Thanks for the operational breakdown. Unfortunately, I can't tell any difference between that method and connecting an extra ground wire to the case of the pre-amp or to the RCA shield. Which matches your "really doesn't matter" point...
I was going to try a Jensen since they are "only" around $100. From their web page it seems the JT-11-BMCF would be the best bet or is that complete overkill?

The subs are great and seriously tactile at high volume with bass heavy music; I'm just hoping for something more precise at lower volumes. One improvement was from adding a sound isolating pad to separate them from the house foundation (which had various resonances that I'm sure displeased the neighbors).
But, I'm getting the feeling I perhaps should have spent the extra money to pick up some velo 18s that were for sale locally from porchecab or held out for some triad platinums...
