I’ve had good luck with both Blue Note CD’s, and any Van Gelder reissues, not necessarily only Blue Note ones. You might try out a few SACD’s if your CD player can play them. The two I own are markedly better, although perhaps prohiibitively costlier than their Redbook equivalents. I’ve also had luck, generally speaking, with Japanese CD’s.
The price is definitely right on used CD’s versus new vinyl. I hardly mess with used records due to condition issues which CD’s are immune from for the most part. You’ll see a wide selection on Ebay.
