The MA3 is a terrific dac, but there are alot of terrific dacs out there today. The streamer in the MA3 is alot better than many would have you believe but like everything else in audio, it can be bettered. It is a nice feature to have while you are building your system and depending on the rest of your gear you buy, you will have opportunities to enhance your system once you have decided next steps.
What do you believe the rest of your system will eventually be, what is your overall budget and what are your musical/tonal preferences?
