HiDiamond Power cords...

Fplanner2000, You were right on!
Placing the P4 on the CD/Dac is a big sonic improvement.
I thought that placing the P4 before the Power Conditioner would benefit all of the components plugged into it, but I guess I was wrong.
Next, to save up for another P4 for my Preamp.

Do you have 1 on your amp? If not, that's where the next P-4 should go.

Really, before the Preamp?

Hi Ozzy, on my system, I would definitely follow Harve's recommendation.... My Rowland Criterion Pre being markedly less sensitive to PCs than my Rowland M725 amps. Guido

It all depends on the component. In my system, DAC is the most sensitive, then pre and last is the amp.

Ozzy, since you only have a stereo amp, you can try on both.
