I used Rogue Magnum 120's for a while with my Maggie 1.6 and it was never enough for me in terms of volume. It did have a wonderful focus and depth. I could see where tubes are a good way to go with Maggies if you do not want too much volume otherwise it cost too much. BTW you may want to consider an Autoformer if you go with tubes, it will add volume and let you control the tightness of the bass, pretty fun and sounds good too.
As far as the edge, I believe the Maggie midrange has so much output it needs to be tamed with ficus trees or foam or whatever you have on hand.
