Well first off, welcome to the board..
2) Listen to what you have first when the new equipment arrives.
3) Determine a budget.
4) What is your room layout?
5) What do you want to achieve too?
The Synergy line is a good mid priced, better than most, mid performance system too!
Yes, you can alsways go bigger and better from here... But that really is up to you on your dream wish of where your going?
Hope this helps!
You got 11 years out of the last system, do it right, and you might get 11+ years from here too!
