away" auch ohne Einspielzeit.
Schon nach den ersten Takten Musik merkte ich den großen Unterschied zu vorher.

Hatte nie ein gutes Quellgerät gehabt, spiele alles über meinen PC ab, den ich hifi tauglich aufgerüstet habe.

Mit den Firewall Teilen (64X; USB und nun Lautsprecher) von dir und manchen anderen Geräten ist mein PC für mich sehr Audiophil geworden.

Mit diesem Klang bin ich sehr zufrieden. Alles klingt reiner, freier, genauer, tiefer und unermüdlicher, nicht nervig.

Am selben Tag erhielt ich auch einen Mutec MC3+USB den ich nun als USB Transport nutze von PC zum DAC und diese Kombi ist ziemlich perfekt, obwohl ich am Lautsprecheranschluss, der bi wiring ist, nur Hoch-Mittelton mit den Firewall angeschlossen habe.

Wie wird es klingen mit Firewall an beiden Anschlüssen???

Gratulation zu dieser Entwicklung.

[English translation]

I am so impressed by the improvements in sound quality that i wanted to waste no time in sharing with you. 

I have nothing but good things to share about your products, and highly recommend them.

My setup is not one of the most expensive, but perhaps that's the reason the effect was so great.

Just for context, here is my system:

Source = PC
USB Transport = Mutec MC3+Usb
DAC = Meitner MA1
Preamp = Yamaha CX A5000
Power amp = JOB (Goldmund)
Loudspeakers = Jamo R 907

Yesterday I received the parcel and immediately connected the Firewalls for Loudspeakers. You were not exaggerating when you said "blown away," even with zero break-in.  It didn't take more than a few measures of music to realize the large difference from before. 

I never had a serious source. I've always played back through my PC, which I have upgraded to HiFi performance. 

With the Firewalls (64X, USB and now Loudspeaker) and some other gadgets I've managed to get audiophile quality out of my PC.

I'm very happy with the sound now. Everything sounds more pure, more free, more exact, deeper and more pleasant. It does not get on my nerves. 

Even though my loudspeaker terminals enable bi-wiring and I only connected the Firewalls to the Mid/High terminals. I wonder how it will sound if I connect another Firewall for Loudspeakers to the bass???

Congratulations on this development.

[High performance joint partnership recording between LessLoss, Boenicke Audio and Audio Consulting, implemented using C-MARC Hook-up wire and LessLoss latest Firewall technology.]

I've had a chance to listen to the recording by now, and it is really incredible - thank you!

Since I downloaded it late at night, I first listened through headphones. There, I was first struck by clarity and dynamics. But the real thing, I believe, only comes through the speakers. It is there that I really appreciated not only the quality but also the technique of the recording. It is one of the very few piano recordings I’ve heard where you almost get the tactile experience alongside the sonic one. It places you not in the audience but almost on the performer’s stool, as it were. (BTW, I have to listen more to it, but my first impression was that the positions of some mikes were changed for the second CD, no?) The middle parts of Part 4 and Part 5 are truly amazing: the way lower and higher octaves sound together, losing neither their distinctiveness nor togetherness, is, again, something I don’t think I heard before in piano recordings.

So thank you again!

Just connected the new Firewall for Loudspeakers and listened to a few songs. I can only say it's really astonishing. Everything is more real. The sound seems a bit slower but the rhythm is more correct. Listening to orchestral music feels like I'm in the hall. The soundstage is deeper, wilder. The musical instruments are more real with more texture and detail. The "Entropic" process is like magic.

Congratulations to you for this wonderful invention.

OMG! After an overnight cook-in I just sat down to some serious listening of these new speaker doobies. Well, 'serious' didn't last long as I smiled and laughed increasingly to myself, or just sat there with my mouth open. To keep it brief, presence, clarity, space and imaging are the most obvious beneficiaries so far, but everything is better. It is indeed like a speaker upgrade, but all their virtues that I loved before I just adore now. Way more obvious to me than the effects of the FW 64x, which were pretty good but I felt took a while to really bed in. Most of my (extensive) LL cables were all bought used, and obvious upgrades each time.

There's some real filtering going on as some lesser quality tracks with more digititis are better listenable, with the added enhancements already mentioned. Garbage in, recycled out, perhaps?

There's a truism of course, that it's hard to envisage further improvements in one's system are possible until something great moves it to even greater heights. But then you remember, if you already know, how real instruments and voices sound and how far there still may be to go. These FWs beat my prior Bybee speaker bullets, and to my ears have given the greatest quantum improvement in my system , excepting one major source change 3 years ago. Just. And with a bit more time on these things that may change. Thanks Louis and team. You deserve your success.

With now a complete system of Bakoon electronics and the Soundkaos open baffle Liberation speakers, I have achieved a sound that I have yet to find from anything else - and I've been to "most of the shows". And I've also played with / demoed this combination at shows like RMAF, Munich High-End, Gothenburg Audio show and Hifi-deluxe. So I know it's sound intimately and from many different settings.

This core setup already defies belief because there’s so much presence and incredible soundstaging going on - on a completely dark canvass/background.

But, I have been using Lessloss on and off (Homage to time loom + DFPC power cables) over the past many years - never letting go of my DFPCs. So I already had great respect for the brand, but it was still more out of "curiosity" and "pure fun" to see what could possibly be achieved with the Firewalls for Loudspeakers that I ordered them during the fall.

Immediately the Firewalls added “believability” / realism - where I honestly thought that I already had all of what could possibly be made in my setup. But no - with the Firewalls, I experienced more "organism" (not "body" in the usual musical terms, but instead more lifelike) to all layers in the music.

Taking them out of the system left me with a feeling of disappointment and disbelief - that something I knew so well (and had loved) could be given such a small tweak (both in size and cost) to make such a big difference. So of course it's there to stay. But it also means that there are more Lessloss products coming my way soon.

Good day,
LessLoss firewalls for speakers are now playing in my music system.
I was convinced that the LessLoss products are very good.
A friend of mine has the cables in his music system and is also very enthusiastic.
Already the first few minutes, my Harbeth 40.2 equipped with the FireWall makes music like never before.
The music sounds very clean and transparent. But the music doesn't get annoying.
The music fascinates me a lot more now.
An excellent result that I did not expect.
For me, the firewall is essential.
I downsized my music system and no longer wanted to invest in high prices for cables and power cleaners.
Before the LessLoss products, various high-priced cables and cleaners from Schnerzinger, Stealth Audio Cables, Shunyata, Audience, Yamamura etc. were used in my previous music system.
Given the fantastic performance of the FireWalls, I no longer look back at the cables and cleaner I sold.
But on the contrary. I am very happy to now own the firewalls that are absolutely worth their price and offer excellent musicality.
I recommend every serious music lover to test the FireWalls in their music system.
I hope that the three-axis C-Marc speaker cable and the RCA cable I ordered will arrive soon so that.
It will be a feast for my hearing.
Thank you very much and good luck.

First of all, I would like to thank you for the excellent cable and speaker firewalls and for the excellent customer service.

Now the RCA and triaxial speaker cables are also playing in my music system.
Although the cables haven't yet played music for long, I am already enthusiastic about the musicality.
For me, the cables and speaker firewalls are an absolute must in my music system.
Without this, I miss the tonal substance, the timing, the fine details and the musical energy that are so important for my perception of authentic music.
The music now sounds even more powerful, dynamic and homogeneous.

With these unique cables and FireWalls I have the feeling that I can fully exploit the potential of my music system (LDMS server including Ideon Audio 3R Master Time, Lampizator SE GG 2.5 Pacific Edition including preamplifier, NAT transmitter, Harbeth 40.2, etc.).
In addition, the cables and firewalls are very meticulously and precisely manufactured.
My eyes are spoiled too.

I am very happy that I chose LessLoss!
Stay healthy.

Thank you very much and good luck.

This cable was the BEST purchase that I've ever made!! I’m not affiliated with this product in anyway, but feel sorry for Audiophiles who don’t purchase these cables. Once Audiophiles try this cable, they will wonder how this product can be sold at such a low price. I’m baffled… In an industry full of snake oil, unethical cable retailers, enormous profits and scams - this LessLoss "Filtering Power Cable" is a "breakthrough product" which blows away the ALL competition at ANY price!!! I honestly don’t know how LessLoss can make a profit while using Oyaide connectors, hand braiding and an incredible passive AC filter. LessLoss "Filtering Power Cable" are sold from a manufacturer /owner /designer who is trustworthy, ethical, knowledgeable, and a pleasure to deal with. Take a chance!!!!, PayPal your money to Lithuania - and you'll be rewarded with great Customer Service, and the finest power cord made. Hear for yourself what you are missing!!! Thanks Again!!!
