I agree on Angel in general, but they released some limited editions Classical in that time frame in 45 RPM that were pretty good. I still have a few of them around. But even in the 60's the golden era for RCA Shady Dogs and Mercury Living Presence, The Columbias Classical were the worst. The records were nice and heavy, nice vinyl material, but they were terribly over miked and just did not live up to other Columbia recordings of that Era. The Jazz and even the rock in the 6 eye era, or even the later singe eye series were great sounding. The Classical just did not sound good. The RCA and Mercury actions to keep it simple made for terrific recordings.
