I had a couple of sessions with KEF, and I own Mikros 90. While I am not sure I would pay 300 for ML, I certainly wouldn't pay 300 for KEF, even at 99 I would be very hesitated. I have stated before, I have the same opinion regarding KEF M500, that is their emphasis on sound signature and the realization of that in the end product is just simple not on the same level. KEF sounds very good to a degree, it is something pleasing yet extremely boring, like all the "fun", "midfi" product.
As for the soundstage, Mikros 90 does it with so much elasticity in regard to different recordings, I can hardly give the edge to KEF here. It's like what they say about cans that have a big soundstage sometimes don't convey intimacy well. It could be a very tricky thing.
Yup, we all hear things differently.
