Hello. I'm hoping someone can help identify the cause of a loud "pop" when I turn on my Marantz SR6005. It seems to happen when I have the dedicated separate 2 channel amp and mono center channel amp on prior to switching on the Marantz. If I have the Marantz on first and then power on the separate amps it doesn't happen. I know I could always try to power on in this sequence, but other people may power-up as well and I would like to fix this if it is a problem. I always hear the normal little "click" when components come on, but this a LOUD pop, audible through the speakers. Thanks for your help.
