I can back up Mnnc on his statements regarding the AVR7120. I love this receiver. The build quality and power availabilty are outstanding. I have been thoroughly enjoying my receiver now for a couple of weeks and have no regrets about my purchase. Also of note, the Boston Acoustics service department is extremely helpful if any problems/support is needed. One of their technicians mentioned to me that they pride themselves on their service department and will do anything possible to help fix or replace a malfunctioning unit regardless of warranty terms. I have not had the opportunity to play with the 7200, but if it is anything like the 7120 you will not be dissapointed. Do keep in mind that there are several posts on here regarding other amp manufacturers that may be useful to your future purchase.
Good Luck
