This may not be relevant... I just purchased a well worn (lp) copy of Country Joe & the Fish, "Electric Music for the Mind & Body", VSD.79244 at a record show. Visually, it has lots of superficial surface scratches and other issues. (I can just imagine how many parties and "good times" this lp has seen). After a good cleaning it really sounds fantastic. Here's the kicker, it is a 3E/3F copy. I can only imagine how a clean 1A copy sounds? I think Speakers Corner has reissued this but haven't heard it.
I do have a Speakers Corner reissue of Janis Joplin "I Got Dem Ol' Kozmic Blues Again Mama" that sounds better than 97% of the stuff I hear these days..
Here's an interesting note: I have, as part of my security system, some glass break sensors. My listening room has one. This room is so well damped, it really takes a lot to trigger this sensor. On records like this one, it is triggered easily. The dynamics are really superb.
