I just saw your questions. I apologize for that. Trying to do other stuff also. There was no storm. Both plugs are plugged into Monster Power Centers; not cheap strips. Maybe not the best, but everything has worked fine for almost 5 years. The main speakers did not change. Waiting for Golden Ear Triton Ones which will have to be put off now. I checked circuit breakers and none were popped, but I reset them anyway and no change. I was listening in analog stereo when it seemed to start being an issue. I really felt this amp should be able to break windows if asked. I was listening loud, since I was doing work in the room, but not at a level that was hurting my ears......
