@bongofury1956,
The disappointment is that we will spend small fortunes on equipment and purchase multiple versions of a recording (CD, SACD, Anniversary Issue, Remastered Issue, Original Vinyl, MoFi Vinyl, Blu Ray Disc, etc.) in the quest to get something that just sounds better than mediocre or worse.
Yeah, people were around the mics for Layla and Exile on Main Street (my two peeves), but either the mics were for crap or the engineer or artist had imbibed or smoked or whatever too much. Someone wasn't checking the meters.
It's just a shame. Nothing more, nothing less.
