@grannyring I understand that, but if there is no noise from the amp when it’s not playing, and no noise from the amp when everything is connected to it and switched on and it’s not playing, then surely there is no noise entering the system from the mains supply, or if there is the systems power supplies are dealing with it. It can’t just suddenly appear just because I start playing a flac file. Maybe the mains supply is generally cleaner here for some reason, as I have never had a mains noise problem or needed any mains conditioner, and I have used the mains supply in many places across the UK. Maybe the UK being smaller and having many power stations, we are all just closer to the source here, or maybe 230V as opposed to 110V has something to do with it? I don’t know, apart from 230V equipment drawing roughly 50% the current of 110V.
I don’t know how houses are wired in the US, here the downstairs and upstairs power ring are on their own breakers, as are the upstairs and downstairs lighting rings. Power rings are 2.5mm FTE cable and lighting is 1.5mm FTE cable, Also Immersion heaters and Cookers are on there own separate breaker/feed.
