I suspect most classical recordings are done at 96K because that's how they've always been done, starting back in the days when ADCs did not employ oversampling. The earliest digital recordings were classical pieces, and although some of them were pretty good, far more were not. Digital audio got a bad reputation back then as a result.
I know you're a proponent of high sample rates, A1. I am not here to tell you not to do it. In fact, your interface might do 96k better than 44.1. But that's a quirk of the interface, not any intrinsic superiority of the faster rate.
