I have used many power cables in the past, I am now only keep 1 in my system....Russ Andrew classic power chord. The reason I am keeping it because my Cdp is using a choke regulation technology and I can hear some improvement, not a night and day different by any mean, just a very very tiny improvement, value for money is about 3 out of ten!. I also have try some expensive ones and expected the miracle improvment to the sound of my system and I am sad to say "my jaw remained firmly in the same location as before". Please note: when I started my hifi journey with budget system I thought I heard more improvement back then (russ andrew yello cables) so may be the higher spec gears has a better design power supplies and therefore they could have no need for them! (or could it be my imagination!)
