Yes.Do you use a projector?
The HTPC serves triple-duty by housing and running the RAID, running Emby Server, and also Emby Theater. It's connected via the AVR to a projector. I have used it to stream to the living room TV via AppleTV, but that's rare. The bedroom TV only has a TiVo mini so can't stream from Emby.
As the media PC is in a dedicated media room, I don't hang out with for general music listening while web surfing. But I do spend an inordinate amount of time fussing with the software, twiddling metadata, and generally wasting my time being an HTPC hobbyist.
