I agree 100% with Mr. @hilde45 and he is being quite humble here. Dedicated lines are the way to go. Get all the noise off the line feeding your listening space. When I built my house 25 years ago I did this. No need for conditioners and I only use distribution.
What difference do power cables make?
I’m considering a purchase (about $1000) that will include a power distribution box and a couple of very good cables to service my power amp and subwoofer..
For those who have upgraded power cables, how you would describe the sound quality difference in your system?
Do you feel that it was worth the additional investment?
