The M100s are without question the most bang for your buck speaker on the market. I've been listening to lots of high-end speakers and just love the value the M100s. Even had the chance to hear KEF blades and B&W 800 D3s last week which cost tens of thousands more. Those beasts perform better but nobody in their right mind would spend that kind of money after listening to a pair of M100s which cost 3k compared to 30k.
It's also worth noting that I took a B&W 702 s2 a few days ago and placed it next to a M100. With a little PEQ you could barely hear a difference. The 5k 702's had a slightly better sound stage but it was not noticeable to anyone else but me, the guy who spent the extra money on the 702s.
