Well!

I've gone track by track comparing Sooloos to Roon. I found about half the errors. An album that didn't export, and just odd tracks here in a there. Most multiple (though not all) missing tracks per album

I also deleted one duplicate album in Sooloos. They were listed as slightly different artists, same title, but didn't list as duplicates.

At this point track totals are:

Sooloos = 12712

Roon = 12673

Difference = 39

I have absolutely no idea why the difference. At this point having spent HOURS, I'm not looking again for awhile. Still thoughts are welcome.

Control:10, TwinStore, Lyngdorf DPA-1 Preamp, Linn Klimax Stereo Amp, Piega TC 70X speakers, QNAP TS-451 8TB.

Roon setup (temporary): 2009 Macbook Pro with a 1TB Hibred Drive and 4Gigs of RAM, Peachtree Audio T1 USB to SPDIF. FLAC files are kept on the QNAP TS-451 NAS. I use Rosewill (Newegg) Cat-7 Ethernet Cable on all connections.
