as of two days ago, my amp has been acting funny. It would take a very long time to power up, and the power led would remain red for at least half an hour before it turned yellow. Then after a few minutes, it would just lose light, and I would lose all signal to my speakers. This happens with a loud cracking sound from within the amp. I have tried turning it off, and back on, and leaving it off for a day, but to no avail. The problem is getting worse and I'm afraid it will blow my speakers. I've sent NAD an email, has anyone had this kind of problems before?
