Firewall ModuleDate Added: 12/25/2015 by Herbert P. Strenn
I was upgrading my hifi equipment for many years.These Firewall Modules are the best investment and the biggest improvement in sonic performance!

The new Firewall modules have been in-service now for a couple of weeks and I'd like to say how happy I am to have my best night time listening experiences extended almost 24/7. I'm contemplating buying some more as this has been my best cost benefit purchase by a wide margin.
I have a JPS Aluminata AC, a great neutral cord passing on the current to the CAT JL2 power amp as it should – yet never has it been able to give me reliable "late night type" listening sessions as the addition of 4 of the new generation Firewall modules has. I really do think it is the best way to describe the change. I have 3 systems all capable of some really good sound if fed ultra clean power. I am convinced now that most well designed and put together bits of kit will sound pretty damn fine if fed the ultimate in clean power.

Thanks for this incredible product. I tried the "plug and play" module between wall outlet and power distributor. I recognized the improvement right away with the first track played. Then I ran out of time and listened again a week later. (Power flowed through the module since the first connection.)
Wow, the difference was not subtle, it was huge! And all (!) parameters of the sound spectrum improved. Absolutely no downgrade to detect. Only pure wonderful musicality. It is amazing how you trickled down the $5000 Panzerholz item to this module everyone can afford. Any serious listener should have one... or two... or more... I'm absolutely sure that the Firewall module will receive several Product/Bargain of the Year awards. Amazing. Firewall ModuleDate Added: 12/18/2015 by Gerard from France
Presently I use 10 Firewall modules with Oyaide connectors throughout my system. First I connected my Vitus preamp and each of the monoblock amps and I listened. The result was a spectacular progress of dynamics and transparency. Second step, I put the same modules on the 2 power unit of my Einstein preamp, 1 on my Esoteric CD transport, 1 on Esoteric DAC, and 1 on Grimm clock. After some days of listening on various types of music, the RESULT: EXCEPTIONAL progress on every aspect which determines the quality of the system: dynamics, spaciality, transparency, and musicality. In a word, THE best WAY for getting your system to express its potential.

My DAC and amp are powered via a 12V car battery - clean energy!
Clean energy? What happens if I connect a firewall module? The sharpness of a violin gives way to a sweet tone. The bass changes from the trailer to a locomotive. My Rehdeko full range speakers talking to me: "Well, finally, 20 years, we have been waiting for!" I have two more modules for the speakers. What will they say if I connect this?

I have been blown away by the results. I have bought 3 modules: one for my streamer (Cambridge speedstream 2) and 2 for my speakers(B&W 683). I already had a LessLoss Power cable for my integrated amp so i did not add a module to the powerline.
After about 4 hours of brun- in, the sound stage was completely différent. The instrument separation is way more distinct. The overall image is crisper and more dynamic. The bass is deep and well defined, making me feel part of the stage. Midrange and highs are also substantially improved. I honestly did not expect that much Improvement. I still don't understand why it works but, a-t-il the end, what matters is the impact is has on my music. Great job LessLoss! Firewall ModuleDate Added: 12/11/2015 by Barry Howard
After many years of swapping components and cables I took the advice to first focus on room treatment and power conditioning. I now have a dedicated sound room with a power regenerator, conditioners plugged into it, jitterbugs, high definition links, audio grade fuses and a combination of world class power cords. I was convinced that I had lowered the noise floor of my system to a point where no improvement could be had but when I found out about the new firewall modules I couldn't resist and ordered 4.
I first installed them inside my pre and power amps, burned them in for an hour and then sat down and listened to very familiar tracks. My initial impression was that the music was spotlighted, not brighter but more evident. I have never experienced this before in this way. I've used silver cables that add treble detail but this effect was across the entire frequency spectrum. It was like studio recordings were live recordings. I believe that any grain or grit in the power source has been eliminated or at least minimized. I heard and felt much more ambient retrieval and the sound staging was better defined and different instruments were easily discernible. All sonic clues were more pronounced, i.e. if the music was recorded using the close or distant mike techniques it was really obvious. Bass had a bit more detail but it was the mid and upper frequencies that seemed more affected. The next day I installed modules in my DAC and phonostage and the pleasure was increased, not double improvement but noticeably more detail and a relaxation to the music. There was a time that I liked my music with lots of syrup on top but I now am a junky for detail without etch or grain. If there is a better or more cost effective product than the firewall module I don't know about it. What might these things be like daisy chained?!

I've finally had the opportunity to listen to my system with the new Firewall Modules. They were first burned-in for 48 hours on an Audio-Kharma Pro Cable Cooker. Two were installed to two separate Power Strips ( Acoustic-Revive RTP-4) for Digital and Analogue sources respectively, one directly to a Response-Audio RD100A tube CD player and another directly to a Response-Audio RA801A integrated tube amp via LessLoss DPFC Signature power cables.
After listening to selected tracks before installation, I was gobsmacked by the incremental improvement in the sound after the firewall modules were installed one at a time to each audio component. With the full complement of four modules, the sound was stunning, even from a modest system like mine and which I was already happy with. Not being proficient with all the technical jargon that pro audio reviewers use, I will try to describe the improvements experienced as best I can. The background was truly black, the soundstage became wider,deeper, with greater height and greater spatial clarity, bass was more precise and true with no boominess, highs and mids from "bright" recordings were "smoother" with no harshness. There was a heightened sense of "presence", like the performers were in the same room and yet all so "natural", even when listening at lower volumes. Most importantly, there was no listening fatigue after hours of listening. Bach, Beethoven et al, Eva Cassidy and Diana Krall never sounded better. As someone without a bottomless money-pit, it has been, IMHO and experience, a more sensible and economical way of achieving better sound by upgrading a decent system with components like these than buying an even more expensive system. Having experienced the significant improvements with both the DFPC power cords and now the Firewll Modules, I am looking forward to the soon-to-be-released LessLoss Echo's End DAC.

In the past I have purchased various tweaks/devices that claim to reduce EMI/RF and in so doing supposedly result in miraculous changes in one's system. Unfortunately I have not been so lucky in achieving what was being claimed. On the other hand, use of costly power conditioners from Audience and Shunyata have clearly improved my system. Thus, when I learned about the relatively inexpensive Firewall module, given my past experience with tweaks, I was doubtful it would make any difference whatsoever in my system. Nonetheless, I am always looking for devices that might further wring out a bit more improvement and enjoyment. If nothing else, it's always fun trying.
Initially I placed the Firewall Module on the power supply of my Mojo Audio modified Mac mini and after a day my first impression was that I had once again bought a tweak that I would soon be selling. Somewhat frustrated, I then decided to try it on another part of my digital setup, moving it to the Berkeley Audio Design Alpha USB converter as this has a relatively inexpensive power cord supplying it. Again, the first day, I was not impressed that I was hearing any difference but decided to leave it attached. I was very surprised three days later when I started to stream music and noticed that it not only sounded smoother but also more three dimensional with greater body and detail, well above and beyond what I was hearing previous to installing the Firewall. Realizing I was probably experiencing burn-in of the unit I thought I would move it back to the power supply to see what effect it had there but I thought the better of it. I didn't want to chance losing what I had achieved. Over the next several days I found that I was listening much more to digital music and for much longer periods of time. This was with only one Firewall Module in place. I now knew I needed to order more Firewall Modules to see if I could further improve on this effect by using it on other components in my system; that's how impressed I am with it. Highly recommended but definitely allow it to burn in for a few days before making any lasting impressions. Enjoy the music! Firewall ModuleDate Added: 12/10/2015
ALL the Audiophile "buzzwords" apply to this product !!
Blacker than the ACE of Spades noise floor !! Soundstage is wider, deeper & taller ! Easily identify each instrument & vocal in its place on the stage before you ! Natural & NON-fatiguing presentation where the listener can get lost for hours literally ! 
 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.
Excellent transaction with Lessloss on dynamic filtering power cord. Good communications & fast shipping. A+++++
Bought 3 pc's from Liudas in Jan/08. Outstanding product as advertised. Performance is everything and more than I expected. Kudos to Lessloss cable for a great product. Very highly recommended...A+++
Bought the Lessloss PC cable about a month ago; the quality and build are excellent. Compares very favorably with more expensive PCs. Highly recommended. Thanks!
A power cable that makes a huge difference; simply an excellent design. First-class sales and service - highest recommendation.
Cable #6 powering my Emm Dac6e which comprises part of my headphone system. Again, more resolution, detail, quietness from my Victor HP1000phones. Best single device in my system ever. Time to purchase more. I'm spreading the word re: this marvel!!
Liudas,your service is INCREDIBLE,no waiting 4-6weeks for cables and the ones I already have are doing more than I hoped A+A+,Thanks again,Don
Lightspeed delivery,very nice cable.I am kind of proud Liudas of such good cables from this part of Europe
Liudas is a honest and dependable seller, always answers my e-mail questions promptly. The LessLoss cable is a work of art, and sounds good too, cable is still burning in. I'm quite happy with my purchase.
Very smooth transaction, lovely cables. Thanks Liudas!
Amazing power cord! It beats my other much more expensive cables hands down - blacker background, natural, more details and dynamics. All my CDs open up and sound more musical. Brought two cables so far and will be buying more for sure. Liudas is a s
Cable #5 powering my Day Sequerra tuner results in being able to receive more stations!!! No more hiss, greater dynamics. Makes it sound like my ADA Tune Suite XM. This cable is the most remarkable product that has come my way in the past 20 + years
Kind and lightspeed fast service. The cable is a steal and outperforms other cables, costing much much more. Increasing every aspect of sound you can imagine. Absolutely outstanding!!! Thanks again Liudas.
Item arrived quickly and well packaged. Excellent communication. A great product from a great seller.
This is cable #4 in my system.Used powering my Ashley Xovermy MRS scares me out of the room!What power below 15Hz.No power cords that I have owned,many15X the $579.asking price have come close 2 this level of performance Looking forward 2 adding more
Cable #3 added to the PS of my Cello Palette. Well, no more static as I rotate the dials for the various frequencies. 1st cable to accomplish this! All power conditioners, including the Accuphase P1200 did not rectify the situation.Unbelievable!
Fast shipping and great sounding cables. Would not hesitate to deal with Liudas again.
This is my 2nd power cord from Lessloss. The first one was used to power my VRE-1, this one for the EMM CDSA SE. Again, a stunning result, w/quieter backgrounds, something that I thought I achieved w/the 1st cable. Next unit, the Xover.Unbelievable!
Excellent service and product, do not hesitate to try these cords. AAA+
Super fast shiping and a fantastic power cord. The very best I have ever used. Thank you Liudas!
You cant get a better seller in audiogon than Louis. For a cheap PC ( compared to many other manufacturers), he is responsive to your mails and even offer suggestion for cable configuration. Buy with confidence. First class seller with 1st class serv
Excellent seller...and truely excellent cable. The Dynamic Filtering Power Cable is just fantastic...musical...liquid...3D. Thanks!
Liudas has SUPERB DELIVERY,excellent communication. Cables are gorgeous.Can't wait till my amps come back,so I can reconnect.Can't say enough,check out all the POSITIVE FEEDBACK,Don Mitchell
The Lessloss offers WIDE dynamics.It's spooky quiet with an airy sound stage. Worth 10 times its list price.I am buying more!
Liudas is superb to deal with,4 day delivery to my door.wonderfully crafted cable. Excellent communication,and he's very patient with my questions,I'll be doing business with Liudas again(oops I already have)Thanks,Don
Very good sounding power cable,fast delivery-recommended.Thanks!
I own a number of well know and expensive Powercords that I use throughout my system. The Lessloss is clearly on par with the best for less. Used on the preamp of a system that was never bass shy, I felt like I had discovered another octave of music
Re: Purchase of Lessloss AC power cable. Immediately apparent something is special, it changes the envelope of the delivery of the music. The tripath solid state AR Amp sounds more flowing and used with my Tube SET, more bass from my 2 way speakers
Very good power cable at reasonable price, fast shipping, easy communication. Highly recommended, both product and seller.
Thanks Liudas. Very fast shippment, the whole transaction took 3 days. Excellent cable, the best I've owned. It's my second purchase from Liudas so I know from experience that it will be even better after burn in. Highly recommended.
Quick shipment and very good AC cord. I'll be back for more.
STELLA SERVICE. Felt like a valued customer. Cables are simply amazing. The sound stage is huge and sibilance free. Amazes me the way instruments and voices soar out of thin air. Thanks Luidas.
Outstanding service, excellent communication, and a fantastic product, one of the best power cables available for the $$$$. thanks again!
Quick delivery this time, My CD player never sounded so good. Thanks Luidas for another great cord to add to my system. A+++
I would like to thank Liudas for his excellent service. He is selling a fabulus product that helped me to solve the problem of high frequency harshness I experienced with my CD player.I will buy more cables to replace my Acrolink and Oyaide Tunami
I have now completed a full system (Digital/Power/Analog) integration using the LessLoss product. These power cables are a work of auditory art. Simply plug them in and be amazed! It's one product any sensible audio enthusiast should not miss out on.
I now have 4 of these in my system and every one of these on each component brought my system up to new levels. Nicely built as well. Highly recommended component!
Liudas is the gold standard in service. His cord in my system amounted to a hugh and positive upgrade. Thank you.
Outstanding service and the cable is as stated. The best I have heard so far over other regarded power cables. Highly recommend!!
Great on-going communications and terrific product.
I still find it hard to believe a power cord could be equal to or even greater than a serious interconnect upgrade, but it is! Thanks Liudas for the great product and perfect customer service.
The perfect seller in Audiogon: exceptional communication, easy transaction and fast and safe shipping. Recommended.
Perfect transaction.Great communication and very fast shipping. A+ Audiogon seller
Superfast shipping, good communication, doesn't get any better than this. Also, the cables are butifully made of high quality components. Thanks Walter.
Excellent transaction. A great power cable and company. Worth the wait.
A great experience overall, Liudas's enthusiasm for his product and the ongoing updates made this a very positive experience. The cord has made a significant difference in my system, most notably a much lower noise floor..
Trustworthy and very knowledgeable seller/designer/manufacturer. Kept in touch with updates and info. while cord was being manufactured and processed. It's all good - and all very high end.
Liudus is a great guy and the power cord is outstanding, I will glady buy from lessloss again, the cord took my system to another level
2nd entry; bought more cables. IMHO, better powercables than these are not available! Lessloss p/c's are MORE than a system upgrade. And 2 day delivery, from Lithuania?!! Amazing product!!!
Very nice sounding cable, beautiful build and a very reasonable price with fast international shipping. A+++
IMAGINE every listening session as your best listening session. Every recording played the best it can play. Your equipment performing always at optimum. Lessloss makes it happen! These cables are the best of the best!!!
In my years of audio and all the cords I tried Lessloss cords, made a difference you can hear for the better and it's not subtle. Good work Liudas! AAAA+
Excellent seller and Audiogoner, great communicator. Power cable is outstanding, excellent... Great soundstage, excellent definition, black background as promissed.
Liudas is great to deal with: excellent communication and service. The cables are very well made and well worth the money. Thanks!
Outstanding transaction and outstanding power cable.
Great transaction well worth the wait, this is by far the best powercord I have used in my system over the past 20 years, some cost as high as $3,000 and this power cord for $500.00 beat them all hands down and is a steal at its current asking price.
Top notch construction, performance to match, and a great transaction. Highly recommended because the cable does what is claimed, lowers noise while improving dynamics. Thanks!
If it was just always so simple !! Excellent, correct and accurate communication. Absolutely no loss at all even before listening to the cables. Highly recommended.
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!!!
Excellent service and communication. Fast shipping. Thanks, Liudas!
Excellent products! Delivery of the power cords and XLR digital interconnect cable,was received within 10days of shipping. Luidas kept me informed on the status of my order. Very good communication and feedback to my inquiries.
First-rate all the way! The cables are sensational, and the price is a steal. The 1-2 week delivery from Lithuania is well worth the wait. Liudas and Vilmantas at LessLoss are perfectionists pursuing their love for the art of music reproduction.
Before upgrading your gear, please try the Lessloss Blackbody. It works wonders with my equipment and adds a realism, a new quality to the sound that will leave you speechless. Absolutely wonderful piece of gear.
