Im currently building a house with a HT room. I have decided to go with the RTIa9's as my main stereo speakers however I am unsure as to what amplifier to use. I plan on doing full 7.1 surround with them, plus run some out side speakers off the same system eventually. Would something like the Yamaha Z11 be good enough? or should I go for more a Rotel power amp set up? perhaps with a denon or marantz pre amp?
Basically do the 9s really need up to 500watts?
