From my experience in this kinda situation 9times out of 10 it's drummers fault. Bashing hat and cymbals is'nt the best way how to get drums sounding good. Less metal, more drums - golden rule. Of course, if You are hitting drums properly, positioning is only about getting excellent sound. If not... positioning can help You eliminate some problems, but it wont be that 'aaahhh' sound.
You have good mics, so my advice is - treat the room (but not overdo this). Try lighter, sticks without plastic ends. Softer cymbals. You can even try to put a little piece of cloth on them. Or gaffa tape (last resort). Only then play with mics. Positioning IS king, but only after drums and room sounds good as possible. But first - play cymbals softer and drums harder. It's working, indeed! Good luck!
