Hi Nick
no - I have never tried them. Nearest I've been to PSU changes is my use of a PS Audio PPP and a modified SB3 (SB+) which has a PSU in a totally separate box.
My comment above merely references the 3rd reply in this thread which offered some warnings. Seems the experience found is not an exception for these people.

cheers

(come on England...just 2 wickets !!!!)





Rgds,
Nick
