Would love to hear if you come up with an answer. My XP3 has always had a noticeable hum. I did purchase a new impeller over the holidays. It seemed to quiet it down for a while. This last weekend, after my filter cleaning (every 6-8 weeks), the hum had returned.
I know many folks get completely quiet XP3s, but mine isn't one of them. The filter is in a open-backed cabinet, I throw a sizable blanket over the top of it, and I can still hear the hum in the evenings from a couple rooms away in my "open" Florida home.
I keep thinking about going with that "other" recommended vendor
...but I'm just too frugal and can always find something else to buy instead.
