The problem is, the wv file is basically a container containing compressed audio. Quoting from the wavpack page
and, further,
Basically, one doesn't know from the outside what a wv file "is". MPD passes the wv file to the wavpack (or ffmpeg) decoder plugin to decompress it and, ultimately, determine what the format actually is.
Tim mentioned the helper program mediainfo, which moOde uses to get information about audio tracks (but I'm unclear where it's used and where not).
Here's what mediainfo reports on the sample file of yours that I talked about earlier
This looks like it could be the source of the rate/depth info we see reported on the Playback screen.
OTOH, here's what mediainfo reports on a straight DSD file (on another computer)
Like the man says, investigation needed to see who is telling what to whom, when, so to speak.

Kent
