Geithain doesn’t have a room at the Munich show, they have an open space exhibit. You can look and ask questions, but not listen.
Not true
Claus Bücher had a room where you could listen to 3 Geithain models
901 and the new MO1 MK2 included.
I owned the MO2 in the past and heard the RL901 a couple of times. I also had the KH120 and Genelec 8030. I visited the Geithain factory some years ago when there were totally unknown in the HIFI scene yet.
My impressions so far. All those studio speakers sound incredible similar no matter what size you choose (within in the same range of the manufacturer) The tiny MO2 with a sub sounded very very similar the 901. For that reason Claus did the demo in Munich. People sometimes could not beliebe those small speakers very really plugged in.
Same is true for Genelec. There is not a huge difference between lets say 8020, 8030 and 8040. Or KH80 and KH 120 when using a sub.
I would choose the speaker based on what music you listen to
1) Classical music, Jazz, Acoustic music: "Real instruments" Geithain. The founder of Geithain is a big classical fan and exactly knows how example an organ should sound like
2) I have not directly compared Geithain and Neumann. But I think Geithain is a bit more fun to listen too. Neumann maybe a bit more analytical
3) Genelec (80XX series) Thats the best one if you want to listen to a broad range of music. I think Rock music sounds way better on those than on the other speakers. Also modern "dance" music sounds better on the Genelec. I have compared the Genelec and Neumann directly next to each other in my room.
Geithain is mainly selling directly to German radio/TV stations. This is the area where there came from originally.
None of those speakers are really "better" than the others. They are all totally fascinating (for different reasons). I never heard the coaxial Genelecs. Might be perfect for me. But way too expensive.
