I have both SSI's and Songbirds. If you have a sub and stands the SSI's will be a great start into the Salk family, but if you want a step up I'd go with Songbirds if you can swing it. As Richard said, SSI's have the same voicing as the ST's, but without the bass. You will get similar bass output from the Songbirds as ST's...they just won't go as low, and, as ricardojoa points out, you don't need stands. And yes, IMO they image better than my ST's did.
