Fplanner2000, Bacardi, I have tried the P4 from the wall to the power conditioner (Audience) and it is am improvement. But, my CD player (Cary 306 SACD) is also my Dac, so perhaps Fplanner2000 point about using the P4 on the CD player would be the better place.
But then again, my Preamp may benefit with the P4 since everything eventually goes through it.
It is difficult to just swap the cables behind my Audio racks but I will try this weekend.
Anyone else have any experience as to where the best placement for my single P4? All my other powercords are the P3's.
