The 'affordable carbon fiber AC outlet wall plate' arrived today. It's well-made and obviously authentic laminated carbon fiber composite material. Quite hefty, with telltale multi-layered striations involved with this type of material. The material is exactly like the many other carbon fiber audio products I've enjoyed over the years, so fellow AA Inmates can rest assured, it's the real deal.
I recommend tightening the mounting screw with great care, since the epoxy within the laminated carbon fiber composite material is brittle. The thickness of the carbon fiber AC wall plate is sufficient enough not to be too concerned about it, but fair warning says don't over-torque the mounting screw. While vibration control is part of the equation, dissipation of stray magnetic fields due to termination of the wiring is the key benefit.

OK I got 3 I can't believe they'll do anything, but I'll report when they come in.... Beg or Mid October.
I'm looking forward to your report, SgreenP@MSN.com.
Just out of curiosity, do you reckon there would be a difference between the carbon fiber and an old fashioned metal face plate? The metal face place would obviously be conductive, but not sure if there are other considerations.
Long ago, I purchased two particular AC outlet wall plates; a thick milled aluminum wall plate, and a carbon fiber wall plate. Both were the same size and thickness. Swapping-out a wall plate is a very quick and easy thing to do, so evaluating the differences between the two was readily apparent. The carbon fiber AC outlet wall plate affected the presentation like that of a power line filter, producing a lowered noise floor which provided notably better resolution with the proverbial blacker background, while the aluminum AC outlet wall plate, while sounding better than a cheap plastic wall plate, was comparatively unimpressive.Since then, I installed an oversize carbon fiber AC outlet wall plate that I mentioned in the forum 3 years ago.

Hi Duster and Others,
New member here.
Thank you for the info you posted. It is especially appreciated as I will be doing some rewiring in my living room with dedicated outlets for the flat screen and the AV system.
Do you have any recommendations on plastic vs. metal receptacle boxes and the brand/type of 10 gauge in wall power line?
Before concerns are raised, I wired the addition to my house and the electrical inspector asked if I would go work for him. There are times I wish I had.
Also, surprised no one has made a carbon fiber receptacle box. CF and epoxy are pretty easy to work with.
Thank you,
John

Welcome to Audio Asylum, John. I think you'll be pleased to know that a carbon fiber electrical box is overkill, IMO.
A carbon fiber AC outlet wall plate placed right next to where the stray magnetic fields are produced is where the unwanted EMI is absorbed/dissipated.
A rigid molded phenolic resin electrical box is substantially more rigid than typical plastic boxes. Somewhat expensive, but not from an audiophile POV.
10 AWG cryo'd Romex is the usual option that folks tend to use, but there are more expensive products from audiophile cable manufacturers.
How many feet do you require for your project?
Thanks Duster!!!
Fortunately, I only need about 30 feet of the 10 gauge Cryo'd Romex. I had a number of Yamaha engine parts cryo'd as an experiment. The hope was that the aluminum parts would shed heat quicker after treatment. That didnt happen, but the aluminum machined very differently in the lathe. Interesting to see what the Cryo does to copper. It would be nice if it was easier to form around screw heads.
The phenolic outlet box looks good. I found a bunch of beefy outlet boxes thru Google including polycarbonate. Prices vary quite a bit depending upon the source. I'm guessing that the beefier the better to dampen vibration.
Anyone have a good source for the Cryo'd 10 gauge Romex?
Thanks,
John

The benefit of cryo treatment for copper wire is the tightening of the crystal grain boundaries for a smoother sounding presentation, not unlike the benefit of OCC single crystal copper, but obviously not as optimized.
Rigidity is a key aspect of improved AC delivery from a mechanical POV, which is associated with vibration/resonance control.
VH Audio sells the 10 AWG cryo'd Romex.

Thanks, figured there was more to it than simple conductance.
I ordered one this morning, and will be interested to hear how it impacts things. Tried some fuses, and some made things better, and some made things worse. Very happy to find the ones that improved things. Hopefully the face plate will also move things forward.
Trust your ears - nothing else really matters. Theory can be thought about, but not heard......
I don't roll fuses. A sand-filled ceramic fuse, with silver alloy fuse wire is a notable step-up from a normal glass fuse, without stepping on the sound too much.
I find the presentation simply has more body and presence, and I'm quite satisfied with the improvements it provides, for little cash outlay.
I don't mind if I blow a fuse, someday. I think that's a reasonable attitude about audiophile fuses.
I received mine on Saturday. They are as you describe them. Unfortunately, the Viborg RCA socket caps came the day before and I installed them first. I am waiting a week to do the outlet covers just so I know that the improvement is being caused by them, not any other changes to the system.
enjoy!

My three came in today. They do appear substantial. BTW, the shipping label shows they were shipped from Connex in NY.
International shipments usually get relabelled by freight forwarding services like Connex.
Cheers!
