I haver not heard the Magtech, but I'd be surprised if it was lean in the bass at all. The ESL amp I did hear however sounded cool, as opposed to lean. It didn't lack bass so much as sounding analytical. Not harsh, but close to the older ARC amps.
Sorry I can't help you with this specific model.

Erik
