AC Line Problems

I have big problems regarding AC line noise. I get alot of loud "pops" through my phon stage from appliances in house while listening to phono stage. I had dedicated line installed from the existing panel but to no avail. The house is only wired for 110 amps. Would upgrading to 220 amps help? Any suggestions? How can I determine noise which is coming in from the AC line versus noise which is airborne?
