This will be a long weekend for you, but you are all on the verge of entering ear candy heaven.
Ford - you absolutely MUST get yourself a sub. I checked the manual and it says "when a guys retires and his friends pony up cash for a set of Axioms he is required to purchase a sub as soon as humanly possible". It's not just me - the manual says says so. HSU, or my preference of SVS, will provide you with an additional facet in your HT experience that you can't appreciate if you have never had a good sub.
Denon 3803 plus Axioms plus HSU sub minus TV. Hmmm.... Not only is it impossible for me to solve that equation,
the "minus TV" part might be against the law. I'll defer to the opinion of Cap'n Pickard, as extensive legal research will be required here.
