Sounds like a lot of blown AI's. Is this really so common? I have been seriously looking at the Ten2 but this makes me a little gunshy now. As much as I appreciate good customer service I think the best customer service is a working amp. I'm hoping this thread just attracted a larger number of people who have dealt with the customer service and that most people have had no problems. Are these amps getting blown because of faulty wiring and construction or due to overuse/abuse? Also, is it mostly older amps that have had these issues? I would assume that any consistent problems would have been addressed in the newer amps. Does anyone have any reassurances to offer?
