I've never been a mono-phile. Yes, mono is better than electronically reprocessed stereo. And yes, for some of the early stereo recordings, where the engineer smacked one of the horns in the left speaker and the other in the right, it's better to hear everyone in the center. And, finally, there are cases, most notably on many of The Beatles' albums, where the musicians supervised the mono mix and ignored the stereo, making the mono, in a sense, the authoritative
version. But in general, those albums that were recorded in stereo, I prefer to hear in stereo.
But the latest excavation from the Miles Davis archive, The Original Mono Recordings, nine CDs of the nine albums made for Columbia from 195563, is an exception, a set worthy of attentionthough not so much because the discs are in mono.
