So I got my adcom gfa-555 hooked up last night, and everything seems good with it. Caps looked ok, DC offset 3mA Left 27mA Right.
My only complaint is that there is a light popping noise every time an audio source is taken away or on shut-down. So for example if I am watching a tv show and I pause or fastfoward/rewind the DVR there is a audible popping noise. Same thing on a Blu-Ray opening menu when the theme music starts over. It happens any time the audio input is taken away.
I have done a bit of searching and have found a range of explanations from it being normal adcom behavior to adding resistors. My questions are: Is this normal? Will it damage my speakers? Can I fix it?
Thanks for your help
