I view both amplifiers and cables as components and I have gotten different sonic results when changing either. But I will say that it is surprising to me how much difference cable changes can make and I'm speaking of all system cables including intereconnects, power cords, speaker cables and digital cables.
I've also found that what power cord the amp uses can affect which speaker cables sound best with said amplifier.
