What do you currently have? B&W does have a rep for voicing their speakers tipped up in the top end. Consider your room acoustics and type of music you listen to.
Pairing advice
After a long search I have my speaker choice down to either the Aerial 5t or B&W 705s2. Leaning toward the 5t as they sound a little more mellow. I love detail but not brightness which I felt the 705s leaned to. My problem is I don't have any dealers within 500 miles that carry either speaker with my Moon 340i integrated and Moon cd transport. Has anyone heard either or these speakers paired with Moon products that could give me at least some idea of how they pair?
