Long time lurker first time poster here at AVS looking for a little direction on my 2 Channel setup that I will be using mainly for watching occasional movies, ps3 and listening to music. I'm planning to purchase the KEF's Q900's, + eventually a sub, powered with a Marantz SR5005 or HK 3490. Should I be looking at any other devices to enhance my listening pleasure as far as cross overs etc.. The reason for the SR5005 is that it supports ARC and if I ever wanted to switch to a 5.1 setup years later I would have the ability to do so. Would either of these receivers be a decent match for the Kef's?
