Ahh yes, the age old debate. Well, I'm posting this for a friend who has a pair of old Cervin Vega VS-120 front speakers. He runs them off a Kenwood receiver but it looking to upgrade that. He's wanting to know what he should get to get the most out of those speakers. He'd also like a sub as well. What would you guys recommend in the $500-$1000 range for both ampage (is that a word?) and a sub to make his room shake for movies?
