(odd repeat posting of my previous post... how do you delete a post???)
I know it is somewhat sacrilege at this point to alter anything, but I have Ultrasone Proline 750's which are capable of very deep bass, and so tried out the subwoofer and "allow low freqs (only for BIG systems)" features. Here is my config chain file if you want to try it. Very deep bass comes through nicely for electronica - haven't taken it through its paces on other music yet.
