Emu XL-7 & MP-7 User's Group

I was wondering...

Does anybody use any post-recording mastering products?  One of the 
main reasons that I purchased my XL-7 was that it sounded great 
right out of the box.  After messing around with EQ's and levels and 
compression with software studios, this was perfect for letting me 
concentrate on actually making MUSIC.  I've got my recording stuff 
all setup (going to an Audiophile 2496 w/ 24bit recording) and it 
sounds good, but I still want to be able to tweak the sound here and 
there, deepening the bass and stuff like that.  Are there any VST or 
DX plugins that I can use to give my recordings that professional 
sound?  The easier to use the better.  Thanks.
