Hello. This is my first post and I'm looking for advice. For the last few years my theater system has consisted of a pair of M60s,VP100, QS4s and a EP350. I've been running that with an older Pioneer VSX1018. After researching I really think I could get more out of the Axioms. What would be the better path? Going with an amp with my receiver or update the receiver with a newer more powerful unit? Thanks for any advice you can throw my way. I'm a novice at this.
