A little late in reporting back, but hey . . .
The Isoclean ICP-002 outlet was a most noticeable improvement over the Shunyata SR-Z1 on my dedicated source circuit: greater inner detail, clarity, resolution, faster, etc.
After reading the 6moons review, I subsequently splurged and bought the Walker Extreme SST and applied it to my panel box connections, and to the outlet connections. Not much to say except that the stuff REALLY WORKS! I probably gained 2-3 db of volume, wider/deeper soundstage, even more resolution. Just amazing.
I have since star wired my amp circuit, and have an outlet for each monoblock. I have ordered two more Isoclean outlets. They are on the way now.
