I was in my local Circuit City yesterday and noticed that they had this as an open box - I know there has been problems with the ticking in the rears and reading certain DD encoded movies. I don't really care about the few movies but I am concerenced about the ticking - any way to know if this particular receiver could be affected - date of mfg? Or should I just buy a new one - I think I have seen that someone has gotten this receiver from J&R for 730 - shipped (can anyone confirm this - and if so - operator #). Or should I spend the money on something else? I currently have definitive technology speakers (home theater pro monitor 100's and the powered sub that goes with this system). Thanks in Advance.
