I have a EBS HD350.I use it with two 4 ohm Avatar 1-12" cabs. Love the way it sounds! But sometimes I wish I had a little more power. The next model up is much more expensive, so I was thinking about getting a separate power amp for the times when i play louder gigs. I don't know much about this sort of thing,class C or D, getting a stereo amp and bridge it, or leave in stereo and use one side for each cab. Or get a mono poweramp ( they seem to be hard to find). I don't really want to get a heavy beast of a poweramp. Small and light is good for me. I have a Eden WT550 that puts out about 750 (I guess) into 2 ohms, which is what I got, and that totally does the trick. But on the Eden I catch myself fiddling with the knobs too much.I am always tempted to try to improve the settings. On the EBS I can just set it and not touch it all night. So can I get some input from you guys about how I can best up the power with the EBS as a preamp?
