I had this question as well.... Did some research. Presently I own a DRRI. LOVE LOVE LOVE It. Cut the bright cap and put in an Eminence Cannabis Rex. Not needing anymore power. 22w does the trick for bedroom, garage jams, small clubs, and small outdoor venues. Even at 3, I get great cleans with minimal breakup and it cuts through the mix very well. Takes pedals incredibly well. That being said, If I needed more power, I'd upgrade to a 68 vibrolux. 35 watts with two tens is very very loud.
