Vandersteen 3A Sigs vs Klipsch Forte III

I'd like to get input on a comparison of both of these speakers. I have not heard them. No dealers in my area. I realize it may be an apples to oranges match up to many but want to hear the pros and cons of both. Haters welcome!!  I'll be driving them with a Mac 6200 integrated. 75w into 8 ohms and 100w into 4 ohms. Room is 27x18x10h. I listen to all music. Some vinyl. Appreciate moderate base, clarity in vocals, imaging, and like the speakers to "disappear".  Thoughts?
