Thought I would pay your system a visit after seeing your post to mine. Very nice. You must have the best theater room in the city! I moved my old MGIIIa's into a dedicated theater room last year and added Maggie center and surrounds.
I have a found the vandy 2wq sub works extremely well with the maggies. I have one on the audio only system with my 20.1s and one with the 3a's in the theater room. Sub works great with each application. How have you found the REL matches with the 20's for audio only?
