I somehow doubt ( though cannot prove ) that it is vinyl, which "does it". To my mind and experience it is rather the analog process. Classical music on an ADD CD sounds generally better than a DDD redbook CD. But the limitations inherent in the redbook processing, does not seem to capture all of what is on an analogue mastertape even through an ADD CD, even with upsampling, if you compare it to a LP or even a good commercial tape of the same original recording. At least, that has been my experience so far.
