The media is the largest changing variable in how any system performs. IMHO
I’d agree also.
There’s a huge market in reissues and remastering, and just once in a while, they get it right.
I’m not sure about classical releases but with pop, more often than not, the original CD issues from the 1980s still remain the best.
A good example is the Beatles, where more or less everything after Revolver is best found on the original 1987 releases.
With classical, I suspect that since far more care was taken of the original recording quality, subsequent remastering is usually less of a concern.
