I would look to any of the mid to upper models from Denon(28XX and up), Onkyo(8XX and up), Yamaha(1900 and up), H/K(2100(?) and up). They all have great avr's with good feature sets right now. You can add an amp to any one of them (IIRC) at a later date if so desired and then when the features of the avr are no longer desireable and it's time for those updated features you can then move onto a separate pre/pro.
