I'm tempted to throw my hat in on this one as well.

I have listened to Lee here on AC and his recommendations gave been good. I have A/B the constructor grade and the Cryoed Hubbell. No contest. After that I went outside the box to PS Audio and really did not seem to care to much. I then tried the Black Oyaide in my Balanced Power PPC, and did not like them as much as the cryoed hubbells in my TweekGek Hot box.
The best to date was the Furutech 15A in wall from Lee. Very nice sound, a great bargain and clearly Audiophile grade outlet.
I would like to hear the Tesla as I have had a basic Leviton in wall and did not think it did anything one way or the other...
IMHO, there is a difference in quality outlets and would be interested in hearing the Tesla version.
