I am thinking of a new AV set up in a small room, about 10 x 13 ft, high ceiling about 10 ft

So far i have been using a media player ( AC Ryan) connected by HDMI to plasma HDTV.
RCA out to stereo amp and pair of spkrs sometimes, for music.

I am beginning to store movies n vids (and music) in a Synology NAS

I am prepared to go 7.1
So will need an AV receiver preferably with network connectability.
Dont think i will need a v powerful AVR.
I do not have any suitable spkrs at the moment.

Advice will be most appreciated
Thanks
