Most Beneficial Cable Upgrade


All things being equal, which cable upgrade would have the greatest sonic impact/improvement on a high end audio (stereo) system?
1)Power cables
2)Speaker cables
3)Interconnects
I have heard that power cables have the greatest benefit due to their ability to reduce RFI (radio frequency interference).
Does anyone know the answer to this question?

Back to the original question (novel idea, no?)...

Elizabeth’s original post is consistent with my experience. And I can’t say it’s exactly surprising; it is prioritizing the cables which handle the audio signal directly when they are at their most critical (ie. low voltage / current).

I have gone a step further and essentially eliminated speaker cables; my monoblocks are behind my speakers, oriented in such a way that the binding posts line up and there’s two inches of DIY copper foil “cable” in between the amps and the speakers. Always amazes me how so few others with monoblocks take this approach; the speaker cable is effectively gone (effect on sound AND the cost).

I have also found that the better quality your AC is, the less power cords matter. I have three dedicated runs of cryo’d Romex for my system. Preamp, TT, and SACD are on a PS Audio regenerator; monoblocks have dedicated balanced power transformers and hot to neutral capacitive filters. In this setup, I have tried some very expensive power cables, mostly out of curiosity, and heard absolutely zero difference...no joke. In lesser setups, such as when I was an apartment dweller and couldn’t have dedicated runs, there’s absolutely a difference, sometimes large.

So maybe the best way to prioritize cables is to do what you can to eliminate them altogether or reduce their effects? Just a thought.
