ESP/950 are a strange headphone. On my first pair the squeal would mostly stay in one channel, but would then move to the other channel intermittently. The second pair were fine, but I didn't put too many hours on them.
One nice thing about some of the Japanese CD reissues (including some SHM CDs) is they often try and replicate the artwork from the original LPs except in CD sized prints. I suppose worth the extra money to some assuming the mastering is good.
