I downsized from a AC30C2 to the AC15HW1X and I would consider it a step up. Out of the box I powered it up and to be honest, I thought at first it was a little too bright and harsh. After playing for a couple of hours and tweaking the dials, the amp sweetened right up. Now I'm lovin it. Sam Ash shipped promptly and I received the amp a day earlier than anticipated.
