Firewall Module

The firewall has been nothing short of amazing! I am still listening to CDs and a dedicated dac but the music come through with no external noise. The strange thing is that before the firewall module, I knew my system did a good job of suppressing noise but the firewall module takes it to a different level. The music is extremely dynamic. All ranges are effected. The bass is solid and the treble on piano is exquisite. The. mid range is lifelike. I had a friend over to hear a recording and his comment was that the musical background was dead silent. He said that what we were hearing was better than what you would hear at a live performance in an auditorium. And I have to concur. For the record I don't have a state of the art system but the equipment that I do have is older but very good. Moreover, most of it has been modified. I have a another friend who is an electrical engineer and he builds amplifiers for recording studios. we have taken an older Jolida 100 watt tube amp and changed a number of the components to achieve a higher performance level than the typical amp. I use a custom full range Electrostatic speaker that could be put together by an advanced hobbiest. And of course its modified with the additional of a taket super tweeter and two Gallo subwoofers (also modified in the solid state amplification). With electrostats the mid range is always excellent. But I can truthfully say that now it is truly lifelike! There seems to be nothing between you and the performers. The sound stage is perceived as a physical dimension that extends beyond the walls. And depending on the performance the vocalist is right in front of you at a specific height and depth. I couldn't be happier with the firewall. It really provided that little bit of extra that enhances the sense of realism!

A friend's son who teaches at MIT (Massachusetts Institute of Technology) told me about these products from LESSLOSS. Per the instructions of Louis Motek, a principal of this operation, I have tried, and purchased the DFPC skin filtering power cables, their Firewall current conditioning units, and their Tunnelbridge distortionless interconnect system. Collectively, these combined systems are not cheap, but combined they exceed the noise and distortion reduction of anything I and some friends have tried at any price even up to six-figure US dollars, and which ultimate systems exceeded the cost of the LESSLOSS system.

My current system, because of my age, and for my convenience, is now a computer operated headphones only system with Stax SR 009 phones, the Weiss Engineering Medus D/A and the WOO Audio WES headphone amplifier.

The current conditioning modules with the DFPC cables immediately and dramatically increased my system's dynamic range. Using impact as a reference, dynamics went from a pat on the back to a "slam" on the head! In sum, everything together the so-called "black background," depth and exceptional realism of the venue can almost be frightening if you are not familiar with the score.

Is it worth the value? No, I would say it delivers even more than I expected. As soon as I put the new LessLoss Firewall into my system, details just came out, and more musicality. Works great with my Saec TapCute6 Pc-triple C power distributor with Entreq Olympus hooked up at ground binding post. The result is more than words can describe. A Must Have!

Firewall Module

For a long time I have struggled with the deleterious effects from noise-laden mains, making costly high end equipment underperform, sounding lean, harsh and flat. I have tried filters, but found them to influence the sound, specially in reducing dynamic performance. A while ago I found a very good solution in combining Less Loss DFPC Signatures and References with a couple of QRT Qx4 power purifiers, pluss two QV2 line harmonisers inserted in the Qbase QB8 power distribution unit.

Then came the new Firewall Module on the scene. I wondered if it would be overkill, but I wanted to try. So for the last week now I have had four Firewall modules in the line - one for the QB8 power distribution, the other three connected to the DAC, the pre amp and the power amp. So was it overkill? Not at all! The enhancement in the overall sound quality and listening experience is in fact astonishing. The music is presented significant more dynamic, instruments and voices have got more natural body and timbre, and the soundstage appears deeper and wider. Most important for me: A stronger connection with the music emanating from my speakers, it is another step closer to live music, and I just have to listen into late hours.

For those concerned:
Digital sources: MacBook Pro with Amara software, streaming to a BelCanto REFLink usb-s/pdif adapter.
Dac: Hegel HD30
Preamp: Hegel P30
Power amp: Hegel H30 (one, in stereo mode)
Speakers: Audiovector SR6 Avantgarde Arretè
Digital cable: LessLoss DC, Signal cables: Nordost Tyr2, LessLoss Anchorwave, Speaker Cable: LessLoss Anchorwave

As the owner of four (4) DFPC Signature and Two DFPC original power cables I am familiar with LessLoss innovative Dynamic Skin Filtering Technology.

I have been following with interest for more than one year the development of the original firewall modules which is an enhancement to the technology.

Approximately one month ago LessLoss introduced an improved version of these modules with an IEC C13/14 power plug and an Oyaide C079 Connector which was easier to introduce into one's system by attaching same to the power cable and the component.

I seized the opportunity to purchase two (2) of these modules. When the modules were introduced to the system the effects were immediately noticeable. They created a more quiet background from which music now emerged. The sound-stage also widened instruments appeared to move further apart and the vocal performer(s) if any, seemed to move forward. Even at low levels the full spectrum and impact were there. All music can now be played and enjoyed at intimate levels.

For experiment I unplugged the modules and the system reverted to its original status. Did I hear correctly? Was this really happening? I was convinced that it was so since when I reconnected the modules the improved effects returned. Vocal music was now very clear and silky without introducing the exaggerated "S" sound associated with high treble and what emanated from the speakers had an
extra inner coherence and dynamism.

Previously the music reproduced by the system was great but with the introduction of the modules I am now absorbed completely in performances. I realized that the system which I thought was a good system has now been elevated because of the introduction of the modules.

If these modules can improve the performance of LessLoss' power cables they will obviously improve the performance of any cable immensely. My advice to all music lovers is to consider the acquisition of these modules. My intention is to purchase modules for all my power cables.

Firewall Module

Installation of three FireWall modules into a headphones only system. The system consisted of a Mac Book Pro 15” retina (2014) feeding a Weiss Engineering D/A via a 1 meter Kimber 2436 USB cable, which, in turn fed my WOO AUDIO WES amplifier via1 meter balanced MIT interconnects. Jack Wu extensively modified the amplifier to an incredible performance level. The amplifier drove Stax SR 009 ear speakers.

All via DFPC Signatures, the first Firewall module was connected to a grounded wall outlet and then to a Furutech TP60 AC Power Distributor. Two Firewall modules were plugged-in to the TP60, one fed power to the D/A converter and the other fed power in to the amplifier.

It was a “bear” to get these 1.50” power cables into place. They haven’t been “dressed” yet as that will have to await the removal of the existing power cables.

1st Listen:

Well? What did I hear? How do I describe this? Essentially I heard a lot of nothingness! It wasn’t greater clarity, sublime tone, a driving beat, etc., or any other terms reviewers like to use. I became aware of the space between musicians. Their 3D placement of instruments was more obvious and snuck up on me without focusing. Further, the collapse of the venue’s reverb following loud or percussive passages was very prominent, almost physical! Truly. The precision of instrument placement was almost visible. For the 1st Listen, that was impressive.

First impression is very often the good one. YESTERDAY I received 5 new Firewall modules with oakwood case and Oyaide connector. I installed them one on preamp Vitus, two on stereo separated elements preamp Einstein, two on mono amps Soulution. So simple to install...

I let a little burning time and ? the only word I find is MAGIC. I spent many, many years and a lot of money to assemble a system with one goal "approach": the sound of live music. With the new Firewall immediately I perceived a superb bettering of the whole system on every quality I am looking for. But it's only the beginning of a new pleasurable listening experience. Many thanks to those who have realized such a GREAT product.

DFPC Series [Original]

Date Added: 10/17/2015 by Einar Magnussen
Looking on all the cables coming out from my power filter some months ago, I decided to start replacing my power cables before anything else. I had been to a two hours demo at the main Hi-Fi shop in Norway testing different power cables in to and out from Isotek power filters. The impact of different power cables on the sound was obvious. Despite the impact of a sound power cable, I left the shop with headache and a feeling that something was wrong with the sound and timbre when the sales man connected the most expensive Nordost power cables my budget could afford and a little more. The timbre was hard and lean. Instruments did not sound natural. I didn´t think more about it until I came across an incredible recording with Vytautas Sriubikis playing the Sarabande from Bach's Partita for Flute in the Baroque Church of St. Catherine on the Lessloss Web site a month later. The Flute Timbre took me straight into Lessloss sound philosophy and the dynamics of skin filtering.


Tonight I´m sitting here removing the last Nordost cable from my power filter. The last Nordost is sold. So I want to do a last test. What if if you have only one audio power cable connected to your source? After listening with only the Nordost Brahma which I thought was my best power cable, I replaced it with the Lessloss Original. I was a bit surprised. Only one Lessloss Original to my Dac gives better sound than the Nordost Brahma, even better than connecting the Lessloss Original to my Auralic Aries streamer and the Nordost Brahma to my Vega Dac. How can the cheapest Lessloss Power Cable do this magic alone? Instrument seperation is better, sound and soundstage is more focused and dissolved and the timbre is more organic.

So tonight I´m listening to the Bach Sarabande with my only Lessloss cable waiting for more to come. The headache is gone. Thanks to Louis Motek for making real stuff, not the type dreams are made on. And thanks for your incredible service, answering all my questions any time. I´m a happy customer.

All the best,
Einar Magnussen

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!!!
