Right now I have an SWR rig and some extra cash. Here's the rig: (1) SWR Interstellar Overdrive Preamp (1) SWR sm400s (500 watts @ 4 ohms bridged) (1) SWR Goliath III Jr. (2x10) (1) SWR Big Ben (1x18) Would it make more sense to add, lets say another 2x10's cabinet or trade the sm400s in for a higher powered power amp ? Suggestions? Right now I'm looking into used stuff just to save some cash if that makes a difference. Talk people 'cuz I know you're there.
