I realize these two are of a slightly different price-class, but on a general note, taking price/performance into consideration which would you say is the better purchase? I've currently got an AZ1 on order as I have always been very happy with my Yamaha products in the past, and as I'm not really too bothered about the THX Ultra 2 certification I thought I might as well. However, reading more and more specs on both of the amps I've found a few features the Denon has that I would really like. Specifically the video conversion, real EX, more power and well, it seems to be the favored make amongst true HT fanatics. Should I consider cancelling my AZ1 and order a Denon instead? Or do you not think the extra features/power is worth the extra grand? Waiting for both to be in-shop to demo them myself isn't really an option as I need the order placed now to get one asap.
