I am having an extension built to incorporate a home cinema 3D system. I have already decided to go for Bose AM10 speakers but cannot decide on an Amp. I have a budget of up to about £800 so was thinking either an Onkyo SR608 or the new (as yet unreleased) Denon AVR2311. I currently have a Denon AVR1707 which has served me very well but the Onkyo looks so much better value for money. Should I go for the Onkyo based on its price or will the performance of the Denon justify the approximate £350 extra. Please help! Thanks
