Once you get the Oppo/Vanity up and running, there is absolutely no reason to get the $40K ADA reference over the $15K Trinnov MC, except user interface and adding inputs beyond the 2 x HDMI inputs available on the Oppo 103D (of course, you can put an HDMI switch in front of this).
In fact, getting the MC will give you digital out, allowing you to hook up an audiophile 2 channel DAC to the Trinnov, taking up two channel performance a few more notches.
