Adrien, none of the receivers mentioned have all the features which are desirable, but the 1400 in my view has the best combination in that price range. As you say, DPLIIx should be a must for playing 2 and 5 channel material on a 7.1 setup. Upconversion to component is a nice convenience which both the Denon and Yamaha models mentioned have. Automatic equalization is a big plus for the 1400. Internal bass management for SACDs or DVD-As is available on the HK630 and 525, but neither the Denons nor the Yamahas have it. Your choice.
