HK AVR 2600 or 3600?

[blindcat87]

I think I may finally be able to manage a receiver upgrade this year if things go well. I am pretty well settled on HK, while I had thought of going back to Denon, I would have to spend signifigantly more to get the lowest level Denon I would want and I think the HK sound is the best transition from the digital amp sound I've come to love but sadly can't get in a full featured receiver.

What I am trying to decide is if I should save up a bit longer to get th AVR 3600 instead of the AVR 2600. As far as I can tell, the only differences are the inclusion of the iPod adapter, which I doubt I would use even though I have an iPod, 15 watts per channel which, even with HKs accurate power ratings isn't that much of a gain, and the second room features which I would never use. Oh, and preouts for outboard amps, which is the only feature I might have a future use for, but likely not for quite some time, probably years, barring a major windfall that would allow me to go with separates. Are their other differences I have missed? Better power supply? Differences in the amps beyond the slight increase in power? While part of me wan'wants to get the better model, for that matter, part of me wants to save even longer and try to go for the 7550, I just am not finding a compelling reason to spend the extra money unless someone who knows more about the units than I do or who has used or auditioned both can give me some information that might change my mind. Any input would be greatly appreciated. I am still quite some ways out from actually pulling the trigger, so I have plenty of time to mull over the options.

Thanks,

Chris
