C-MARC Grounding Cable

Date Added: 05/09/2026 by Serhiy
First of all, I would like to Thank You for the great products you have designed, namely the C-MARC cables. They have truly made my system, I couldn't and still can't believe how a cable can make such a HUGE difference on the grounding path, not even the direct signal path!

The C-MARC cables are legit!

I would like to share with you my story.

So here's my story, since I've been working on my electricity for a while now, my latest journey was the Grounding stuff that a lot of you might think is Snake Oil, but read on.
After my Power Conditioner (Vinshine Tai Hang), I got myself a GroundMaster City Ultra (Henceforth: GMCU) as the grounding box, since I've had experience with Puritan's PSM156 box, The PSM156 is a great Power Conditioner as well, I didn't really "upgrade" it to the Tai Hang, but there was some buzz with the Tai Hang and I wanted to hear it for myself and I've had the perfect opportunity to exchange the PSM156 for a dedicated power line. Anyway, the story is not about the Power Conditioners but the Grounding stuff.

I connected at first my GMCU to Tai Hang and immediately heard a drop of noise floor and better dynamics and everything. Then after some more upgrades (Power cables) and some burn in things were looking and sounding good.

Then I decided since GMCU is such a great device to add to it the RouteMaster (Also from Puritan) so I can add some more grounding work to the rest of the chain and connected it to May and Astraeus, while there was even more drop in the noise floor, dynamics suddenly DISAPPEARED. with that I tried to play around and also change my tube, I've had the Ei Yugoslavia in and change it to the Tesla PCC88, that actually brought back a bit of the dynamics but still not enough, later within 4 days I've had it all back things locked in, sound became sweeter, more open and with dynamics. Then the Puritan/Furutech dealer also recommended to change the stock Puritan grounding cables to LessLoss small cable with Furutech/AECO connectors, after some thought and a bit of research I decided to go for it, wasn't too expensive (Even though he warned me it would be expensive), anyway, today I got my cables though there was a mistake in the connectors but 2 cables out of 4 I managed to connect just fine. Connected them and expected a drop of sound quality or at least it starting from the same point I left, what happened was that it actually stayed the same and even became better from first impressions.

A few tracks later, I cried, I cried hard, while listening to Immanis, From content on Youtube, I finally heard great sound, the first wow moment was from the bass coming from Geoff Castellucci - The Sound of Silence track, it was so impactful and authoritative and full bodied... then suddenly a few fairly flat tracks, then another great track "O Death" by The Wellerman that had great dynamics and BODY to voices. Then things started rolling from there non-stop, with all the details, sound was coming out of different places with mostly pinpoint accuracy, I could hear sounds far out in the corners echoing out of the black background, voices were coming from black background going around the stage like completely 3D, that was all from Youtube.
I cried so hard I had to stop the music try to understand.

Music was finally reaching to me emotionally.

TLDR: Immanis is amazing, but even if you have the best DAC or Amp and you don't feel like it's doing it for you, you must work on your Electricity and (Signal) Grounding. It's not snake oil, not even close. It will make you cry.

Best Regards,
Serhiy
