Check out used Bryston BDP 2 for a streamer. There is one on audiogon for ~$1k. Add a good DAC for another $1500K and you are in fat city. The BDP will stream Tidal or Qobuz through the Manic Moose interface and play via MPD. The Manic Moose interface is seriously spartan but it works and the SQ is top notch. Then if you really get into it you can add Roon on a Sonic Transport for another $1000 plus the Roon sucscription , the BDP 2 can be configured as a Roon endpoint. The Sonic Transport and Rendu solution is also another good suggestion but I Think the BDP/MPD combo sounds better than Roon.
What do I need to spend coming from an all-vinyl setup?
I'm planning to branch out to digital (streaming through Tidal/Qobuz, not hi-rez file downloads) and was wondering where I can start to have a good chance of being satisfied? I'm not religious about vinyl or anything like that and I've heard some really good digital at other people's houses but I've enjoyed collecting records but that's probably coming to an end as we plan a move later this year. I'd probably need a one box solution because of space limitations. Any suggestions?
