Looking at the manuals for the 7500/7700 vs. the 755/770, the newer models state:

"Damping Factor: Greater than 400 from 10Hz to 400Hz"

While the older models state:

"Damping Factor: Greater than 850 from 10Hz to 400Hz"

This appears to be a significant change. Has something changed in the design to create this difference, or have the Outlaws decided to use a more stringent or different approach towards this measurement?

I just purchased an Axiom Audio Epic80-500 setup w/ two sets of QS8's. I ordered from their Factory Outlet and assumed I'd have to wait the 8 weeks that was posted for delivery. Well, after one week I received an email confirmation that my order has shipped. Now I need to get something to drive that setup, and I've been leaning towards the 990/7700. I had been following the 950/770 for some time, and knew the high damping factor was desireable. In researching to make my next purchase I noticed the discrepancy. Any thoughts?
