Replacing generic RECEPTACLES

audiosens........I will be installing 3 Furutech GTX -d r.   I see  that the GTX 105-D  Wall Plate  $220.....The GTX Wall Frame is $160.....Thats $380....Plus the cost for each of the Furutech GTX-d r....$250 x 3 + $220 x 3....+ $160x3 = $1890 .....Wow that is alot for 3 total receptacles...  How important is the wall covers and wall frame ?????

audiosens........Also i just forgot , 2 of the Furutech GTX-d r  will be going into a 2 gang wall box, and will need a 2 gang wall plate. I will not be able to use the covers and the frames for those 2.  Looked  to see if Furutech has the 2 gang wall plate... They do not have it. 

In my research the most important element seems to be a layer of carbon fiber on the cover to protect against RFI and vibration.
Some forums recommend using a non-magnetic stainless steel cover. Available for quad receptacles.

These were highly recommended for duplex outlets...

Furutech 104-D Carbon Fiber Hi-Performance Duplex Outlet Cover Plate

Oyaide Electric High-grade Outlet Wpc-z

You can always purchase the Furutech outlets now and install them and then down the road get whichever wall plate you chose.
The bigger question is which Furutech outlet best suits your needs?
The Rhodiun, Gold or NCF(R)?

Are there any Carbon Fiber Quad Covers? Ive been looking on line but cant find any....
