A Few of you have mentioned that these are older models, and even mentioed how pricey Arc is with repairs, or even the colors, "Child Please" ....Sometimes Older is Better ? These amps have been around awhile and for , Good Reason. Built solid, power is under-rated vs over-rated as so many these days are. And unlike todays amps that so often are madeas cheap as possible, when something does go wrong it's not cost effective to even think about repairs, these Amps are repairable. WHY, because they are worth repairing . OH and the people that make them, also repair them, but most importantly they're made in the U.S.A. ~~~RBU~~~/SIZE]
