There may be no problem with your Bose system. I just have heard about problems with some and would hate to see you end up with something that doesn't work.

I love my 2500 and would recommend one in a second if I knew it would work for you. The big improvement with the 2600 is the HDMI connections and 480i to 720p upconversion that seems to be having some bugs from what I've read. You may not even need all the power that the 2500 has. There are many models of receivers that may work just as well for you and cost much less. I don't know enough about your speakers to be able to make a good recommendation for you. But there are other members here who do know much more than I. No doubt that they will chime in sooner or later. In the mean time, here is a good site to check out what Yamaha has to offer.
