hey milehigh....grew up in Applewood (Golden) area, lived for years in Evergreen enjoying the steaks at Keys on the Green and of course, Little Bear. I followed the 607 too, about ready to buy and went to my local Best Buy (Magnolia) to hear it. We started playing with the different set-ups and both liked the sound of the 707 better. It's got a better processing chip, 10 more watts, and THX certification which the bb guy summed up as little bit better specs all around. Most will probably say there isn't a whole lot of difference in the sound between the 607-707-807 but in that room, that day, I thought the 707 had a little more "weight" to it than the 607. Couldn't tell much diff between the 707 and the 807.....however, he was having trouble with the 807 because it wasn't installed in the rack properly, we didn't spend much time with it because the networking properties that set the 807 apart were not important to me. The bb guy was a Yamaha fan so he had to get the new 765 in the mix, the 707 blew it away. I made my decision and set my personal "buy" point at $599. A week later I happen to catch the newegg promo and bought at $569. Lovin' it! I don't know if Ultimate Electronics carries Onkyo, but do yourself a favor and spend the time to audition the 707. I'd watch the newegg site real close, bet they do some promo again, great outfit!
