I'm using a hybrid on top and a SS amp on the bottom of my Vmps Rm 40's. Many people will tell you that at least with planar/electrostats that some tube magic on top can be magic. They were right!
I think the main advantage is to take the best qualities of two amps and use them there as I have. Another benefit however is reducing the amount of crossover components you're using. In the end experiementation is key. With our VS's I don't know as I've not heard them. You could also try various tube preamps. Please remember different tube preamps will sound widely different. Some not very euphonic like Audio Research to somewhat more, Conrad Johnson, to syrupy.
Biamping in my experience in my system has been the best way to go. If you haven't owned any tube gear it's a must try. A hybrid amp like the Van Alstine Fetvalves are excellent. The Blue Circle I had also was an outstanding amp, although quite expensive for the money. On the bass using this Rotel 991 is excellent. The bass quality is outstanding and I'm picky in that department. For under 500 bucks there's a few amps that will work well for the bass.
Best of luck and have fun!
