hehe yeah i have had the control 5's for about 10 years they are fantastic!
im using a Crown powertech 3 fully rebuilt and calibrated by stan at surry amps, it is amazingly good!, you hit the nail on the head with your reference to the brand, the macrotech stuff is awesome too. such a quality brand. the amp i have at home (the powertech 3) is a club amp, (rack mount) and i used to use it for my illegal events years ago, never let us down and always did what it needed to.. i do love Crown.
