I've had the pleasure of doing business with Klaus at Odyssey and it's always been a pleasure. When I was having trouble finding something that would drive some modded Magnepan speakers someone mentioned Klaus so I called him. Apparently others had already had the same issue and he gave me several options with various costs. I chose some Kismet in Stratos cases for an absolute fantastic price and he guaranteed that they would have no problem driving the Maggie's. When I heard of the parts he had planned to use being sourced from Symphonic Line, I couldn't refuse. And I wasn't disappointed. Everything I was missing from the system came to life after trying several amp and preamp combos. Since the initial purchase I've had an issue that Klaus fixed with no problem and no cost to me. I've also sent them in for some upgrades and was very happy when they were returned. I truly believe some people may shy away from his products because of the low cost but his amps compete with equipment costing 2 and 3 times the price. I have talked to Klaus recently and there are some new plans in the works for a design that sounds very interesting. Many years I've known the man and never have I had nothing but pleasant and informative conversations.
