I've been using the new WDM driver since it came out and despite a few latency glitches it works really well. I view and listen to almost all of my media via various streaming services so this has been a godsend. It has allowed me to move away from the hardware DSP cross overs and filters I was previously using with multiple DACs and recoup a bit of cash by using the MC DSP and a behringer audio interface (both excellent).
The only very slight thorn in this setup is that using my MC remote control doesn't give a visual reference to the MC internal volume when away from either the MC interface or the theatre mode. What would be ideal is to integrate a slider into the MC tray app for easy access without the remote or have some numbers pop up like they do in the theatre mode when using a remote.
Cheers
