I would also be interested in hearing about the differences between the Treo and the 3a Sigs. I own the 3A Sigs and find them to be very fine speakers. In what ways do the Treos fit between the 3A Sigs and the Quatros? Are the drivers better? Does the design of the cabinet make for better sound? When will they be available for audition at Vandersteen dealers? Is the 3A Sig being discontinued?
