I read something on the difference from Nuforce. My current speakers(DCM Time Windows-the original) are inefficient(probably 82db per watt?), so they might qualify for upgrading to the 9.02's. I know that there are people out there that own both the 8.5's and the 9.02's. I was just hoping to avoid futher research and e-mails. I can't help my "Now Playing", as I was brought up on them.
