Unfortunately I lost all my Led Zep, Deep Purple, and Black Sabbath albums in one the moves overseas and I find digital copies and reissues of those albums unlistenable. Not that the originals were all that great but much better than what I have today.

On the reissues and digital the bass is all cut off. The original plums have such great bass. The classic records especially the 45s that Mike has are probably the best.
