my experience is that hirez PCM is not even remotely close to a properly dubbed 15ips 1/4" tape copy of a tape. and really not close to a good Lp either (at least in my system to my ears).
Mike:
I have a 15 ips/2 track copy of KOB and it beats every LP copy I have, including an original Columbia and Classic reissue, hands down! :) Everyone who has heard the tape is speechless-you know the effect when a group of audiophiles stop talking and start listening :)
