Just wondering if anyone here has ever returned their towers for an exchange? I have owned both the Sierra 2 and now the RAAL towers. And to be honest I am preferring the Sierra 2 with Rythmik sub over the towers. I have been playing with them for a week in every type of placement and changing from my SS to Tube set up. The Sierra 2 sounded better and was much easier to place in my room. I would hate to make Ascend mad but I almost feel like exchanging the speakers.
