my dealer should arrive shortly. I've just spent the last hour disassembling my gear so he can get to the outlets unobstructed.

I have 10 of the previous model GTX-D (R) with Oyaide WPC-Z outlet covers. since I'm doing this upgrade I'm also upgrading the outlet covers to the Furutech GTX outlet frames and 104 carbon fibre covers.

I wonder how much tearing everything apart will impact the settling of the Tripoint Troy Signature and Entreq Silver Tellus and Poseidon?

if I like these i'll do my 3 other outlets (one is a 4 gang set-up for my tape decks).

Congrats Mike. Look like pretty fancy outlets.

One question if you know or can ask your dealer:



What is that shroud on the right around the terminals. I have not seen that before. Is it to keep the wires at 90 degrees to the outlet looking from the back? Or just a layer of insulation?

I plan on adding these outlets when my new 2 channel room is added to the house.the old one is being converted into a bedroom, bath and master closet. The outlet covers? I am not sure what they add to the system. They are very pricey too.

A lot! Around $350 each? Maybe you can get me a deal Amir with all your many contacts. I think the covers are over a $100 do but I will have to check on that!

btw; my dealer is our mutual local friend, Joe from Kosmic. and Joe says that those shrouds are intended to prevent short circuits inside the mount.....particularly when using spades.

how these outlets are different is there is added tourmaline crystals to the carbon fiber. it's said to improve resonance control and thermodynamic heat. tourmaline, when heated, converts energy to negative ions which causes a potential which then dissipates static. hair dryers use tourmaline for the same reason.

Then that makes sense and is a good idea especially with heavy gauge wires we tend to use for our audio gear. Heaven knows I have had these terminals come loose as I shoved them into too small of a box :).

resonance control, resonance control, resonance control.

your power cables and outlets 'sing' along with the music. that resonance is noise. better outlet covers, less noise. too bad it works that way, but it does.

Are your outlet boxes plastic or metal?
the UL rated 'remodel' 'deep' box is plastic. these are mounted into the 3/4" ply cabinet soffit-baseboard, not attached to a stud. the baseboard is attached to my 6" thick concrete floor.

no one makes an 'audiophile' outlet box......yet. might the plastic or metal box be more resonant? I'd say metal.

I just installed two yesterday that were already cooked before I put them in. Replaced the older GTX Rhodium. First few notes indicated less noise and better dynamics. These run around $250.00 not $350.00.

I just looked them up. $250 they are. I will get 2 as I have 2 dedicated lines in my room now and will in the new room. Will be without a room for a couple of months starting in the spring. Bummer but necessary. All outlet boxes I see these days in new construction are all the blue plastic variety.

Pin retention: measured as the force required to pull the plug from the outlet.

This a key consideration with "hospital grade" certification/requirements. That then, is good enough for me, having used varieties of special outlets (+ spec grades) for over 3 decades. For this silly hobby, 3 in my modded PLC, 1 stereo wall, 1 HT wall, = 5.

Hosp.Grades are generally special order items, ~$14 to $20(*). My cost overall ~$100. However, since pin retention is prone to fatigue, some, if not all, may require replacing over time. I've had outlets w/appreciably fatigued within 2 years, others much longer. Either way, at ~$20 a plug, the ongoing cost is sustainable.

Which leads me to my question ... what's the pin retention characteristics with these outlets? Has anyone tested over time?

(*) spec grade outlets offer higher pin retention qualities than standard grade, readily available at home hardware outlets for ~$7.

They say they have a spring but don't specify anything else.

Mike, please give us some feedback after you install them with respect to insertion and pull out tension/force.

The GTX outlets do not have nearly the same grip as a hospital grade receptacle, but the difference in sound is night and day. The increased grip of hospital grade is not really a good thing as it'll strip the plating off of male plugs. The GTX is designed specifically NOT to damage plated male AC plugs. The GTX also uses copper contacts, which are too soft to hold it's shape, so a stainless steel spring is used to compensate. They could have made this spring as stiff as they wanted, so I assume the retention force is very intentionally calibrated.

The cover is ridiculous, stainless steel with a coating of carbon fiber all around it, and the wall plate is very thick powdercoated billet aluminum. While expensive they hugely overbuilt and are definitely worthwhile.

Also, the Furutech AC receptacle promotion is still on, here are some prices, not including the new NCF which are $250:

GTX-D(R) - $183.75
GTX-D(G) - $140.00
Cover - $83.25
Wall Plate - $120.00

If you get them from me, shipping and burn-in are free. Burn-in on the rhodium plated receptacles will drive you nuts, it takes a long time and has a huge effect on the sound.
