Hank,
Glad to hear that the G70 is working out for you.

You have a pair of the Sona 41's?
I've been interested in the Barbettas, especially the Sona 41. I've never heard the Barbetta's myself, but I have heard the Bose and like what I hear.

To your ears...
Q1, What are the differences, or pros/cons of the 41's compared to the Bose?
Q2, Is there a significant change when using 1 Barbetta instead of 2 (other than volume/sound pressure)?
