I wouldn't hold my breath while waiting for a reply from ATI. Take a look at the post on the "naked pictures" of the 7500 and I think you will conclude the ATI and Outlaw are the same. The 7500/7700 are great rebadged ATI amps and Outlaw offers the 30 day return policy and a 5 year warranty. You won't really loose anything except shipping if you don't like the 7500/7700. If a great deal on a 2005 had not come up (two days before Outlaw announced the 7500/7700!!) I would have purchased the 7500 because I was confident it was to be made by ATI based upon comments I got from Outlaw. The info since the announcement confirms the ATI 2000 series is the same as the 7500/7700.

I went from a Pioneer Elite receiver (much like your Denon) to the 990/2005 and I am very pleased. IMO, if you replace your Denon 3805 with the 990/7500 you will also see a big improvement.
