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.    Firewall ModuleDate Added: 11/17/2018 by Neill L.

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. Firewall ModuleDate Added: 08/22/2018 by rh
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! Firewall ModuleDate Added: 08/08/2018 by mdc
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. Firewall ModuleDate Added: 08/08/2018 by Jörg Stanislawski
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! Firewall ModuleDate Added: 07/31/2018 by Michael R.
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...
 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.
