During the audition, it was an Eric Clapton dvd. I have heard this dvd on other systems, and it's clean.
The truth be known, I had ordered Klipsch from brandnames and never received them. I canceled the order. After I canceled the order, I auditioned B&W and Monitor Audio. This opened my eyes (and ears). Speakers have come a long way since the huge boxes of days gone by. It just don't take huge drivers to get quality sound. Heck, to my ears, the smaller drivers sound better. Even in the Klipsch Reference line.
