Best steaming DAC with room correction

OH, almost forgot .... miniDSP now has streamer + Dirac Live units here:

The miniDSP SHD is a streaming DAC/preamp with Dirac room correction. It also allows integrating subs. I have an SHD and can report that the streaming is reliable. It uses the Volumio streaming software, either with its own app or as a DLNA renderer.

The NAD is less flexible, I believe, when it comes to adding a sub or subs. Also, it uses BluOS rather than DLNA. Many like BluOS; I have no experience with it so can’t comment (so obviously have not heard the NAD either). Definitely worth considering.

The Anthem STR is a very nice DAC/preamp with ARC, Anthem’s room correction. For a few hundred more, one can add an Allo DigiOne SIgnature player to provide the streaming. I’ve built an Allo unit from their less expensive board and was highly impressed. That also would use Volumio, so either DLNA or Volumio’s app.

I own an STR Preamp and like it a lot.

The DSPeaker X4 also fits your budget and has gotten good reviews, I think.
I hope that helps. Good luck!

Thanks for the recommendations; Chromecast audio was fie to start out with but I feel I can do better with my current setup.
