Glory,
I heard the Magico V2 a very long time ago. I was impressed at the time. I think this is the sweet-spot in their line and I'm not a big fan of the aluminum-enclosure speakers even though they get a lot of good press. I have heard systems at CES that the reviewers raved about which I thouhgt were excriutiatingly brigth and just horrible...one of them was the aluminum M6 or 7 (their original big aluminum speaker).
The V2 was very smooth, relaxed but very detailed and coherent. A very good speaker. To me the MMMicro-1 is more open and neutral sounding without sounding analytical.
I have heard the Magico M-1's 2-way. As far as 2-ways go, 25K or 2.5K for the MMM-1....that only takes a second of thought. I would use the difference in money in the front end.
I like full range speakers...but I would be a little cautious in using a sub with the MMM-1. My concern is screwing up some of the balance and qualities of MMM-1.
I'm not a big fan of subs. Better to get a fully integrated design as "all of the parts are meant to fit together".
The MM-1 excells at upper bass and mid-bass but don't do low bass well as they are not designed for that.
All that said, the MMM-1 is an exceptional speaker and withing it's design range I would not chose another 2-way. AND, you would have to spend a lot of money to get a three-way with the level of performance in the mid/treble.
Have fun,
andrew
