BlackGround Power Base

Date Added: 04/18/2024 by Zoltan
I ordered this "box" with trepidation. Over the years, I have spent a lot of time and energy trying to get the right power cables to my devices. After reading the reviews I had rather high expectations and was afraid of being disappointed.

But the very first second blew away all my doubts. I didn't have to look for the difference as it slaps me in the my face immediately.
However, I also read that it is worth the wait, because the effect would mature over time.

I've been using it for over a week now and I think it was one of the best investments I made. Not only one tiny detail of the sound picture has improved.
Everything has become much more precise, tighter, but at the same time the music has not lost its sensuality, it has also brought out its emotion and passion.
The presence of a stage has become more noticeable and deeper. The experience is more immersive than ever.
Yesterday I sat listening to music for hours with a grin on my face, without getting tired.
I think I have arrived. I've wanted to come here for years.

Congratulations and thank you.

Firewall Module

Date Added: 06/23/2024 by Mac Finney, Baltimore, Maryland USA
Stellar Firewalls for Loudspeakers are otherworldly!

I won’t apologize for sounding like a LessLoss fanboy! The Power Base, Speaker Base, Stellar Power Cables, 640x Entropic Power Modules, Standard Firewalls for Loudspeakers and Entropic Speaker Cable & jumpers I have in my setup combine synergistically to produce the most heavenly sound!

However, a recent upgrade from Standard Firewalls to the brand new Stellar edition have transformed my system from dreamy to otherworldly! Speakers vanish into blackness. Poof! Walls disappear. Poof! Music floats free & easy. Soundstage wide, tall & deep. More space around musicians & instruments. Their locations well defined. I’m able to see & hear behind each note played. Very holographic!

It’s as if I traded my very nice seats as an observer to become an active participant on stage in the making of music. The emotional attachment is intoxicating!

The LessLoss trade up program is both generous & easy. 2 stereo pairs of Standard Firewalls, 4 individual Firewalls per speaker, became Stellars configured in series, 2 red & 2 black per speaker. After 100hrs of run in time, this upgrade, combined with the other excellent LessLoss products in my system, represents a dramatic leap forward. I’ve never felt closer to the music than I do now!

Bravo Louis & LessLoss!

BlackGround voltage-ground interface; Blackbody

Date Added: 06/27/2024 by Drew from Portland, Oregon
This review is for both the BlackGround and Blackbody v2. I'm not going to re-state what has already been said. What I will say, is that I have recently become addicted to LessLoss products. After reading forums discussing what these devices have done for others systems, I pulled the trigger and bought one Blackbody. I hooked it up as soon as I pulled it out of its UPS package. It provided a noticeable upgrade in SQ. Since then I've added one more BB and two Blackgrounds. I just received my second BG yesterday. The improvements in SQ have me glued to my seat and shaking my head. The music sounds so good with anything I play. I stream Qobuz through Roon and it's like every track has been remastered to some super high resolution method yet unknown to mankind. My system consists of ethernet coming off my Orbi router with a Furutech cable to a FMC converter to optical, then Melco ethernet cable to a Sonnet Hermes streamer to a Sonnet Pasithia DAC via Melco cable. From there I run Jena Labs Pathfinder cables to a Whammerdyne hybrid amp driving Lii Audio Platinum 10's with a pair of REL G2 subs. I feed everything with DIY Furutech PC's using their DSP 4.1 cable and NCF connectors. I use 10ga Duelund wire. Prior to having these 4 LL there were certain songs I could play at higher volumes because they are recorded so well they simply deserve it. I tend to pick out an artist and hit play on the artist Radio Station so I can enjoy some variety. When doing this, most songs I can leave the volume up, and certain songs I have to tun it down, because something sticks out with the mastering that just doesn't sound right. I know my system is pretty good, but definitely not the last word in being resolved. Fast forward to today, I have have been streaming different genres, time periods, and formats i.e. FLAC, for several hours and I have not needed to turn the volume down. Everything played sounds great. Along with my system explained above, I have done room treatments, grounding blocks, updated my power supplies, done carbon stickers, among many other tweaks, all have had some level of positive impact on SQ, but nothing comes close to what I am experiencing. These four LL devises have been a revelation. I just placed an order for a set of Firewall for speakers, and I will continue down this path. Thank you team LessLoss for your hard work and bringing us products that truly make a difference.

Firewall Module

Date Added: 06/28/2024 by Joerg Meinhardt, Germany
Again a wonderful upgrade, this time the Firewall for Loudspeakers Stellar version.

Since 2019, I have the first version of the Firewalls for Loudspeakers with some upgrades to daisy chain on other loudspeakers with separated crossovers. Feel free to check the reviews from that time. I was very excited and up to just 3 weeks ago very happy with them.

Since 3 weeks now, I have the Stellar version in my system and am very happy and astonished of this improvement. Just switched back to to the “old” one, to check whether I was not remembering falsely. And yes, it was correct:

Just as always, everything is better, more natural and realistic, like:
- Stage wider in all directions
- Instruments and voices are better separated
- Background more silent then ever
- Attacks improved
- Bass have more structure
- Loudspeakers disappear … probably best what can be
- Better decryption of lyrics
…

Today, the “old” non Stellar are going back to LessLoss. Such a great way to upgrade with a good price and no worries about selling the old ones.

Thanks again, Louis and team, and gratulations for this new product. I love it!!

BlackGround Speaker Base

Date Added: 07/05/2024 by Mac Finney, USA
As I anxiously await a pair of Blackbodies & pair of DIY Blackgrounds with necessary cabling, I continue to be surprised by the improvements all the other LessLoss products have made. The following list reflects which LL product has had the largest positive impact to my listening experience & not the order I purchased them.

1 - 10x Blackground Power Base
2- Stellar Entropic Firewalls for Loudspeakers
3 - 8x Dual Channel Blackground Speaker Base
4 - Entropic Speaker cables + Entropic Jumpers
5 - Stellar Entropic Power Cables
6 - 640x Entropic Power Modules

Blackbody

Date Added: 08/04/2024 by Mac Finney
Initial impressions of the Blackbodies with DIY Blackgrounds reminds me of being at my favorite place to chill in the beautiful Maryland countryside which happens to be the gorgeous horse farm where I live. Imagine that it's a partly cloudy day, but as soon as the Sun emerges from behind a cloud, EVERYTHING POPS! You now feel more present and emotionally connected to your environment as a flood of color & detail washes over you. And that's a very good thing!

C-MARC Stellar Power Cable

Date Added: 09/06/2024 by Jean-Michel ANQUETIL
Stellar power cord: Call me » Impressed «

I have done a couple of listening sessions with this new power cord (replacing a C-MARC Classic Entropic) on the power supply feeding my Totaldac D1 DAC and Reclocker. The Stellar has run only 6 hours and the result are already very good.

This afternoon I went back to the Entropic to check… and ensure my ears are not lying to me. The progress bringing in musicality by the Stellar is quite significant; I did not expect that much more improvement.

What I do hear is more body in the music, a nicer and more detailed top end, a more articulate bottom, and overall a better top to bottom balance. All that gives more life to the music!

You are right: attention to the power side of our equipment is absolutely critical.

C-MARC bulk wire and cable

Date Added: 09/09/2024 by Gilles Bordet, Cohérence Audio, Switzerland
I'd like to offer you a little feedback on your C-MARC™ cables.

We have used your cables in many applications and configurations. The results have always been excellent.

LessLoss cables are pleasant to work with, and the cotton insulation doesn't melt, unlike plastic. This has enabled us to work at higher temperatures with high silver content alloyed solder.

These cables are very pleasant to listen to. The noise reduction is remarkable. Definition is also excellent. The entire frequency range is faithfully reproduced.
These cables are really excellent products.

We will be integrating your cables into our new products.


Best regards,

C-MARC Stellar Power Cable; BlackGround 6x/10x Power Base

Date Added: 10/07/2024 by Maurizio
During the last few years, I have been using a LessLoss distributor with all connections made with C-MARC “Entropic Process” cables.

Both signal and loudspeaker cables in my stereo system are also with C-MARC “Entropic Process”. I have been greatly enjoying listening to music with such a set-up.

I recently purchased a BlackGround 10x Power Base, and upgraded the connection to the wall socket of the distributor with a C-MARC Stellar power cable. I also used a Stellar power cable to connect the BlackGround Power Base to the distributor.

In few days, the reproduction of sound has acquired an astonishing transparency that personally I had never experienced before. It is what I imagined being the exclusivity of stereo systems much more expensive than mine.

It is now much easier to follow the playing of several instruments and to appreciate sound that before appeared as being only in the background and behind a veil. I can now detect much more easily the differences between several versions of the album that previously appeared just as nuances.

For instance, last year I borrowed the UHQR vinyl of “Kind of Blue” and after listening to it, I concluded that it sounded just “a bit” better, but it was not worth the price. With the new set-up, I listened to that vinyl again and, thanks to the so much improved transparency, I realized that it sounds so good and I decided to keep the UHQR vinyl.

Encouraged by the successful experience with Stellar cables, I decided to finally replace the original quality power cords of the two PSUs of my DAC, also with 2 Stellar cables.

This last investment was also worthwhile. The sound of the DAC is now by far more comparable to that of an analogue source:

I now discover details that tell more about the very music and all this is effortless, no more need to “focus” especially on what I was listening to
