The AVM20 is very upgradeable and you may not be interested in 7.1 now but if you experince it you may change your mind. I know I did. The AVM20 is a more versatile piece and with the v2.xx you get THX Ultra2 which is very nice indeed. The AVM2 is still a nice piece but the AVM20 will not leave you wondering if you should have gone with a better unit.
