That's my view too, and good sound is not about maximum power output, it's about minimum power output. I.e. how does the system get from (near) silence to making music.
Agree with both posts. In my experience to get anywhere near to a 'musical' AV receiver/processor, you need to be prepared to spend at least £2.5-4k if buying new. Primare AV kit has been mentioned and I would go along with that. Their HT range is pretty special at the moment, although far from cheap.
Simple AV kit done well seems to work best.
