I think all of those options will be timbre-matched, but I would follow 500's advice and purchase the VP150 over the VP100. I love the VP150, and I think you would regret not shelling out the extra money for it. If you are looking to cut corners, I think you would probably be better off skimping on the surrounds, and going with the QS4's rather than the QS8's. From what I hear, they are pretty similar in performance.
