I am looking to upgrade my Sony STRDB1080 to one of the current Denon amps. One of the reasons for doing this is to get an amp that offers component switching, but I would also like to get a bit of improvement in the audio quality, even though I am happy with the Sony in this regard. I am guessing that I should be looking at the Denon 2105 as a minimum, or preferably the 2805. Does this sound about right? Is the component switching good quality on these models?
