Simple, you have three choices...
1. Brand new 3A Sigs. This allows you to spend the rest on the front end where it's better spent.
2. 3A Sigs with Subs. A significant improvement, but maybe not to your taste.
3. Vandersteen Quatros for $6500. They're essentially 3A Sigs with the 2WQ subs integrated into the speakers. It's as close to a 5A as you can get without spending the $10K extra to get the actual 5As. You should see them in the stores this year.
Good Luck!
