I spent an afternoon listening to a stock Cary at a dealer, using the R10. The midrange was absolute magic. Full and lush. However, the frequency extremes were another matter. Percussive effects were awful. Example: On the album "Hooker 'N Heat", John Lee Hooker kept the beat by pounding his foot on a specially built plywood platform. Properly reproduced, the "stomp" is a complex sound that has a lot of impact and drives the music. On the stock Cary, it sounded like a piece of cardboard. Soft, no attack, no definition, no impact. Ugh. Maybe tuberolling would have helped.
