I don't know how homes are wired in Canada but in England we have a 'ring-main' system where sections of the house have a wiring circuit with sockets attached where needed. Anyway, in the house I had 35 years ago I put in a seperate mains spur for my hifi stuff, which got rid of the interference from the washing machine and microwave. :) So probably a good thing for you to have done.\n\nOr maybe not. These days any decent amplifier, or subwoofer, should have a power supply rectification and smoothing to handle any old rubbish mains problems. I don't know if you've ever read any of Amir's reviews on AudioScienceReview of the power supply rectifiers they sell to the gullible for hundreds of dollars. But they either do nothing or make things worse. So I reckon any decent, preferably surge protected, multi-plug will do.\n\nCoincidentaly, being nnear Black Friday (we even have it here in the UK now) I was checking out prices to buy more TP-link KASA smart plugs. Saw that they now have three outlet ones - see here. I ordered three.\n\nIn addition to being able to turn them off\/on via app they can tell you how much electricity is being used. Which I sometimes find useful to know.\n\nFor example, when in use but content paused (no sound) the A8A uses about 103 watts. When I'm playing music pretty loud it goes up to a massive - errr - 200 watts. o_O :D And my mains speakers are pretty inefficient. The sub amps are doing the heavy lifting of course. :)\n\nUK plugs are the best in the world. You have to know that, because most of the time when you are used to things from your country you lose appreciation about what's great in you country. Going oversee is a good way to find better things, and to really appreciate what you got before.
