How Important is power conditioning if you have

I don't use any conditioning at all. I tried passive conditioning and it added a veil over the presentation so I took it out. I have dedicated lines with PS Audio Power Port Premier outlets and PS Audio Power cords.

Dedicated 20A lines here, one for each amp and one for front end gear. Electric enters the neighborhood through a transformer and then routes to the houses underground. I use an Isoclean 60A on the front end and amps directly into the wall. Everything sounds great. I had a BPT transformer based conditioner before, and couldn't really hear a difference after switching to the Isoclean, since there really wasn't any noise to begin with. I can hear sonic differences between power cords, but none of them sound "bad," just different from each other. In my system, the dedicated lines and the equipment's own power supplies seem to be getting the job done.

I agree with Audiooracle. I too have (2) 20A dedicated lines with fancy Oyaide outlets, but Running Springs power conditioners are awesome, the best I have heard, and I've heard quite a few. I didn't care for the Running Springs power cord though, put an Elrod EPS-3 Signature on a Jaco or Danielle and you are set!

That said, I haven't tried the newer, higher priced Running Springs power cords.

If you already have good clean power there is no need for a power conditioner. I have tried many power conditioners with the same results as Taters and Kurt_tank.

I have two 20 amp direct lines and upgraded outlets. My BPT 3.5 Signature is by far the best improvement and a must for me and my system with direct lines.

I use the BPT on my preamp and digital front end only, but the improvement is astounding. I live in a smaller Midwest town in a new house.....
