I currently power an Aguilar GS212 with an SWR 350x. I really like the sound I get from the combo but I'm lacking headroom and at big gigs I just need more head. So, I'm considering the SWR Workingpro 700 because I like the SWR sound. However, it doesn't have a tube in the preamp like my 350x so I'm concerned it will sound a bit sterile. The Genz Benz shuttle 9.0 is so light AND it has a tube in the preamp. Any opinions on how these compare and how they would do driving my Aguilar? My GS212 is a 4ohm cab and rated at 600 watts. The GB puts out 900 at 4ohms and the SWR 700 at 4 ohms. Looks like I can get the SWR head for about $570 and the GB for $670. Opinions appreciated! Phil
