Reality check:
Unless PG Music is going to re-record all of the samples at 96kHz 24 bit, they would have to upsample the existing audiophile files. Well, any of us who need the existing files at 96k can do that ourselves.

As it is the stone won't be squeezed for more DrealDrum "stems" in a hurry, which I'd have thought easy enough as they ought to have been recorded in the 1st instance. This makes me suspect that original, premix, files may have been erased for space and that, most likely, trickles a little. Upscaling, like upmixing, is used, in the main, by con artist/floggers.
