The 640X is amazing. It is on my transport the place where your filters have had the least impact in the past compared to power amp and powered woofers. It is MUCH more transparent with a much lower noise floor and increased space and depth. Increased tonality as well. These changes pale in comparison to the sense of musical expression it allows-even with distortion and poor tone ie Woodstock Live it feels like the performers are in front of you blasting away. The micro-dynamics become macro-dynamics as the singer gains both nuance and dynamic power. Artistic intent to the max! Cannot wait to hear these on my power components.

Firewall for Speakers replaced "black box" speaker filters costing twice as much and, after break-in, made my vintage Sound Lab speakers BLOSSOM to new heights and a never before attained enjoyment of my system.

Just added the speaker firewall in my system last week. For the first 24 hours sounded much quieter in noise than before, but at the same time sounded slightly muted and rolled off.

However after 2 days of on and off playing, the system simply blossomed. The soundstage is wider than it has ever been. My system was faster and also had much more noticeable detail then before. The improvement in my opinion is better than a component upgrade.

I am a purist audiophile. Was very sceptical about adding extra pieces of wire into the system. But after hearing the speaker firewall in my system, i cant live without them.

[LessLoss power distributor with onboard Firewall technology and C-MARC Entropic Process Hookup wire throughout]

I got the new conditioner/distributor today, 6 outlets.
Replaced my conditioner, one that took a long time to find which was in my
opinion the best.

I took a risk, but a calculated one, first, every product from LessLoss that
I tried was WOOW, second, a friend of mine has a LessLoss conditioner.

This conditioner is outstanding, a dream of every audiophile, clean power
with a passive conditioner, without all the disadvantages of an active conditioner.

Well done, again!

The Entropic Process is quite something, as there has been no drop whatsoever in quality whereas my power and speaker cables (Heimdall 2) had been in the system for well over 18 months, possibly two years... And the sound is getting lusher by the day! Quite an achievement from you and your team, please share my congratulations to all.

C-MARC RCA unbalanced signal cable, stereo pair

Date Added: 02/22/2021 by Tobias, Germany
After some extensive listening time with the C-MARC RCA cable, I thought I‘d give you some feedback on what I’m hearing.

I’m using the cable to connect a Chord electronics DAC (Hugo TT2/M-Scaler) to the (extremely resolving) RAAL Sr1a headphones driven by the matching amplifier from RAAL (HSA-1b), listening mostly to acoustic music, particularly opera, Lied, piano and strings, Jazz and singer-songwriters of all kinds. I own a number of pricey high-end cables, which I use for comparisons.

After a week or so, the sound with the C-MARC cable started opening up quite spectacularly. First off, it appeared somewhat muddled to my ears, darker than I‘m used to, and I assumed that what I was hearing must be a tonal change to the unnatural. I heard „more bass“, but also „less highs“. However, after another week of extensive listening, and after comparisons with other cables (some considerably more expensive), I came to the opposite conclusion: I have never heard such natural sound through my personal audio. Rather than making the sound „darker“, the cable seems to take away artificial sounds that other cables sometimes add, leaving more of the actual music. Instead, there’s slightly more space around the instruments and voices. In my ears, this leads to clarity and precision without any hint of sharpness, while also sounding „fuller“ compared to some of the other cables (e.g. a silver cable of mine that is also very clear but seems to slightly diminish the natural reverberation of acoustic instruments).

This effect became particularly evident to me with solo strings instruments, which to me have been borderline unlistenable on highly resolving equipment. Now I can actually enjoy solo cello or violin recordings without any fatiguing effects; sometimes, with good recordings, it even feels like actually being at the recording or concert venue. Looking back at my first impressions, it seems that I used to mistake sharpness for precision or clarity, effectively expecting a different sound from my Hifi than from live concerts (burn-in might have played a role, too; and perhaps the fit with my rig is particularly great, I haven‘t tried it in other combinations). In any case, it feels good to go back to natural :-;

In short, the cable delivered on my expectations and more. Based on this experience, I‘m now thinking about experimenting with your other products, too.

Bindbreaker Vibration Control Equipment Foot

Date Added: 02/19/2021 by René Copenhagen, Denmark

I am totally in awe!

A week and a half ago two sets of three Bindbreakers arrived by express UPS Service. My High-end buddy and I had long enjoyed the astonishing benefits of LessLoss products, C-MARC Firewalls, Entropic Power Cords and digital interconnects were in both our setups, supplemented in mine, by a specially build 10 outlet Entropic distributor/conditioner, Entropic loudspeaker Firewalls and Entropic Loudspeaker cables for my satellites and subwoofers.We had frequently discussed what might the Bindbreakers be able to bring to our already very well seasoned setups being able to play any kind of musical style with delicacy and heft.

We both agreed LessLoss has never oversold ANY product to our knowledge, then again, we both had experience with feet under equipment, Black Diamond Racing Cones and others, and yes, they make a difference but ....

We decided to buy two sets together, with the possibility of trying both but in the end saving some money by settling for one set each, were the end effect there, but miniscule.

Well, both sets arrived at my place and I decided to begin with one set of three under my newly aquired dCS Network Bridge, an astonishing streamer, best I have ever heard. After an hour of burn in - yes, to my surprise BBs need burn in time - I thought it should be illegal to sell the dCS without Bindbreakers, such was the improvement on all parameters.

BBs have puzzled me. They are not the kind of "in your face" enhancements, yet, I dare to say an enhancement I can no longer absolutely not live without. So what do they do?

Above all else they make your setup ridiculously fast in a splendid way. Reaction - acceleration and braking time is shortened in a way that opens up the sensation of space, scale, depth, micro- and macro dynamics, slam and tip-toe expressions by musicians plus tone color to die for, I mean the setup literally sings it's heart out as the best singers magically can.

That is what I cannot live without anymore. A week and a half ago I hadn't the slightest notion of that, only an undefined longing for.... Know that feeling?

Let me fill you in, if you are still with me.

At the end of the day I placed the second set under my LessLoss passive conditioner/distributor. Sho' 'nuff, more of the same and I stayed in sonic Heaven not being able to leave Radio Paradise as the next song kept opening up so intriguing that I just had to hear that one too. Mind you, Paradise casts compressed AAC, good quality, but compressed. I just couldn't care, just had to listen.

After three wonderful days of almost 24/7 Radio Paradise my buddy wanted to try out the feet in his setup. I removed them, took them to his home, and, listening to his heavily improved setup I had not yet heard after the change, without installing them, was able to precisely predict to him what nasties they would remove. I was right and he was stunned. Placing just one set under his heavily modified Oppo streamer/DAC repeated what had happened with my sound. A few hours later I left him with a smile that almost ran twice around his face only to return to my own setup that had now turned completely dull. For the next week I could hardly bother to listen to music, not even the very best recordings and certainly not Radio Paradise which I started a couple of times a day but left after one or two songs.

My high-end companion of course bought the second set from me after four days not wanting to go back to HIS now dull sound and I could finally order not two, but four sets for myself. I simply could not help it though my poor purse screamed in agony.

Yesterday my new friend, the UPS truck driver, arrived with two bags containing the twelve BBs and it felt as the morning sun came in after a long winter storm. Burn in time repeated itself, but after an hour I had most of my wonderful sound back by placing three BBs under my streamer again, and, as in a fairy tale, Radio Paradise seemed to broadcast the same specially enhanced quality as a week before. Half a day later I lowered my all digital Steinway&Sons A2 four channel power amp/DAC/room control unit on the second set of BBs and I was equally stunned!

Almost all the deep lows disappeared, sound got two dimensional and irritating and dynamics were gone. I was honestly chocked. I had purposely let the music play during the placement of the unit on the feet, not cutting signal at all to omit the power on/off sound change always there. I'm so glad I had experienced the burn in time already, so I stayed (almost) calm and kept listening. Lesson for y'all, don't judge BBs too early!!!

50 minutes later the tone color was nice again, scale and space had improved, and I could hear what the bass player did to his instrument, not only bass notes. After two hours the sound was better than it has ever been proving that enhancing signal sources with BBs take priority over conditioner/distributor - just like Louis had already stated.

I am so lucky to still have two sets waiting to be unpacked, but that is for a follow up, folks. All I can say, is, Bindbreakers may not be in your face improvements but once you have learned what they do, you cannot live without them.

To be continued .........

[C-MARC Firewall 64X]

Attached is a picture of my granddaughter, Rosalyn. Felix, my son, sent it to me today with the caption: “I think we have a LessLoss fan!”.

He snapped the picture as she heard her children’s songs for the first time with the C-MARC Firewall 64x replacing the regular plug-and-play Firewall 64x model. Her spontaneous reaction, without having been told anything had changed, was to singlehandedly take the stool to the speaker shouting: “Dad, what am I hearing?” She turned five in December.

My son and her mother sat chatting on the couch and all of a sudden they heard her scrambling the stool in front of the speaker shouting the quoted in excitement. She stayed there for several songs to hear the “new” old songs she’s known for years.

C-MARC Classic Power Cable

Date Added: 01/31/2021 
I thought I had a very musical system -whatever this means- with special attention to cabling and power in general. Just two power cables were not highest grade in comparison to the rest. Anyway, I could listen for hours and hours with great emotion, pleasure and without any fatigue.

Then I decided to change the two mentioned power cables by switching for the first time to Lessloss products and chose the C-Mark ones without Entropic Process. The result: After one week of burning-in I HAD to listen for hours and hours.

Then I added the Firewall for Loudspeakers. I have not been able to stop listening yet...

I’m still wondering what the Entropic Process could cause. I’m more than tempted.

Thank you very much, Louis&Team. What a pleasure!

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!!!
