Spectacular
I am not an audiophile, but definitely notice the clarity from these speakers. Spent quite a bit of time in the magnolia room bouncing between the Def Tech and B&W. The B&W were a close second, but price was the deal killer and actually I felt the tweeter clarity was slightly better on the Martins. Only draw back to the motion design is they are somewhat directionally sensitive and there is some difference in the sound depending on where you are physically positioned in relation to the speaker, not enough of an issue for for my taste though.

Stunning but underwhelming
These speakers are gorgeous. The high frequencies are stunning. They sound amazing for their size. I have a B&W 7.1 system in my living room. I added these two to my bedroom for music. I ended up exchanging them for Deftech Promonitor 1000s. You absolutely need a subwoofer with these in my opinion. Also, I feel like they favor the upper frequencies. They're amazing but don't integrate well with other speakers brands. When I had both rooms on and was in between these completely drowned out the living room. To me they sound bright. Overall I'm glad I went with the Deftechs. I do miss that tweeter though. The Deftechs can handle way more wattage by the way and cost less. The bass from the Deftechs is astounding.

Sleek bookshelf speaker.
I was not sure what kind of performance I would get from this compact bookshelf speaker. But I was pleasantly surprised by how full and clear the sound was. The black lacquer, curved design is very sleek. I really like how Martin Logan incorporated their high end, ribbon tweeter technology into this model. I will say that this speaker likes plenty of power. So don't be afraid to use a potent amplifier. Also, I would agree with others that have reviewed this speaker that it does need several hours of break in time. After which you will truly hear how good this speaker really sounds. The more I listened, the more I enjoyed the fullness and clarity of these speakers.
