I have noticed that the VSX-521 will suddenly have a loud buzz come out of the speakers. It has only happened 2 or 3 times so far. I have had the unit in use for about 12 months. The only way to fix it is to shut the receiver down and then turn it back on. Anyone else notice this? Is it a defective unit, or is this something that happens now and then and is normal?
