Problem with any non Jriver type player is, the headless support is not great I guess.
I'm hearing these players are the cream of the crop when it comes to sound quality (upsampling or not): HQP, MQN, Bughead Emperor.
Miska from HQP has mentioned on ComputerAudiophile that his player won't perform optimally on Windows 2012 server. Unfortunately most state of the art music server is built using WS 2012, audiophile optimizer and paul pang stuff. So, this is unfortunate.
So, my question is - whats the best audio player that has superb sound quality and has reasonable headless support (android/iphone app for example) and can perform optimally with WS 2012 OS? DSD upsampling would be a bonus.
