Stand alone DACs are usually for those who already have an amp for their passive speakers, and act as a minimal pre-amp. Many stand alone DACs can be a fine source for active speakers, tho. I hear very nice things for the JBL LSR305s for the price if that's the size speaker you're interested in, or you can go to their best in their big brother, the JBL M2. Are you looking for a desktop setup or something more for a larger room? Is this for mixing/recording or just playback? Budget? Music source(s)?
