Recently started getting more serious about my home theater. Always love the gear my father has and now finally have the money to invest in a more serious system. My current setup consists of Pioneer elite SC-55 av-reciever, 2-BP-8080ST, 1-CS8080-HD, 2-SR-8080BP, and 1-Supercube 1. Everything sounds fantastic, definitely an upgrade from my previous equipment. The only thing I'm curious about is if my system would benefit much with additional amplifiers for the towers and center? I was looking at Emotiva or possibly outlaw monoblocks. Also curious if anybody has had any noticeable improvements with spikes or cones?
