Great MONO recordings

Thanks. I have been interested in getting more into classical music. I have been enjoying KDFC, the classical station in the Bay Area. I have even thought about getting an old tube tuner. Although my classical collection is small, for Tristan & Isolde, I have a very nice LP boxed set with Brigit Nilsson / Georg Solti / London Stereo, which, I think, is also really good.

I really appreciate all of the suggestions. This Shelter 501 Mono seems to be on back order, so I guess it will be a few weeks. Good thing I already have the Gil Melle Jazz Patterns from Music Matters. I had thought that the Mono cartridge would benefit mostly older recordings. I would have thought the Music Matters reissues would have optimal sound even on a stereo cartridge, as they are already very quiet pressings. I guess I'll have a chance to hear for myself in a few weeks. I just got a mint copy of Bob Dylan's debut in stereo. Sounds fantastic...like I had never heard him before. I would have thought that Bob Dylan's early stuff would sound better on MONO, as I think they were recorded in MONO...anyway, I really appreciate the suggestions and will look into these. THANKS!
