Paid $250 for the KEF M500 and thought they were worth $80. Paid $80 for the Mikros 90 and thought they were well worth the MSRP of $300. Just sold the M500 and will use the money to fund a cable upgrade for the Martin Logans. Go figure.
I listen mostly to period, classical, jazz, world, pop, country, older rock, show music, funk, big band, techno, electronic, trance, etc. The Mikros 90 do justice to all these genres and they "do it" for me, Nirvana-wise--although I usually would rather "find" myself than "lose" myself in the music. : ) I prefer balance, extension, high resolution and "uber" detail retrieval.
My decided MLM90 bias is no secret and YMMV.
Can you get ahold of a pair of the Mikros 90 for audition?
