I'd say the SR-007's main character is to be unimpressive which is very impressive at the same time. They aren't trying to force some given "sound" down your throat since their character changes on a dime with the music they are playing at that moment. This is why the Mk2/A annoys me so much since Stax should have taken this design a step further and not introduced some, quite frankly, stupid colorations on what was a pretty much blank canvas.
