What defines progressive aprt from classic. I listen to 99% rock from eagles, Aerosmith, Seeger, Fleetwood Mac, Who, and such more modern groups like, Everclear, Train, Cold Play (their CDs area terrible Mix), Nicleback (don't have any CDs as they sound very compressed). My system is built around Vandersteen 2CE sigs. When i bought speakers it was between those and some Maggie 1.6s. While the Maggies seemed to be very tonally accurate, they did not have the punch that the Vandys had. I thought that the Vandys would sound better on the type of music that I listen to so I chose them.
