Recently purchased a set of RtiA9's and looking for advice on hook-up and recommendations on amp.
My current amp is a Pioneer Elite SC-68 at 140 W/channel running in 7.1.
Surrounds are polk F/x's, with rears being R50's.
Presently I have the A9's biamped from two of the spare channels offered on the SC-68 (SC-68 can do up to 11.1).
Reading through some of the forums here, and elsewhere, there is conflicting opinion on the topic of the A9's requiring more power than 140W to really shine. The Elite series excels at delivering actual rated power to all channels but I have read that you should drive them with at least 200+W (i.e. Emotiva power amp, etc).
The SC-68 is a beefy amp being Pioneer's flagship model, but is there much added benefit to investing another $1000 in the poweramp or is it simply diminishing returns at this point? At the moment they seem to sound great but I am curious what the difference, if any, when driving them at 200W vs 140W. They are already ridiculously loud from the SC-68 without any distortion as it is.
Anyone here have any experience running the A9's off the Elite series amps?
Secondly I was wondering if biamping them from the SC-68 had any real benefit or not. I have tried them both biamped and not and did not notice much of a difference sound wise, in either clarity or power. Any real benefit to wiring this way versus not (i.e. speaker longevity, damage, etc)? I have read that biamping is not really biamping unless you willing to bypass the internal crossover in the speaker by wiring it direct via an external crossover. Any thoughts, advice?
