Okay, I am confused -- particularly since the Bricasti M21 and the PlayBack Designs MDP-6 are the two DACs I have been most impressed by, albeit based only on what I have read. I thought that the M21 was "good to go", allowing me to plug in and then be fully able to listen to streams of music from Qobuz and Tidal. Apparently, that is not so. I also have a Roon Nucleus+ on my network. Will I still need to purchase yet another component before I can utilize those two services if I were to buy an M21?
