I just got my Airmotiv 4's today and wow they are awesome. Very crisp highs, great detail across the entire range and very tight bass. I was worried that the 4.5" drivers wouldn't have enough bass, but it is more than plenty for a desktop setup. I have X Series interconnects on the way as well as the ASM base, so I'm sure they'll sound even better. Right now I have them temporarily on the Audioengine DS1 stands, so the tilt angle is right, but the stand is far too small heh. I highly recommend these to anyone looking for a $300 desktop 2.0 setup. The sound quality compares well to the Energy RC70 setup I have in the living room (of course they lack the raw output power and bass of the RC70's, but I'm really loving treble of the AMT tweeter).
