Few more thoughts now that I've had them for a few days. The imaging and seperation are extremely good, that along with their bass are the GS-1000s main strenghts. Their next best asset is their detail retrival which I think is probably unparalled in the $1k and under price range. The bass is also very good, it has the immediacy and snap of the hp1000 bass and goes pretty deep. I have noticed though that the treble can get a bit "tinny" and almost harsh at louder listening levels. It does seem to be pretty recording dependent, but it is more of an issue at higher listening levels. The GS-1000 do have a bit of a midrange deficiency, in particular the upper midrange isn't as prevelant as it is in the RS-1s. In my mind instead of having too much midrange bloom like the RS-1s these are kind of the opposite as they fall just short of having enough.
