Like I said in your other post, there's a couple of things to weigh up. Diezel would know their own amps best. AMT would be doing their best to work out how to get the sound by available schematics and by ear. If I was in your position and had to have a stab in the dark, I would get the Diezel if it wasn't too much, check to see if they have a return policy and if it sucks, return it. Or if there's a return policy on both, you could even buy both, compare them and return the one you don't like (which some people will think isn't very nice but it's an idea).
