My Clarus went belly up last week when my son plugged the speaker lead into my mixer (ouch). The mixer was fine, but the Clarus took one for the team. I sent it back to AI with a note, hoping that it wouldn't be too expensive and wouldn't take too long to get it back. Less than a week after leaving it with Fedex Ground, it has showed up at my door with a clean bill of health, new output transistors, and a no charge invoice. I am sure we are way past any normal waranty period. All I can say is wow! I guess that series III Focus 2 just jumped up to the top of my GAS list. Thanks AI.
