I bought one of these recently:
I bought it hoping to use it to play music files from my network. I thought there might be some advantage to the newer audio codecs. As it turns out, I haven't been able to get it to navigate my network in order to get to the music files. I don't hear any advantage to the newer codecs either. Perhaps if I did a side by side comparison I might hear a difference but, basically, they are underwhelming. Nice receiver overall, however. Perhaps it can navigate my network and I just haven't figured it out.
