Synergistic Research Tesla Plex SE ac receptacle

Thanks Tonyptony.
I may eventually try a Maestro, but I'm going with a Furutech GTX-D eventually.
And I trust your experience, but I do need to point out that Neil Gader has also had these (although with a Powercell 10SE) and was quite impressed.
I do not doubt at all that the Maestro may be superior, just that it would be strange that the Tesla had an artificial quality in the upper mids/lower treble. How did it manifest - meaning what sounded "wrong"

I have auditioned Ps Audio Premier, Oyaide R-1, and the Synergistic Research Tesla Plex. Each has their own sonic imprint. The SR is the most open across the entire frequency spectrum. The Oyaide R-1 is darker,but not muffled. The PS Audio more high frequency emphasis. The audio circuit has 5 receptacles. Currently my system sounds the best with 4 Synergistic receptacles plus 1 Oyaide receptacle. This circuit was further improved when I had the circuit breaker "Quantum Tunneled" by Synergistic Research.

Well, I'm going by memory at this point, but as I recall there was something in the upper mids / lower treble that just - over long listening sessions - seemed not as natural in my system as the overall feeling I got with the Maestro. The difference was minor in the grand scheme of things, but I just felt over hours of listening that I got a more realistic, natural sound and presentation top to bottom with the Maestro. I suspect I could have changed some ICs in my system and the choice could have easily been the Tesla. I didn't dislike it by any means. The Maestro just helped my system sound more like what I hear when I go to classical and jazz performances. Sorry I can't recollect it at this point with the standard audio jargon.

If it helps, I liked the Tesla SE better than the Oyaide R1.

I think many people may get better results with Furutech GTX-D rhodium receptacles.

+1 with Sabai, Agreed, The Furutech GTX-D Rhodium!
