The Chesky LPs are uniformly fantastic. They have a way of expressing classical music that is the closest I've ever heard to the sound you'll get from a warm sounding opera or symphony house. Too bad they've stopped making these.
The AP issues may sound a bit better than the originals, but are beset with numerous pressing issues - off center spindle holes, terribly noisy vinyl, monstrously loud pops, extreme warps. On one test LP I have, the hole was so off-center that you could hear the once around warble in the 1 KHz test tone. Just plain awful. Straight to the bin.
The only really good LP from AP that I have is Beethoven's sixth, by Bruno Walter. I don't play the rest.
London and Decca LPs of classical repertoire from the 50s through the 80s are the best bet for great sound, especially those mastered by "G" (in the dead wax portion of the LP).
