Talon Audio has to be the best I've heard of. A friend of mine blew the inside woofer of one of his Khorus speakers. He also had one of the bases damaged from shipping after buying them second hand. He called Talon. They overnighted the parts including two new bases, and flew a guy out the next day to repair the speakers in his home. All of this was done with no charge. They also upgraded his speakers cones to the current versions being shipped with the speakers. All of this for a second owner. I am amazed!
