Hey Guys, looking for new towers and a center. Was able to audition the Martin Logan Motion 40 and B&W 683at Best Buy a couple of days ago. They both sounded worlds better than what I currently have but I preferred the Motion 40's over the 683's. The ML's tweeter sounded much more airy, lifelike, and had a better soundstage in my opinion. Diana Krall's voice just "floated". Those are the only speakers I've really had a chance to test drive so far. My question is, has anyone heard both the Motion 40's and the Salk Songtower SC's. Obviously the Songtower's have had some really awesome reviews and I understand you have a 30day trial, but I would probably order a custom finish and would lose the ability to return them. Any comments would be appreciated. Thanks!
