I don't know Tvad, but I'm glad you did cuz I've enjoyed the heck out of it since you sold it to me. I think it will arrive Tuesday with the new update. I'm very curious to see what the new design has to offer, but I'll admit I've been a little nervous because I really had little to nitpick with the amp to begin with. If it hadn't been for the 300 series owners and Kevin raving about the differences I would have never really considered it. We'll see...
