I own the Mini2 and drive them with Pass XA160.5. These Magicos do need a lot of good, clean power and I think you have that. I have heard the V2 and V3. I did not like the V3 as much as the Mini2 or the V2, but I really think it was the set up at the dealership so they were not demonstrated to their potential.
I found the Mini2 lacking in bass impact and extension at the dealerships, but that was greatly improved in my own room after finding the right spot in my room and also with recent improvements in isolation to my front end. Bass was always very articulate and detailed, but now impact and extension are very good also. Magico does bass very well, IMO. For me it's about quality, not quantity, especially with the kind of music I love (cello, piano). The V3 should be even better in this area if the room/listener/speaker relationship is right.
I did find the V3 less coherent compared to the V2, Mini2 and especially the Q3 and Q5. Perhaps it is because of the physical separation between the mid and bass drivers. I don't know, but this is the weakness of the V3, IMO. I would want to audition a pair in my system for a few days to be sure.
The used prices are very good now on the older wood enclosure Magicos. I think it is a great time to buy. I listen mostly to smaller scale classical and jazz in a small room, and could not be happier with the Mini2.
If you've heard the Mini2, why not consider a pair of those at used prices? If you want bigger, the V3's could be the way to go.
