In all seriousness though, with a couple o' minute to think... Is it possible that the overall voltage is much lower in your Anthem, and the Cary much higher... and in an attempt to equalize, your Anthem started cycling up with the Cary's unreleased voltage? I have had similar issues, and always think that it is better to go tube to solid, rather than solid to tube. I used to have a Marantz that was a digital processor, and would do the safety turn-off thing if I ran the tube preamp through its bypass, and then to the amp, verses ran the Marantz to the tube preamp. It had been fine when I had a pair of MA500's. Went over to a Rocket and started having the problem. Weird but true.
