So, after a lot of research in the TB archives and elsewhere on the Web, and advice from numerous people, I called Jack Read this morning and ordered a Stewart World 1.6 power amp. This will be my first pre/power set-up. I'll be using a Sansamp RBI with the Stewart, which I'll run bridged/mono into my SWR Goliath Sr. I can't wait to hear this thing roar! This experience reminded me once again how great Talkbass is. I hit up various people via PM for advice and counsel, and everyone responded really quickly and in great detail about power amps and their set-ups. It really helped me decide. So, many thanks to Bob Lee (QSC), rockstarbassist, atldeadhead, bikeplate, Joshua, and roscoe5.. I really appreciate your help. I'll post a review once I get it all set up.
