Has anybody listen to the jbl s312 hooked to good front end equipment.And how they compare in there price range.i heard them on a av amp in a sound room ,they sounded thin in the soundstage.But it would make a difference on the recording and they were not broken in.the sound was very clean,but like said not very strong front to the music. they may have promise with good gear.I would like some imput.thanks dennis
