I remember reading about the DSD system a few years ago... is anyone actually using it?
Yup, at the school I work (conservatorium the Hague) they train musicians to become editors and engineers behind it. Pyramix is the standard in 'the old acoustic repertoire' where (a proper reproduction of) roomacoustics are vital.
Classical music, you know. Big fat screaming tards, sweaty old farts wavings sticks at pinguins playing violins, that stuff.
