My only direct comparo was between the Plugged Nickel LPs and the compilation CD that was issued at the time. The CD sounds good, but with the Mosaic box LPs you are IN the session-- remarkably vivid & alive sounding, even relative to the best Miles SACD I've got (Classic's Cookin'). I've got Mosaic's boxed-set LPs for Plugged Nickel, Studio MDQ '65-'68, and Complete Columbia MD & JC; they're all top notch.
