My main band is planning on moving to in ear monitors and to remove backline from the stage to reduce on-stage volume. I think I've decided upon the Presonus Studio Channel as a preamp. I'm thinking about selling my bass rig (Ampeg SVT 4Pro, BXT 115, BXT 410) and downsizing (I still need something for when I gig with other bands). I'm thinking about getting either an Aguilar 212 or Genz Benz 212 and some sort of 210. I would need a power amp to push the cabs, but I'm really not sure where to start. Are there any power amps that you guys would recommend? I would prefer something on the lightweight side of things. Also, I would like something that has the has the versatility to run just the 212 or the 212 and 210 at the correct ohms. Thanks for your help.
