Finally got the Mono Box from the library I work for (Multnomah County, bewst public library going, thank you taxpayers)AND Sgt peppers, at least, is so better in mono, and I don't think theat it's just that it's allowing me to hear it fresh (or as fresh as it's going be for me at this point), but that is part of it. Also been on a Howlin' Wolf kick recently, not sure what that means but he's better in mono too...Live at Alices Revisited is way better than it gets credit for, better in many ways than London Sessions, but London is more interesting in a coulda/shoulda/woulda way, Alices is just the man live, great but it just is what it is. If Quad is 4 and Stereo is 2 and mono is 1; HW Live in Cambridge is next to 0 in terms of sound quality but it's a way fierce performance, way more than any Muddy I've heard and I love Muddy...
