My one suggestion on the Q4 and Q8 is to switch the soup cans from Chunky to a broth. You will get a clearer, more transparent sound, with much less muddiness...as if a veil was lifted over the speakers!
Haha. Classic. :-)
I think that the "Organics" can would provide a much more "organic" un-colored, non-hormone sound sound that the Campbell can.
