Sbank and the others are right. UNLESS YOU HEAR A BIG IMPROVEMENT never change. There are very few systems that cannot be improved 10% to 50% by careful tuning. Most people change their systems before they have gotten the most out of them. Spend the money [probably a lot less] on improving what you have and don't change until you have recognized a flaw in your system that you cannot live with. AND FOR HEAVENS SAKE DON'T CHOOSE YOUR EQUIPMENT BY ASKING OTHER PEOPLE.
