I want to master some classic amiga and PC mods to utmost quality possible today.
The best way to play Amiga MODs would be to completely disable sample interpolation and set the playback rate to, uh... 28 point something KHz, actually.
And yes, you're exaggerating. It's not like you are every going to hear the difference between 44 KHz and 192 KHz, or 48 KHz for that matter. And 384 KHz is definitely over the top. If you want extreme sampling rates, 96 KHz is already enough, but be sure to use at least 24-Bit output resolution as well then.
