HiDiamond Power cords...

@Fplanner2000, So I have my P4 on my QLS 9 to wall Teslaplex SE. You think I'll get better results with it on my Integrated Tube amp or my Opp 105(Pre-amp)? Should the P4 also go directly to wall Teslaplex SE outlet then to source.

Fplanner2000, Thanks, I'll give it a try this weekend.

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?
