Steve:
I have owned Piega C40's in the past and loved them, however they were a little light on the bass, but they had a midrange and high end to kill for. My fear about the Master Line Source 2's is that with those 4 coaxial drivers, the speakers might be very bright, however I have never heard them. It would be great if you could hear them first, especially if you have a difficult room.They sure look nice, however they are quite tall. Good Luck! Sam
