I've noted the Firewall with 4 stars, since a new good product can always take its place. Louis Motek's splendid Firewall did something very important in my system. The sound transformed from an artificial and rigid timbre into a more relaxed solid, organic one. More controlled lows, natural mids, and silky highs. That sometimes metallic spectrum is gone. And when you see the Panzerholz shield of the Firewall, you feel very proud of this product. Note: it works splendid with the DFPC Signature cables. Thanks, Mr. Motek.

This will be of interest to owners of the original Firewall as well as new customers!

I wanted to express my highest praise for the redesigned Firewall. My system now employs everything LessLoss has to offer with remarkable results. I have had the opportunity to listen to my system evolve over the past 3 years as I have added LessLoss solutions to the point that despite having 15 year old speakers and amps, I am listening to something beyond my wildest dreams!

What I now hear rivals systems I have heard costing 2 to 3 times more than mine. The final solution was to add the redesigned Firewall, but since I am using the original Firewall, how could I best use the new one? After experimenting with various configurations, I found the best sound was obtained as follows: Dedicated wall outlet to DFPC Signature to New Firewall to DFPC Signature to the Old Firewall to all other components. The addition of the New Firewall further stabilized and defined an already wonderful sound stage. The listening experience is 3D! It is so life-like it is almost scary. I can hear so far into the music, it is like I never heard these CDs before. A note of caution when first adding the Firewall; be prepared to allow for some serious break-in time. Even after 200 hours of listening, I am still hearing subtle improvements in the sound. I am hearing almost no digital/electronic noise which is so common in solid state systems, even when playing complex and dynamic symphonies (i.e., Gustav Holst's "The Planets"). Every kind of music from pop, to rock, to jazz, to vocals, to classical sounds wonderful. I get so lost in the music I can't even concentrate to read.

Thank you so much Louis and Vil. Your products are the best!

My system:

Mac Mini
Transparent Audio USB Cable
Ayre QB9
HMA Sestetto Cable
Octave HP500SE
HMS Sestetto Cable
ADAM Audio Pencil Active Speakers
ALL Power Cords Lessloss Signature
3 Lessloss Blackbodys

I have a dedicated power line with a special grade fuse in the power distributor in our house. The wall receptacles are from HMS. A DFPC Signature is feeding the Firewall. Another DFPC Signature is feeding a Furutech TP609e. From there all other gear is fed by Signatures. Before buying the Firewall, the system was fed by a HMS "Netzleiste", which is something like a classic in Germany. I still use it for the mini, which seriously hurt the sound when being plugged into the Furutech.

Before going into the details, I have to confess that I am biased. I was completely overwhelmed by the naturalness the Signatures introduced into my system. I started of with one cable for the QB-9 which gave the QB-9 more weight, more flow and even more naturalness. I then bought cables for all my other gear. But I still had the HMS distributor between the cables and the wall receptacle. It never did hurt me. Then I read about the Blackbodies and bought 3 of them. As with the cables, they did exactly what Louis had told me. They gave my system a clarity and see through quality I didn't think was possible. My system sounded good without the Lessloss products but it sounds excellent with the powercords and the Blackbodies. Well I am an audiophile. So I kept thinking about the firewall, with the most positive bias one can have. I expected nothing else than the biggest upgrade I ever made to my system. So my expectations where very, very high.

When getting the Firewall I was impressed by its size and its looks. I thought "Damn, why does this thing have to hide behind my rack?" It is big and heavy, and the looks of the Panzerholz are striking. Before getting the Firewall I had some longer email conversations with Louis and he advised me to set the Firewall up exactly as written on the LessLoss Firewall page (there is a separate PDF Firewall Usage Guide to download). I did this and started to listen to music. Well, to say I was disappointed is putting it very mildly. I knew my system had to warm up (the QB-9 takes some time when it was off the grid and my Octave Pre has an external power supply which usually takes at least 5-6 hours to reach its peak). But I have heard my system cold before. When I leave the house for a week or longer I take everything off the grid. But it never sounded this bad - at least I thought it sounded that bad. After listening for about half an hour I turned down the volume and turned on the TV. I slept really bad that night. The next day I thought, well I heard about burn in of the older Firewall, which was supposed to take weeks. When I got back from work the next day I listened to some music and it was sounding better. Even better then before. But not 4000 Euros better. The sound was thin, but the dynamics where very good, quite was quite and loud was loud. But after an hour I got tired of the sound. This was a really bad sign. So I emailed Louis who confirmed that there was burn in time and it should be much better the next weekend. So I slept a little better that night. The next day I invited my brother, who is a recording engineer and also an audiophile. My wife and kids were not at home this night, so we cooked something, had some wine, talked a little and had the stereo in the background. It sounded good. It sounded very good. So we sat down and had a listen. First was Mahlers 5 (Gustavo Dudamel, Deutsche Grammophone). I turned it up a bit. I turned it up some more. The orchestra reached a peak and the whole room was shaking, I felt the sound and I had goose bumps all over my body. My brother looked at me in disbelieve and I had a grin all over my face. I didn't say anything, but kept thinking: "what the ****, what the ****, "The dynamic range of my system had increased in a way that I thought not possible. The control over bass was extraordinary, we could turn up the system to a point where the active speakers went into safety mode and up to that point we always felt that the system can easily handle it. My brother kept saying "This is phenomenal, I can feel the music, this is almost like life….". We heard music, drank wine, drank some more wine… I went to bed happy and drunk and thought what a good investment. Until next evening.

I listened to my system and something had changed. It had lost some weight, it sounded thinner, but there was a new quality to the sound. It had top end sparkle, it produced pictures of an enormous size. Wow-… but after an hour I got tired, listening fatigue. I emailed Louis and he said that it is very probable that you will experience "performance bumps" while the unit burns it. But it should be better next weekend. After the experience the night before I couldn't wait for the weekend to come.

Well I could write about the next week and a half, where I experienced two more bumps, but I'll skip over that. All I can say is, that burn in is lengthy and painful. Louis wrote that he can hear some 90% of the good things right away. I would say that I heard about 60% at the beginning, at maximum.

How is the sound now?

On the website it says that you will experience dynamics floating around freely. This is the exact truth. My system is utmost dynamic. It is impossible for me to listen to classic orchestral music in the background because most is too dynamic. The other day the UPS man rang the doorbell, heard the music and asked me if we were artists. I asked him why he thought that and he said, because I had friends who made such great live music at my house. At first I thought he was making fun of me. He really thought I had a jazz combo playing live at my house. Afterwards I understood, because the music has a natural quality with the Firewall that exceeds the naturalness the Signatures impose on a system by far, very far.

Talk about details. If you want to, you can get lost in finding new details in records you thought you knew very well, because you heard them on a lot of very different systems. For example "A case of you" Live by Diana Krall. I always hear some coughs in the audience. I thought it was about 5 or 6 (I can't remember). With the Firewall in place you hear a plethora of coughs. You even have an idea where in the audience the people who cough sit and I think I can hear which coughs are by the same persons. But this is not important. Important is, that the emotional quality of my system is so much better than before, that I constantly get goose bumps and I am usually not a very emotional person. Something more related to music. ;-) You can easily hear the decay of a triangle while the whole orchestra is playing.

You can easily hear every detail there is (so it feels) but you don't have to. Just don't. Just listen to the music.

Talk about bass and energy. Listening to a bowed acoustic bass (I don't know the exact translation of "gestrichener Bass"). If you ever heard one just beside you, you know how the bass can make your body vibrate. You feel it at you sternum. The bass in my system has become exactly this quality and the ADAMs are good with bass but not really great. I know a lot of speakers which can do better in that region. With the Firewall it is like having a very good active subwoofer in my system.

Talk about color and resonance - exceptional.

Talk about speed, rhythm and interplay of instruments. On good recordings (mostly old ones - very sad!), you hear the interplay of the band.

Talk about highs - cymbals and hi-hats to die for. Attack, shimmer and resonance - wonderful. Top to bottom extended in a way I have not heard before.

Are you into computer audio? If so, you know about different players sounding different. I have never before so easily discerned the sound signature of the various players. Just for the fun of it I changed one of my interconnects to my old interconnect (not a cheap one!). I remember that I could hear that they sounded different, the one I replaced was good sounding but did not have as much air and did not have the same emotional quality of the HMS Sestetto. Changing the cable back was like listening to a broken system. The degredation of the sound was dramatic. I now knew why I did not like these cables.

So, is the Lessloss Firewall the most dramatic improvement I ever had in my system? YES. Is it worth the cost? Yes. It is a lot of money, an awful lot of money. But to bring the investment into perspective: I had very expensive cables in my system for evaluation and they would have cost almost as much as the Firewall and they did not bring this much improvement.

What others say: in the meantime 5 other people have heard my system and where from deeply impressed to shocked at the improvemt. I will now invite my dealer who sold me speakers and my pre to let him listen to my system (the other day I took the Blackbodies to his place and he was impressed with the results). My wife said: This is really moving sound. My kids either say: "Can we listen to some music?" or "Turn down that music it is too loud." or "Turn down your music and let us listen to our music." I can now even enjoy some kids' music.

But most of all I am on a mission. On a mission to rediscover all of my digital albums. I can't wait to listen to my 1000 LPs. So I have a lot to do. But then again. Maybe I'll listen to these new interconnects from this Lithuanian guy? ;-)

Caution: if you buy the Firewall, then don't let it sit on thick carpet. Make sure that the Firewall sits with its 3 tiny spikes on something hard. Experiment with placement. I put some resonance control devices under the little spikes. With great result. If you do not place the Firewall properly you will not hear the full potential! And: expect about 10-14 days burn in. AND: once burned in is not always burned in. I accidently unplugged the unit and had to experience it the hard way. This is the only thing where you should not trust Louis: the sound right out of the box can be very frustrating. So if you don't like the Firewall, wait for a couple of days and you will know where the sound will be heading over the next couple of days.

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!!!
