I must say, probably to be expected, that I found this article frustrating. What could have been an opportunity to objectively evaluate upgrading your home electrical infrastructure had upon the mains quality ended in the usual subjective waffle (with most of it sounding unlikely given ASR measuremetns on mains quality effects).
