For some reason, Denon always seems to be at the forefront with their features. Except when they are perfecting technologies. They took a while to come out with a universal DVD player because they wanted to make sure it had excellent bass management as well as solve the Chroma Bug issues, they succeeded with the excellent DVD-2900. So it goes without saying that they make some of the best pre-amps in the world because they are always the leader in new technologies with quality components. So I think using a Denon 2105 as a pre would be a great idea. The only problem is that it does not have balanced interconnects.
