Power cord heiarchy

#1) Power cord from wall to amp. this is where the most pwer is used and the most improvement gained from an aftermarket cord, in a general way. Most amps do better from wall than from conditioner. (I do use Furman Ref20i for amp... but I am crazy for clarity. It does inhibit LF a bit makes it all thinner...)
#2} power cord from conditioner to pre.

Having turned into a thread on the merits of powercords, i can only say I did not believe. Then I tried some. Now I know. Same with Power conditioners. (My caviat is that I have ONLY experimented with the lower half of the price range) They can change subtle aspects of the noise result: (most folks call that noise result music)
i would say in general, my experience is that cords clarify. Powerconditioners clarify AND tighten up the LF, sweeten the HF, and lessen the strength of the LF slightly. The LF becomes leaner, tighter, less 'wool'ly. And the Lf quickly can become too thin very easily with nearly any multiples of cords and conditioners i have ever tried.
