I just called Emotiva, and all of their products have built-in surge protectors, power conditioners etc. etc. The technical guru at Emotiva said that using two separate circuits is a good way to go but I have to watch that I don't get a ground loop. I'm plugging the amp into one of the plugs of my 20 amp circuit and a surge protector into the other plug for my TV, then I'm going to plug another surge protector into the other outlet for the rest of my components that don't draw much. Now I just have to figure out what to do about my subwoofer. I know for sure I'm not plugging it directly into the wall.
My Denon would draw the most out of the rest of my equipment.
