I'm changing my rig around (buy my swr and eden!!! theyre for sale) and hopefully switching to a pre/power setup. But I need help! I'm stuck! Should I get the Sansamp RBI preamp or the BBE BMax (thats the non tube one btw, which is 300 less). They cost about the same, so I'm stumped on what to get, or should I get something else entirely? Any help would be great! Thanks.
