Of all the 8 nozzles in my filter sets the golden are the only ones with some filter screen in them ... looks like some plastic mesh. Like the black nozzles they don't have a vent hole (> max. bass) and on my sets their filter material blocks out a lot of the treble and air and drastically shrinks the soundstage. Makes me wonder why they show up right below the blue nozzles on the IMR - Bass/Lower Stage Filter chart.I also tried to use my DM with gold lower blue upper filters, and the bass on that setup is enormous, way above even New Aten levels. But overall sound becomes very muffled to me.
