@hilde45 In my trip of chasing and getting bettet sound I found that not all Power Conditioners serve that goal well. Just as not all cabels are created equaly so goes it with PCs ( Is that PC to say?).
The Audience PC may/may not make a difference to you where as another PC might?
Can a 5k+ power cable make a difference? Your ears will know.
My science teacher played Pink Floyd for me. He was cool.
