Finding the provenance of the music one buys is often challenging, but I prefer to source pure DSD because, to my ears, it is superior to PCM, even high-rate DXD.
Generally, analog tape masters to DSD produces some of the best material I’ve heard, with DSD128 providing a little extra detail and ambiance over DSD64 from the same source material. I have heard a couple extraordinary DSD-direct recordings (eg. David Elias: Acoustic Trio DSD Sessions from HD Tape Transfers … quite amazing even if the music isn’t to taste) but they are rare because of the limited mastering capabilities of DSD and the ones I’ve seen are limited to DSD64. (Some like Blue Coast are recording in DSD256 but mastering in analog before going back to DSD256, which to my way of thinking requires an extra DA conversion over just recording directly to analog.)
Then I got to thinking: the Directstream provides bit-perfect volume, so couldn’t Ted and the other talented people at PS audio produce a pro AD converter that could record in DSD128 or even DSD256 directly, and provide fade-in and fade-out and maybe even equalization?
