OP says amp needs A&B out. Otherwise I would agree with Akg_ca on the Simaudio recommendation, having run the Arro's with the i-5. I currently run the Arros with a Magnum Dynalab MD-209, and it is far superior, but well out of the OP's price range. I think that the Magnum Dynalabs extra power has a lot to do with it, so I am thinking an i-3 with the Arro's would work quite well. But of course no A&B."
I'm pretty sure Sim makes the integrated amp portion of your Magnum Dynalab.
