power cord replacement...source or amp first?


is there a general rule of thumb as to where an aftermarket will make the biggest sonic difference? i have one (ps audio) that i have been using with my simaudio i-5 integrated, but i just moved it to my arcam cd player. i have another one (signal magicpower) on order, but wonder if there's a general rule of thumb as to priority when replacing power cords. source or amp first? thanks.

Anytime you can improve the source, everything downstream benefits. However, in this hobby, the rule of thumb isn't always perfect...Try both cords on both and see what synergistically sounds better....
While they can help on any component, our experience is that they are most effective on transports/DACs/Phono Stages - then Pre-amps - then amps.

Depending on the quality of the power supplies etc in your equipment, you do have to try for yourself. The above are "norms."
