I just installed the SR Black outlets. The first thing I realized as I dug in to the project was that I was replacing not PS Audio Power Ports as I thought, but rather two Shunyata Research SR-Z1s, very robust Hubbell-based outlets which are cryo-treated in a proprietary process. I wonder who crept into my living room and put those in there? I have been using a non-magnetic stainless steel outlet cover which will be replaced later in the week by a Furutech dampened unit. All grounds were properly tied inside the outlet box per code.
Anyhoo, first impressions are that in comparison to the SR-Z1s, the Black outlets make for a much more open, delicately detailed sound, maybe slightly more forward than before, while possessing excellent harmonic structure. To use a visual metaphor, it's as if the stage is more brightly lit. Bass speed and definition is much improved over the Shunyatas as well, while extension is so far something of a wash. Soundstage depth so far seems a bit fore-shortened, however, this being the main negative I detect out of the gate, though it seems to be improving as I continue to listen.
