I use a Bryston BDP-2 (streamer/storage) BDA-2 (DAC). They just released a BDA-3 so you can find BDA-1s and 2s here on Audiogon and hifishark.com. In my opinion, Bryston makes a high quality product and has excellent customer support.
You can also build your own using a raspberry pi and hifiberry DACplus combo running volumio for less than $200.
