Hi Ronm1,
Now I'm all for better sounding audio but I've never been much of a fan for these new media processes after some informal testing a colleague and I did. Remastering yes, these processes not so much. Did a fair amount of comparisons awhile ago. Conclusion we came too was that with a mediocre rig some improvement may at times be noticeable, but if you have a good source rig no difference was apparent. Results seem reasonable to me as SHM and these processes abate errors and a good rig one would think would not get many errors anyways. IMHO of course, just glad I didn't send my $50 in.
My experience has been very different. When comparing SHM discs with their plain CD counterparts
known to be from the same mastering, the SHM was so much closer to the sound of the master I was quite shocked by the difference. This with the Magnepan system and Metric Halo ULN-8 converter in my studio/listening room.
Ever since I created my first CD master at Atlantic back in 1983, I've been saying that CDs made at different plants (sometimes different lines at the same plant) all sound different from each other and
none sounds indistinguishable from the master used to make it.
Over the years, I've sent masters to dozens of plants all over the world. And I spent a great deal of time researching which plant we'd use for Soundkeeper CDs. The best CD pressings get very close, to the point where I sometimes need a direct A/B to hear the differences. Typical pressings however, still lose a bit of focus and fine detail.
With those SHM discs I've compared, the difference (in those particular instances) from the plain CD made me at first think they could not possibly be from the same master. But extracting both to hard disk and nulling them in soundBlade proved they in fact were both made from the same source.
It should be noted that extraction to hard disk eliminated the sonic differences. This has been true with SHM/plain disc pairs as well as plain CDs pressed at different plants. The audible differences are meaningful only when the discs are played and decoded in real-time using a CD player.
Just my perspective.
Best regards,
Barry
