The M3si is a very special speaker and your going to have a hard time finding a suitable replacement I'm sorry to say. I wish I had a suggestion, but I'm on the hunt myself. Another issue is cost, your going to have to spend some serious money to find something in 2020 that's full range and has the same HUGE soundstage. Personally, I'd keep them or if your on the East Coast, sell them to me. :)
Are there any current high end dipole speakers (dynamic)?
Looking to upgrade my decades old system which includes Mirage M3si. No they ain't perfect, but the speakers disappear and that kind of sound is very appealing. Electrostatics (bipoles?)aren't the same (though when my mirage's die, I'll probably get maggies).
Thanks for your time.
