A lot depends on your speakers. If they are fairly efficient, over 90db, then 100 watts is more than enough.
Try the biamping vs either amp alone. You may find that biamping is more difficult with lessor results. I've always had problems keeping the gain equal between amps (ie the tube amp may be louder at low volumes but as volume increases the solid state amp may gain more quickly and overpower the tubes?).
Try it!
