I am hoping that the shinier bulbs out there can help one a little dimmer like myself. So If I am running Pro Zero and simply turn off the Iron Audio does this affect depth in any way ? I want to run this machine to the max. wide open in a field. But I have some serious iron trash patches in there and it sounds like mother ship communication in ''Close Encounters of the third kind'', with all that iron tone. Also...... Notching out. Does notching out (eliminating) reduce depth or does it just make me miss that narrow specific metallic signature, as it should ? Is all of this based on the signal being cut out from being relayed to the speaker\headphones ? Thanks.
