What music file quality parameter limits are being used in the 2021 CX-9 USB ports?

I need to not only know what types (MP3/4, FLAC, OGG, DSD, DSF, etc.) can be read by the USB Source Function for Audio/video, but also the Sample rates, number of channels and the ability to play Lossless compression type. There's nothing in the manual about all these parameters. Also, you have to be careful of what type of USB flash drive you can use and how it's formatted (FAT32) and USB 2.0 NOT 3.0 and up. Currently I'm doing trial and error and it's such a pain. If I knew the limits of all these I could convert all my "Car Tunes" files to the maximum. Anyone know where I can get this info? I currently have a LOT of DSD and DSF files that are screaming to get played in a 12 speaker BOSE system. Thanks in advance.
