Pop on over to the forum at Audio Asylum and check out this heartwarming discussion on receptacles as they weigh the relative sound quality of various receptacles.

Example:
"Any of the P&S receptacles I've experimented with (5242, 5262 and 5262A cryoed) all exhibited the hashy, splashy high frequencies relative to a cryoed Hubbell 8200H. To my ears, as yours, the Hubbell's midrange is more relaxed, but, equally important, it tends to be more open, more detailed and less "congested". I can tend to see why some might prefer the P&S's bass quality, but to me the "tighter" quality of the bass on any of the P&S receptacles will result in a much leaner presentation which I am not really fond of."

I am going to start a topic of my own-
Best quality wire nuts.
I find that Ideal's wire nuts present a creamy and forward midrange with expansive highs about 10k. The bass is chocolately rich and it embraced me like a French paramour.
I joke. But maybe some of these guys CAN really hear that well. For better or for worse.
