What Speakers For Kinki Studios EX-M1+?

Too late now, but you've gone about it exactly backwards.

I have paired Monitor Audio Gold 300 with EX-M1+

Those both look amazing. I’ll check them out!

i second the Rosso Elba 2.
if you like the focal sound.

I would consider the Rosso Fiorentino Elba 2. Not as many reviews as others, but you won't find many negative comments either. 

Maybe a few more details...

I’m considering the Monitor Audio Silver 300 or the Dynaudio Evoke 30. I also like the Klipsch Forte 3 and Tekton Double impact for a more lively sound. But those are quite big and may dominate the room. 

I listen to all types of music except classical.
