No. I had a Stratos amp, a Tempest preamp and a Candela preamp. Two of them developed either a hum or spurious noise. I could not get them fixed correctly by the owner. After two years of back and forth shipping to Odyssey Klaus eventually bought them back at a big loss to me. He stated I had bad AC in my home. Never again. By the way, he lended me a Symphonic Line integrated while I waited for my equipment. It worked beautifully and it was very used.
Your first time posting here??? Interesting.
