If we were changing amps and players all the time during the audition, it would make sense but we're using the same stuff unchanged, same volume level, even without moving the speaker stands. We sat in the same exact spot and ran the same exact track. So the only thing that could be faulty if any, is the 706 itself. But it didn't exhibit any obvious mechanical fault or flaw so if you believe in breaking in new speakers, that could be it. Believe me, I very much wanted to save $200 since I care not about the added cosmetics on the 806. The speakers are going to my office system anyway and will be paired with the Panny XR57.
Since I've read your response I've called the dealer back and said I may want to exchange the 806 back for a 706 but I'll decide after another audition. Luckily he's willing to let me choose the speakers and I'm gonna do it this Sunday. I'll let you know...
On a second note, my buddy went and bought the whole 5.1 set with the 700 floorstanders and all so we auditioned that setup as well. Their character is the same as the 706, somewhat a bit flat and not refined enough to be high end. So I really don't believe it's a problem with break in period. But let's see, he wanted to change them all to the 800's.
