I have a pair of Tympany IVA's, which I bought new at least 13 o14 years ago. They are wonderful, but...They are extremely sensitive to placement. When I have moved, it will take me one to two years or more to get them optimally positioned again! You have to crank them up fairly loud to get them to come alive, though I may be underpowered. I have an Eagle2A on the bottom, and an ARC D70MkII on top, (and an ARC SP10Mk11preamp), and a custom built crossover between preamp and amps. The better the equipment is, the better the sound. Of course, they visually dominate the room. The bass is better than other MG's I have heard, but I haven't heard any since the MG3.5, nor the MG20. I wonder if I would like the MG20's. Can they come alive at moderate volume? Is their bass as good? I would prefer to be able to listen at more moderate volume to preserve my hearing (wouldn't it be tragic if we loose some of our hearing?) They also need a great deal of power which would require me to reconfigure my amplification, which would cost a lot of money, and I would probably have to give up tubes on the tweeters. I believe the Tympany IVA's are the best of the Tympany series for an overall balanced sound. Good bass, very good highs, and a good midrange that requires volume to come alive. I have heard most of the Tympany models, and I like the IVA's the best. In my nearly quarter of a century owning Maggies, I've owned 2A's, 2B's, and 3's. When I bought the Tympany's I felt I had finally arrived. In many ways I still feel that way. So go for them!
