Love those Compacts! I recently did a class reunion - about 120 people - with 2 Compacts. One of the Compacts lost sound, and I cranked the other one up to about 1 o'clock and no one knew the diff. One of the participants was a musician- a Tyros player - and close to the end of the gig I told him what happened, he was amazed, and said he didn't notice any difference ... he's lugging around a pair of old Kustom amps and is now considering the Bose.
