Do better ingredients make a better Ground Wire?

I'm glad the safety issues were mentioned.

I took my Classe amp S-700 out of my system. And put my modded dual-mono Adcom 555-MK11 in it's place with my DIY Ground controls on the amp negative speaker post just like I did with the Classe S-700. There is an even greater improvement with the Adcom than with the Classe. I have bragged about this Adcom in other posts, but it never sounded better than the Classe, until now! With the DIY Ground Controls the Adcom is visceral, open, wider sound stage, bass now has not just very deep bass, but low bass, mid bass, upper bass. The mid range has more presence to the voices, they just sound live and real. This is laughable how much this already overachieving amp has been improved by this simple tweak.

Probably not such a simple tweak really. Just does a number of things with the least amount of stuff. You really should buy one of the $150 sets and test it out against your DIY item, just to make sure you have all of the benefit. Not dissing your efforts at all, you have just left out aa couple of descriptions of the changes wrought by the full package. You can always return them, claiming lack of change....

I do find it very interesting to discover just how good the equipment we have really is, once the back half of the wave form is properly supported. Neat to know that even Red Book audio, out of a cheap Sony CD / SACD player, can sound wonderful and that a Nikko Beta I SS preamp from the 80's is an incredibly delicate and nuanced preamp, not the hissy, hashy high end, thing that most people find with them. You really do need to explore the RCA Ground Control devices.

Hi, Bud. I used the $150.00 dollar set of Audio Prism Ground Control as my reference before I started this post. So I have directly compared them to my DIY version. And in direct head to head match ups with the DIY versions I made, the Audio Prism Ground Controls were a behind the two versions I made(solid Silver - Silver Palladium mix) I would love to compare my DIY to the Audio Prism Reference Ground Control. But they are priced much higher. I do have my eye on the RCA ground control for equipment(preamp). Thanks for the suggestion.

Sounds like what we found the first time we used the XShadow 100% silver spades on speakers and amp posts, quite a bit better inner detail and nuance, even though it was still just from the back side of the signals. I was quite skeptical that solid silver would be better than copper / gold plated spades, but my doubts disappeared rather quickly. Careful listening showed that leading edges of all sounds were just as they had been without any Ground Control, and that the silver made more"sense" out of the rest of the signal than did the gold platted GC's. And yet, the gold platted units only sounded murky in comparison with the the solid silver spaded units. In comparison to none, it was again back to the "not ever leaving my system" mind set.

The RCA's reveal a greater difference between silver and gold plate units. The silver RCA's, on the preamp, caused me to remove the internal GC's from the Sony player and plug in two gold plated RCA's in place of them. Silver RCA's on the Sony was just a bit much, very resolving, without actually curing the OPAMP ground side starvation. The gold units seemed best there.

Still learning about these little jewels.
