Try looking as some blu ray players. They can stream music or play via USB, SMB, DLNA etc. Not much available for streamers below 1000 and I've seen zero till the one you mentioned with HDMI. Someone else asked this question while back, search the threads.
Sony's two 4k blu ray players can play files from a home network. x800 and x1000, the cheaper x700 probably can as well. All with HDMI.
Did you try your Denon? It will play from music servers as well has airplay.
