Main reason I chose N200 over 150 was the USB and SPDIF out and display.
if I had a system that had components in the N20 price range and I could swing it I would. The N200 and a great sounding DAC really is a great digital front end for someone like me who streams a lot. I still listen to FM and CDs , BluRay Audio but most of the time it is some type of stream or playing back from some type of drive.
