When I had the 1.6 I made it a point to passively, vertically biamp them. It was a nice improvement. I am not into DIY or modding speakers, so this was a way to juice the performance. On an MMG I would suspect you will hear differences, of course mainly in the quality of the mids and highs. You should detect more "air", deeper soundstage and better clarity. Not in "boatloads", but maybe in "spades".
Some state that passive biamping is of little effect, while others say it's very worthwhile. There was to my ear a very noticeable change to the speaker's performance in my experience. Having used passive speakers with external Xovers (reviewed the Legacy Audio Helix), I can see where a modded Maggie would be considered even more enhanced.
Over time I experimented with more stout amplification and bi-wiring. I found that having a more robust amp and bi-wiring can yield even better results than using lesser amps and biamping. You owe it to yourself to secure possibly an older, well respected amp with some braun (i.e. doubles down into 4 Ohms, and maybe at least 150wpc at 8 Ohms) and see what you think. My guess is that you would be very surprised at the difference in sound of such an amp bi-wired versus the four channels of a receiver. :)
