I'm biased because I own a pair of the KAS's but I do love them. Deep bass, very seamless, top end crisp but not bright, airy, very smooth overall. I sold my Thiel CS-6's which were blown away by the KAS -- and I loved those Thiel speakers but had to spend a lot of time taming the brightness. Didn't notice any grain (could be that my ears are not as trained as some though) but they did put out a very wide soundstage in my prior listening room (I'm moving so they are in climate controlled storage right now) -- acoustics and placement have a big bearing on that.
