What should I run my Eleven rack through?

[DannDMann]

I picked up an Eleven Rack to try one out again. After 2 weeks I have liked the sounds I am getting when I record into the ProTools that came with it. My issue is I have tried to run it straight through my PA (Admittedly it's a fairly cheap one) and also through a Line 6 Spider Valve amp and didn't like how it sounded. With the amp I tried it straight in the front, in the fx loop and also just in the fx return with varying results but not crazy about any. My question is for those who don't just run this through a computer (or front of house when playing live) what do you run your Eleven Rack through and get good results? Sorry, I know this has probably been asked before but any advice I'd appreciate. - Dann
