Room for improvement
In order to use the NT-503 over the Home network, this app is the only thing that can control it. It works but there are lots of room for improvements 1) AIFF is supported when using the HR Audio Player on computer, but it just freeze everything when I try to open it through DLNA on this App. Need to reboot the NT-503 to gain access again 2) Album Art is supported in ALAC, hope it is also supported in DSD file format too in the next update. 3) though it supports iPhone 4 too, wish next version has a hi res display support for 6, iPad or later. Hope it is like the HR Streamer look but currently that one does not support NT-503...
