Well, they are absolutely not bass-shy, that's for sure. Have listened to them today both balanced and single-ended on the 307A, Balancing Act, BUDA, Zana, B22, HD2, Luxman, SDS-XLR, Woo 22 and some others -- and my ears are profoundly content. My only caveat: some songs on some sources suggest the slightest shade of sibilance.
