Very interesting. It sounds very familiar to an issue I had and could never isolate. I had a Magnepan 1.6, Odyssey Stratos Stereo Plus, and a couple different preamps. When I would start a listening session, often one speaker would cutout for short amounts of time, which drove me crazy. After a while things would settle in and the problem would go away. No amount of troubleshooting revealed the cause. It never happened to the new owner of the Magnepans, and it never happened with the Odysseys again. I just wrote it down to synergy weirdness. Other than that, the Maggies and the Stratos loved each other. Strange that it happened to another Odyssey/Magnepan combo.
