Yeah, I'm into mono hifi classical and jazz from the 1950's. A good performance on an original pressing has its own depth that transcends the accustomed lateral spatial clues. However, I currently play them on my stereo rigs but intend to build an all-tube mono horn rig in the future to extend my enjoyment, so additional enlightenment, to the positive or negative, may follow. Beyond about 1958 or 59, the better classical and jazz recordings will usually be found in stereo (extend this breakpoint to about 1968 for poprock). Before these dates, I've gained an appreciation for the mono releases-- especially Julie London from the '50's and '60's surf and psych, which were generally more carefully mixed in mono up to about 1968.
