Hi Dave, I have had good success with a voicing iron that is quite hot, prop the hammers up with a voicing block, iron from 3 to 9 o'clock with quite firm down ward pressure. Deep needle with a single needle low on the shoulder on the low point of the cup, it will also open the sound quality, as well as brighten the tone. I know there is little perception of a cup, but I think you will know where to stab. Voicing up with needles in this area usually gives quite a tonal improvment as well as increasing brilliance. Ironing alone will increase brilliance, but will also increase percussion or impact noise! Hope this helps.
