You will have endless problems with AIFF w/ iTunes and the Bryston BDP - mostly because of the BDP's underlying use of MPD.
1) There is a byte offset issue with how iTunes manages metadata that will cause MPD to simply skip over the file on playback and/or while processing the embedded metadata. I can't recall the specifics, but trust me: AIFF and MPD don't mix, if you are using iTunes to either rip or manage metadata. Even if you rip using an external tool (e.g. I use XLD), iTunes can still go in and change metadata.
2) As mentioned in previous posts, iTunes will often keep the album art external to the actual music files. However, there is a simple fix for this, if you are using macOS.
But, really, the problems are mostly with #1 above. Yes, many of your files will just work, but you will continually encounter files that won't play. AIFF is fine on its own (i.e. outside of iTunes).
I really tried to get around these issues, but for MPD use of my BDP-1, I maintain a parallel library that is all FLAC and has been groomed to work-around the many flaws of both Manic Moose and MPD.
Also, as mentioned above, you can use Roon and avoid ALL of these issues.
