thinking about outlaw's 5 monos with the marantz, but given i am relatively new to separates i was hoping someone smarter than me could tell me if this is a mistake? Also, i have read that HDMI 2.0a is important but i dont see the 2.0a or UHD designation for the 7704, am i missing it? is it there? Should i care if it isnt there? thank you for your help and suggestions. by the way, the room is bigger (25ft by 18ft) and i am using all vandersteen speakers (2ce sigs, the reference center).
