Thanks Charlie and gonk for the help in uderstanding the whole calibration of gear to reference levels. I think I kind of understood before but now it is a little more clear. I think this whole thread has helped me to become a little more clear on what I want to do as far as upgrading my system right now. I think that I am going to buy three 2200 and run them thru my Nad 752 for now and let the 752 run the rears. This will afford me the option to add a nice preamp and maybe two or three more 2200 in the future while greatly enhancing my current system now. Thanks again everyone for your helpfull comments.
