Furutech GTX-D Rhodium NCF Outlet


Hi

I have been using a strip with Cary tube preamp and digital sources on a Furutech GTX-D Gold outlet and Pass power amp to a Maestro on the wall for a while now.

The combination seems decent but lately with some bass heavy recordings I have found the bass thick and boomy on extreme low bass notes. The mids and highs are fine and I tend to be sensitive to bright treble.

I took the preamp out and put it to the Maestro on the wall and this ameliorated the bass somewhat. Everything became fuller sounding but as a result, there was less low bass reverb (sounds contradictory?)

I suspect it is the GTX-D Gold. I am guessing if I replaced that with a GTX-D Rhodium NCF, it will tighten up the bass and hopefully eliminate the excessive low bass reverb. But in doing so, will the highs become too forward, hard or bright as Rhodium tends to be vs Gold?

Any experienced feedback from users who have tried the Maestro, GTX-D Gold and GTX-D Rhodium NCF is much appreciated.

Thanks

I recently purchased ten Furutech GTX-D Gold, and seven Furutech GTX-D NCF Rhodium duplex, over a period of two months to install  in my system (wall, extensions to system with six duplex on floor in boxes, plus all duplex in two power conditioners) (I actually have removed two gold and added two Rhodium as time went on)
I fully agree the Furutech Gold are warmer and slightly more 'congested' sound than the Rhodium. And that the Rhodium are a PITA during break in, which is LONG.. The Rhodium bring a tilt to the treble which is somewhat annoying during break in, and it comes and goes... Think all is well and the next day the tilt is back.(Some of the exaggerated experience I had may be due to adding in more of them as time went on, plus adding in a total of six Furutech AC plugs with Rhodium.. all over a two month long period. So My experience may be  more extreme than others with the Furutech Rhodium products.  But the Rhdium are totally worth it! I like the Rhdium for amp, from wall, and preamps. The Gold seem better for most sources.    
As for what positive they have done? CLARITY. My Magnepan 20.7 speakers sound for say, Rock vocals is as clear as listening via good hadphones now. Used to be I struggled to understand too many of the vocals. Now, clear and natural.  better attack, better leading edges of notes.....         
One other phenomenon I noticed is if I stick powercords with a brass plug, even one PC back into the system (think Wattgate basic plugs) I can hear a distortion in the sound, particularly in he upper midrange, a background with a sort of velvety haze behind the notes. As soon as I remove the brass plugged PC, the haze is gone.  (Wen I replaces the Wattgate with Furutech Rhodium, keeping the DH Labs wire, the haze went away)         
This goes to (all in theory all in my head to 'explain' the phenomenon.. True or not??? And it may only be the Wattgate plugs, and not 'all brass'?) Anyway, my 'theory' is since the Furutech have NO BRASS or bronze, (Furutech uses pure copper parts inside the Duplex, using a clever spring arrangement around the blades to maintain tension) SO with only pure copper, and no brass parts, a distortion hitherto unknown to me, has been exposed.So I am convinced (just on this one set of experiences) brass AC parts suck. And the only reason folks do not know, is they have never been without such parts! Once you get rid of the brass AC bits.. You will also know it is true ... Brass sucks.(I don't have experience with bronze AC parts.. so unsure about those.So right off I would say all you with $$$ duplex still made with brass.. sorry for your loss. hah hah hah... (Rub in it will you? and suddenly all those big buck duplex made from basic Duplex stock owners and maker are up in arms) Whoa put out this fire!...

Since you are in Malasia you could try a Synergistic Research Blue outlet from their Hong Kong dealer. Lowther China. E- mail: creevyyu @gmail.com.I have not tried or read any feedback with the Cardas outlet. I have tried the SR Blue outlet and the Furutech GTX-R outlets and while both are excellent I do prefer the SR Blue.

OK so I got the GTX D Rhodium NCF’s.

I have about 5 hours on them now. I have the Cary tube preamp and digital sources on a strip to the outlet. I have the Pass Labs power amp on the Maestro.

There is greater clarity, air and instrumental separation. Image outlines are also more distinct, but with less bloom and fullness - I guess this would constitute a minor negative. The bass has tightened up and there is more micro detail all round.

More on the downside, the treble has become "silvery" with a bit of hardness and brightness. There is more extension but the sound doesn’t seem like it has opened up yet and still sounds etched and shut in.

I do hope the treble hardness and brightness goes away. How long does this take?

The GTX D Gold had boomy low bass but I liked the top end on that. Overall, if I had to choose one among the 3 outlets, I prefer the Maestro so far.
Heh.  Anywhere from 200 to 400+ hours, depending on resolution of your system.  Yes, 5 hours in is when you start that painful burn-in.
Yeah, the bad news it does take time for the 'extra' treble to stop.I cannot say exactly since I kept adding more Rhodium plugs and outlets over a few months. So I had a long long time with it. It will stop.
