I am seriously considering selling my schroeder stuff and getting another wizzy so that I have a pair of them. To do this, however, I would need an amp that would run at two ohms reliably for 3hrs or more. I am considering both integrated amps and poweramps at this point. I dont want to spend over $1000 and would like to get something pre-owned if possible. I would like to have the amp to be at least 500w and not be excessively heavy. I am would prefer more of a clean, (somewhat warm but not muddy) SS tone, but not sterile. The wizzys are already very clear which I love, but I do want some warmth. amps that I am considering: iamp 800/500 - maybe too much $? eden gk - any do 2ohms? stew 1.2 poweramp or similar. others? the most important thing is that it can run two ohms without me worrying about whether its going to shutdown on me during a gig. thanks for your suggestions!
