I had a NAD Master series M50 / M52 (music vault and streamer) it sounded good through my AC200 and DSP3200 a lot better then streaming from my Mac.

I traded it in recently for the MS600 / MD600 and the jump in sound quality was amazing my girlfriend noticed immediately and she�s not a HiFi buff.

The Sooloos app is better then the NAD app but that�s a visual thing I buy HiFi for the sound, if the Sooloos app doesn�t change from how it is now that�s fine by me beats going through a stack of records or draws of CD�s.
