The only problem is upgradeitis. I would say either only get one of them now, or else spend the extra $100 and get the VP150 and QS8. Upgradeitis sucks, but if you have the best, it is unlikely you will have to deal with it as much. If you didnt go the best on one of them, a few months from now, you will likely be on this forum wondering if you should have went with the bigger speaker.
