Noise Goblin

I moved into a 44 year home three years ago and it still had the original electrical box.  I had an electrician put the outlet I use for my audio system on a separate circuit.  Even still I was getting some noise through my speakers and when my wife was using the hair dryer in our bedroom upstairs I would get a buzz through my stereo amplifier.

Fast forward:  I just had a brand new electrical box installed with the latest grounding etc.  My audio system is on a separate circuit.  Low and behold this morning I started to hear the buzz through the stereo amplifier again.  I ran upstairs and my wife was using the hair dryer.  I am still getting a slight noise through my speakers. When I turn the volume up the noise gets louder.  

I don't understand how this is occurring.  Not sure what to do.  Are there any electricians or others who have had this same issue on this forum who might have an idea what is going on and how to correct this issue?

OMG your system is not dead silent? You can hear a noise when you turn the volume up? Send it back its defective. Either that, or normal. All depends on how much you have to turn up the volume and how easy or hard it is to hear. If you crank the volume to the most you ever use and can just barely hear it from where you listen that is normal, or certainly nothing to complain about.

My system is way noisier than that. If I spent even half the time trying to track down and eliminate noise that I do working on making the signal better my system would be quieter, yes, but sound nowhere near as good. You have a turntable. Is that dead silent? Is there zero groove and surface noise? I don't think so. Big picture. How bad is it, really?
