The choice of wall receptacles


I am in process of running two dedicated circuits for my audio system. I will be running standard romex 10/2 wire point to point and will make the "upgrade" at the receptacle. The products I have read up on are as follows:
1)Wattgate
2)Furutech
3)PS Audio
4)Acme Audio Labs
5)FIM
6)Hubbell
7)Oyaide
8)Home Depot ($1.59)

My system consists of Bryston 7BSST Mono's, CAT Ultimate MKII pre, Nakamichi OMS7a cd player ( to be upgraded when I can decide what unit to purchase and how stable the cd outlook may be), B&W 801 Nautilus speakers, Audioquest Volcano speaker cables and Audioquest King Cobra interconnects. Please I am strictly looking for "SOUND" advise and not a slanted SALES advise. There is listed here 7 receptacles not including the basic Home Depot version. Any one with experienced listening got advise? Thanks.

Uppermidfi, that is correct. The Oyaide's price per receptacle I believe is not quite $100 per. I am also interested in learning more about the Porter Ports. If $200 is spent on receptacles, regardless which ones and the improvement is noteworthy then is it not worth the investment. We sometimes give more attention to true high end components and spend much more $$ for maybe a slight improvement. My goal is for a purer sound and I do not have any to A/B compare except fot the standard ones.
Answering to the response to the outside line feed I have chosen to draw the line at the wall receptacle fed with romex 10/2. Again your advise is much appreciated.
I have bought several cryo outlets from Alan at AudioExcellenceAZ, and can't speak more highly of the product or Alan. Having tried the PS Audio Power Port, I had talked with Alan about how bright the PS Audio made my system. I got a mini-education in the difference that nickel makes to the sound. I went with the Hubbell 5362 in my wall outlet and in my PS Audio Ultimate Outlet. He does an extended cryo treatment and then cooks the outlet as a sorta burn-in process. The 5362 gave a more detailed presentation wherein the increase of blackness was shocking, and due to the lack of nickel, the sound was very smooth and quite musical. Check it out at:

Good Stuff!
I have a few (4) P S Audio outlets, and I think they are easily worth the $200 cost, but if I had it to do again, I would get Porter Ports based on what so many of his satisfied customers have said. I'm not sure I got anything more with the PS Audio, but I certainly spent more.
