power cable

Certainly try on both. But power cords for amps tend to be different than for components. Emphasis’ for a component power cord is shielding, emphasis on a power cord made for an amp is capacity… lots of metal. 

Come on guys, you know exactly what he meant. 
 

Power cord upgrades to amps tend to produce the greatest effect, and can be huge. For instance, my Audio Research Ref 160s comes with a very heavy copper 20 amp power cord. The first and all subsequent power cords I tried were much better, but many pushed the sound tonally, ever so slightly. It took me a year of occasionally trying something different until I found the perfect match… and it was way better. It was an Audioquest Hurricane. Absolutely no tipping of tonal balance, much quieter, more dynamic.
