I have had Odyssey equipment too, as stated earlier. Yes I had a Stratos, Tempest and Candela and not the Khartago. I had hum and spurious noise issues over many many months. When I spoke to Klaus...(when I could get ahold of him) he was at first courteous, but as time went on he was very condescending. As I returned equipment to him, he took months to repair items, and returned them to me, only to find they were not fixed. I spent thousands of dollars of what I considered later pure audio junk and bought from a guy who really did not take the time to fix the various problems. In fact on his forum on audiocircle.com anyone with a simple search one can find all the problems I had mentioned as experienced by other buyers. I would have thought after all these years since then he would treat his customers better (I know he has adoring fans) but I just got a message from a customer a month back who had the very same issues with a new piece and he stated Klaus DID NOT want to give him a full refund on new gear. He had to fight to get his refund. Anyone is free to purchase gear from Odyssey, but I think it is fair to give balanced opinions with both positive and negative experience for all potential audiophiles to look over before they make a purchase.
