Unless you have difficult speakers power amps are relatively unimportant.Preamps are much more important because they bring focus and coherence.
Unfortunately most preamps are crap,and of course you don't come to realise this until you hear a really good one.For me this revelation came in the form of Supratek preamps.
I am currently running a $5000 US Supratek preamp with $400 kit chip power amp-and the sound is far superior to any other combo I have owned or used which contained expensive power amps used with ordinary preamps.[including ARC and Metaxas]
