It sounds to me like you might be better off with a AVR. Most two channel units like to play on the analog camp and may not have the necessary connections to make NAS use and other things easy. Many AVRs these days near $500 and up also do music very nicely. Many AVRs have media streamers on board. Finding what AVR has the streamers that you need is the big issue. Also, if you are playing records (vinyl - as many audiophiles refer to it), quite a few AVRs have a phono input again.
