I'll start by saying I have read some/most of the threads concerning power amps and the "read this first" thread but nothing really answers my particular needs. First I'll give my scenario. I play mostly at home but would like something that is flexible enough to do some small venue bar scene gigs. Currently I have an SWR Studio 220 connected to an 8ohm Son of Bertha 15" cabinet. I'm running a Tech21 SABDDI into the power amp in and just using the SWR head as a power amp. It didn't sound particularly good before and now it sounds OK. The question is what would be a good PA to pair with this setup and would it make it sound a lot better. Most of the threads involve higher priced items and even though I have GAS I don't have the money ( Kids are currently using that ). So for < $500 can I get anything that would sound good. I use a Lakland DJ so it shouldn't be too hard to make it sound nice. Would something like a QSC RMX 850 do the job?
