Just heard back from Minidsp:
1-They have submitted to Roon for certification
2-Once approved there will be a new firmware which will allow volume control. Volume control via Roon will be adjusted through the master volume control in the minidsp.
Thanks v much for this update, I've been waiting to hear that the SHD is roon ready. It already looks like a fabulous device with this feature set, and this will put it over the top. I've been using the Tidal platform on my OPPO 105d for streaming Tidal for many years (not a Roon endpoint), and have wanted to try room and bass correction too. Sounds like if I get an SHD soon, I will be able to use Roon on the SHD for streaming Tidal and retire the OPPO 105 and my pre-amp from my hifi system as well.
