Im just looking to get a good surround is system for movies and music. I did some research and found out that theses components when bought new were about $10.000. I just came across this for package deal for $4000.00. The issue that i have is that the speakers are 5 yrs old and the rotel equipment is 2 yrs old. Is this a good idea to buy a system that is this old? Any advice?? Is this a deal or no deal situation?? Thank you for your time.
