Thanks, yes, I should try that to see what the result is with EXACT mode enabled. I assume playback would not have the white noise which occurs when doing PCM2DSD on the fly.
I have 400K files and 20K High-Rez PCM/DSD; I'd rather leave the files as is, rather than pick and choose, and play to a PCM2DSD zone in JRMc when I want to. Mainly I use a native rez zone.
