Thanks very much Albert and Doug - your experience with these 45 rpm issues is exactly the help and encouragement I needed.
Quincy, thank you. The reason for my caution is that I have most of the Classic Records classical releases in 33 rpm and the mastering is variable (some are very good, some are bright and harsh). Most of my pressings are the 180 gram, but as best I can determine, the 200gram pressings have not been remastered - CR is using the same metal parts. The 45 rpm versions would have been separately mastered, so there is no way to anticipate the results (for better or worse) based on experience with the 33 rpm versions.
