Dave, I agree with you that the ENGINEERING is the problem, not the medium. With the advent of the CD, I can say that one of the WORST recording I own is on CD, and the BEST recordings I own are on CD. Now a very few people are putting 24-bit 192Khz. sampling rates on Blue Ray (hey plastic is plastic) which, Oppos currently have the best, built-in Sabre DACs. Although, according to Tom Holman (of Advent, THX/Lucasfilim, and Audyssey fame) only bats should care about that high of a bit rate, but I digress.
As tech. editor of several photo mags in the last 20 years, I was also a very early adopter of digital photography and helped (just a little) in the development of the Foveon camera sensor technologies. I have been saying that ever since the Fuji S2, and Canon 10D, all digital cameras are better than 99% of photographers.
I'm saying the same thing about the digital recording medium. It's only as good as the producer. One of my reference recordings is "The Nightfly" by Donald Fagen of Steely Dan. It was released in 1983 during the Digital Infancy and has withstood the rest of time. Since, in the right hands, that good of a recording could be produced with the primitive equipment available back then, as compared to today, there is not excuse to ever blame bad sound on the medium anymore.
The days of crappy recycled vinyl with Himalayan warps, unplayable on any turntable, along with noise from bad pressings done too quickly by greedy manufacturers are gone. Either the bits are readable or they are not, period.
So I need to be forgiven for not being the first in line to wax nostalgic about the "good ole' days" of vinyl. There were way more quality variables back then that could produce excellence or crap. IOW, a wider gamut. Like Bill Joel said: "The good old days weren't always good and nothing is as bad as it seems."
