hello everyone, i bought these stands yesterday for my ma br2's, what a difference, treble is clearer, bass is more tuneful, the midrange is sharper more cohesive if you like. they just do their job really well and are a breeze to set up. i cannot comment on other makes like the atacamas but i would imagine they do the job equally well but for anyone in the market for new stands, give them a go. they look good too.
