I have a NAD M51 and looking for a network player/streamer to feed into it. I want to play FLACs from a NAS and control it with an android app. I was initially planning to get a used UltraRendu but found out the MicroRendu and UltraRendu don't work with the M51: http://docs.sonore.us/microrendu/microRendu%20Known%20Issues.html. Is there any other streamer that can match up with the UltraRendu's sound quality in the <$1000 price range? I dont need wireless - wired RJ45 connection is ok.
