"More decibels?"
Gooseman, most certainly. I have the setup Pat mentions (he was the one that told me what to tell the dealer), and it GOES!!! And yes, most definitely the decibel level is, shall we say, significantly increased! I liken it to an offshore powerboat. You might even be safe going to 135 mains from what I've seen. I've thought about this, but am fine with the way things are now, so haven't felt the need.
