Maestro vs. Furutech GTX-D Gold AC Outlets

I agree with Lacee.

I have,in-house, right this very minute, Synergistic Research Tesla Plex, Tesla Plex SE, Oyaide R1, PS Audio Power Port and Power Port Premier, FIM and FIM Gold, Maestro and the Furutech GTX-D (Gold, although I wanted Rhodium).

The Furutech is so far ahead of ANY of the others, there can be no disputing the differences. The grain is akin to that of the Hurricane amps, which is to say: Zero. The dynamic range soft to loud)and contrast (tiny inflections) surpasses the Synergistic - which I bought only 6 weeks ago. The Furutech has 16 hours on it so far.
The first 10 minutes, I couldn't tell. But 3 hours later, I could, and in a BIG way. Got up today and listened to it 20 minutes ago, with the amps not even warmed up, as I wanted to hear what it sounded like from a cold start, and whether or not the system being warmed up would hide what it sounded like last night with the system warmed up and 3 hours on it.
It was so obviously better, even cold, I just blinked and muttered, "Wow."
I've had audiophile ac receptacles since 2003, so I'm not new to this, just as I had tube traps back in 1988, dedicated lines in 1989. I've done EVERYthing that could be done to make it sound better (including something most people scoff at: keeping the speaker cable off the carpet, which I demonstrated made a difference back in 1995, at the publisher of Fi Magazine's home, with Dick Bel, Tom Miiler, Sally Reynold (TAS' former Executive Editor) and a few other VIPS). It works, and if you're not doing it - or you don't hear it, I don't know what's wrong with your ears. Every speaker cable I've had, which includes: Nordost Valhalla, Transparent Audio Ultra (from 1993), then the Transparent Reference, MIT, Shunyata Andromeda (Constellation Series)and a few more. How someone cannot hear the difference with interconnects and speaker cable off the carpet is beyond me. Enid Lumley knew what she was talking about. (People just lift it off the carpet without understanding their cable will take time to settle. Wait 4 hours and THEN listen to it.)
Back to the subject at hand: if I can determine a way to put the Furutech in my PS Audio Power Plant, it's going in there, too!
Unquestionably, THE BEST. BAR NONE.

Here's a bit of an update.
I have now placed the Furutech at the end of an ordinary line,not a dedicated one, and the wiring is 14 guage romex standard house wire,into a standard wall fixture.

What I can now add is that even if you can't run a dedicated line from a 20 amp breaker and use 10 guage wire,you can still improve your sound if you use the Furutech GTX receptacle.

just received my Rhodium receptacle. It is unquestionably "crisper"-sounding than the gold, by which I mean transients 'pop' more 0-to-60 than the gold and the overall sound is less 'warm,' but only slightly. I have this on the front end, where I previously had the Gold, and I prefer it. Given that I had a CJ Classic SE as well as an ET3 as the preamps, it's pretty obvious that the Rhodium suits me better. I'm getting another Rhodium for the amp outlet (dedicated). I had considered keeping the gold, but I don't need warmth in my system, unless it comes from the recording. I prefer hearing the ambience of the acoustic environment, as well as the timbre of instruments, along with whatever fullness/body I hear in them in real life. So, back goes the Gold for another rhodium.

I've just ordered two Maestro outlets. These will replace two Porter Ports, they replaced two FIM 20 amp outlets. It's been quite a while since I put in the PP outlets, but I can say the sonic benefit was substantial. One major concern I've had with the PP outlets is that they only seem to grip the last 1/4" of the prongs of my power cords. This, to me is unacceptable. I've not read any other end user remark on this and I find it hard to accept that I bought two inferior outlets. I have two separate dedicated lines in my room, one for the front end electronics and the other for the amp, subs. These two lines feed my Shunyata Hydras, a four for the amp/subs, a 6 for the front end equipment. If there is any interest in my findings, I'll post them later.

I have the GTX-D rhodium and I agree with Gbmcleod:

It's utterly grain free. Also quite lively sounding with jaw dropping detail retrieval, though it doesn't have the bloom of the Maestro.
