4% variation in voltage should be no worries. If the equipment cannot manage that it can be considered to be problematic. It is useful to ask what voltage the equipment is set up for though. If 235V instead of 240V, 250V is boarding on excessive.
It is worth it to see if the PSAudio solves the problem. If so *then* we can conclude that the problem is AC related.
Just for the record: a 'spike' cannot cause the kind of problems described. Neither can the weather, unless its a secondary effect, such as people running air conditioners more and causing a brownout.
