I own the 3806 myself and if you were located in Europe I would say go ahead with it. But it has come to my understanding that the same receiver in the States is sold without the upscaling features which to me is quite important. The 3806 has better amplification and better auto room equalization. On the other hand the 2600 has the upscaling and both lack iLink I/O. Which one is better will depend on your specific needs, both are good choices and you can't go wrong with either one.
