Hello I have a Pionner VSX-806rds DPL receiver and a pair of Cerwin-Vega E-315 front speakers. I'm having some problems on deciding what to get next. A pair of CV satellites with a centre speaker for about $200 or a used Inter-M R500 Power amp for about $200 for the front speakers. I use the rig both for home cinema and music. What do I get? The power amp or a centre with a pair of CV satellites? I haven't really thought of changing the receiver out for a different one right now since it will cost too much, besides this one has good power reserves and handles these speakers pretty well. What do you think?
