Wow, I'm 20 as well...

I also have the M22's and 884 like Josh does. Both wonderful pieces of equipment (my only complaint is about the lack of preouts as well). I have the STF-2 complementing the 22's and it is a more than ideal match. I don't think you will have any reservations about going with the STF-2 although i would like to have at least tried the SVS. From the review that Spiff did about the differences between the SVS and Hsu subs I'm glad I went the way I went. I like really tight bass. I think this is a revolution for 20 somethings to make a resurgence in the semi-audiophile society.
