Happy new year, all!
I'm looking to update my very old system. I have a few pieces that have served me well, but a couple of items are sorely out of date. In particular, my integrated amp/preamp.
I'm using some B&W Matrix 801s, which, while wonderfully true on sound, are power hogs. Hence the need for a specific kind of product:
Any suggestions for a good AV amp/preamp that supports 7.1, has HDMI inputs/output, allows for a pre-out on main speakers, but has integrated amps for the other speakers? I know there are a lot of other bells and whistles out there nowadays, but that is the minimum functionality I need, and I can compare other features later.

I am just having trouble finding a good starting place. If possible, I'd like to stay under 2k.
I just don't know who the better manufacturers are any more.
Many thanks, and best wishes to all in the new year.
