I started with a Raspberry Pi, which worked quite well, then "traded up" to an Aurender, which didn't. I dumped that in favor of a Bryston BDP-3 and have been happy ever since.
For those that have separate Streamers & DACS
What are some of your favorite streamers/servers strictly from a sound quality perspective? Please assume a stand-alone DAC. I've read such a variety of opinions on streamers and was interested in opinions from those that have tried different streamers on with their DACs.
