I saw a post a while back that linked to http://authspot.com/thoughts/dmg-01-bass-mod/
Basically he suggests removing 2 capacitors from the board to increase the bass output. Well I never heard much from the community after this post and I wanted to try it out and see how it sounded.
Had some spare time last night to try it out as well as capture the results in an mp3 so you can judge for yourself if it is worth it.
Posted both the what I did and the results on my blog. Here are the links to the articles:

I'll be happy to try out anything people suggest as well. Didn't have as much time as I would have liked to mess around with this.
