For the record I think you can never have too much power. I am considering the benefits of tubes on the stats vs. SS. Either way it will be killer, but I could sell the vk-500 and get into a good tube without spending any more money. Even though the panels are the same on the Vista and Vantage the panel will sound better on the Vantage because the amp is only running the panel. And from what I hear (sorry for starting a sentence with and) the lower-mid bass is better on the Vantage due to a higher cross over point.
Also for the record, this is one of the best problems I have ever had .
