I owned the Arros. They cost less than the Sttafs, but like Lars said, I don't think it's fair to characterize one as inferior to the other. I agree with the others with regard to the Arros working well in a small room at moderate volume; they sound very good within their limitations. I've only heard the Sttaf briefly, but from my impressions I gather that the Sttaf is a little more warm/forgiving, whereas the Arro is a bit more articulate/involving.
