I've heard the D1.2 set up really wide apart with direct toe in and a shallow seating position and was amazed with the sound. There was 1 time I got to listen to the D2.? and they were set up more conventionally in a listener triangle a few feet from the front wall and while I didn't mind them they didn't get me looking up the state of my 401k to see if I could afford them.
There was a couple year old pair of Raidho D5's on another hifi forum the seller started at $80k and didn't get anyone asking about them until he lowered the price down to $27k. That's a bit over 10% retail. I would suggest be sure they're what you want.
