If anyone has to work at different sample / bit rates just try them out first to see if there are no bugs at that level. Seems to me that a fair amount of users of the higher 96 or 192 get a fair amount of problems that other users don’t experience.
32 bit audio benefits. Don’t think there’s much in it but I do set Cubase at that + 44kHz. If your ears can hear it then use it if it sounds better. Psychologically my head secretly thinks that using 32 over 16 means I get less bugs. But that’s just me and my monkey.
