Nostalgia, Hyperbole, etc. But some of the old DVD-A I have sound damn good.

OP
I wholeheartedly concur!
I have an Esoteric DV-50S and a fair amount of DVD-A discs and some are just mind blowing.
Especially the ones remastered by Steve Wilson like the King Crimson and Porcupine Tree discs.

I tend to buy them whenever I see them if not stupidly priced.
