I think your current equipment and room sound perfect for Maggies. With the amp and subs that you have you could go with Maggie 1.6qr's even, and be very, very happy. I have heard Bi-amping can be helpful, but found that more powerful amps seem to have a similar, but sonically more coherent effect, your VTL will work beautifully. I just sold some 3.6R's and miss them terribly. The only other speaker that I have heard that I like nearly as well as Maggies are the Innersound speakers. But you know, it's all so subjective anyway.
