I am building a home theater in my basement. I am using paradigm monitor 7 speakers, Mitsubishi WS-55511 HD television, Toshiba Progressive Scan DVD Player, Direct TV, and a Sony Mega CD/DVD/SACD player. I recently purchased the Denon 3803 on sale for $740.00. I am wondering if it would be worth the extra %500.00 to upgrade to the Denon AVR 3805 (Tweeter has the upgrade policy). Any help appreciated.
