Digital isolation. Am I doing this correctly?

I used to have my amp and my cdp plugged into my Audio Magic Stealth. Cdp in one outlet (left side) and amp in outlet on the right. Since purchasing my Stealth, last year, Audio Magic came out with a Mini Digital. I have purchased the Mini Digital and the (they are on the way) new Matrix. Now I will be able to isolate these babies properly. Does it matter if they are both plugged into the same wall duplex outlet? Will I achieve the isolation I want, or should I plug one of them into a different outlet? Thanks in advance. peace, warren

P.S. review to come, of course, after I burn these babies in. Takes a good 300+ hours. I do them apart from my system with some high amperage (vacuum when I'm away, space heater when I'm home) stuff, to really get them cooked, quickly. I will keep you posted.
