Look at the Reference Recordings stuff. They have both cd's and vinyl on some titles so you could compare. Anyway, the production quality cannot be beat.
best classical redbook cds for strings and piano
Hi. I know this is a bit open ended and dependent on taste: I have a pair of Guarneri's and am interested in exploring their vaunted mid-range. If anyone can share a few redbook CDs with very high production quality of string quartets, solo violin, cello, or piano, I would appreciate it. Thanks, RK
