I'm hoping to buy a new rig sometime this summer and I would like to be able to compare the potential volume to the amp I have now. I play jazz but I feel that my Workingmsn's 12 is not quite loud enough for some of the situations I find myself in. The cabinets I'm looking at are the Euphonic Audio, Bergantino, and Epifani 112s as well as the three smaller Accugroove cabs. The amp will probably be the iAMP 350. Could anyone tell me how much more volume/headroom the high-end cabs will have as compared to the WM 12? I know the EA cab will be quite a bit louder than what I have now, but what about the others?
