Yes I did, haha!
For whatever it´s woth here are some impressions after a few minutes.
Black module + vocal switch down = bassy, too muffled, vocals not clear/prominent enough
Black module + vocal switch up = much better balanced, sometimes too much (something in between the switch configuration would be perfect imho)
Blue module + vocal switch down = less bassy, sweet spot so far, best balance
Blue module + vocal switch up = too shouty
I know these are some very quick impressions, but do you need much more to get the main idea? In most cases I don´t think so, especially when what the switch is doing is so so evident and in your face.
I like the vocal switch and that you can use it while listening but its just too much, better call it shoutswitch 
Blue module + vocal switch down could use a tiny bit more bass for my taste so ideally a module which is between the black and the blue one.
