I totally agree with Tvad and Warren. IMHO PC should not change the tonal balance of your components, nor should IC's or speaker cable. If they do its because they are not neutral (tonally) and are actually degrading the signal. They may superficially "sound" better, but when you eventually change out the component that is the cause of the problem you end up having to change out your cabling to match the new components. The only reason to change wire is for increased resolution. IMHO.
