i'm ready to update the HK 635 I bought with my ascends (3xCMT340 for LCR, 2xCBM170 for rear, HSU VTF sub), after many years of fine listening.

Our main use is home theatre for roku streaming video (netflix and amazon).
Rarely (but i'd like to make sure it's enabled) is streaming from a macbook or thinkpad using HDMI.

Other sources (only occasional) a laptop via HDMI and a DVD Blue-Ray. So lots of inputs aren't important.

THe only reason i want to upgrade is that some streams are sent in some kind of "Dolby Plus" the HK 635 doesn't do. But if I can improve, I'll go for it. I'll spend what I need to, if that's really what it costs to get a difference I can hear.

Some features I'd like:
* Really clear dialog and good music from video both
we like dramas with great music
(lots of modes of signal processing are a toy, i want to set it and leave it.)
* multi-location auto-equalization (the room is awkward)
* Bluetooth and wired play from iphone, android, ipad
* DLNA etc
* low power draw when not making sound
we're lazy and don't turn off the amp

Would be nice, but not important:
* second zone powered stereo of the same source as Zone 1.
(Turn on/off the movie in the kitchen)

vaguely interesting for future:
4X upscaling (maybe if i go 4X I should just wait, or buy something else), 3D pass-through (but right now, i'm switching sources through the TV)


Some questions:
bi-amping the 340 LR is silly, right? For my sources
How much power do I need, really? the HK's rating wasn't that high
