I have been researching speakers for about 2 months now. I am probably going to purchase the epic 60 but upgrade the center to the 150 and the sub to the 500. I am leaning towards denon for the reciever. My room is 22x12x10. Do I need the 3805 or will the 2805 be sufficient. Can anyone tell me what I will be missing if I go with the 2805. And last but not least, if anyone has a strong opinion on another reciever, I am opened to suggestions.
