"The power to my house comes from the pole on the road, then underground to a large box that I assume is a transformer. This supplies power to my house only: there are no other houses within 1000’. Does this mean that I am getting very clean power?"
I live in a rural rea with a similar situation-- we have our own transformer, as does each house on our sparsely-populated road.
A friend who was a PS Audio dealer at the time brought over one of their upper-tier power regenerators and neither one of us could hear any effect, whatsoever. Am I suggestion you wouldn't benefit from power conditioning ? No, but I am suggesting the only way to tell is to try it. No-one here can give you a definitive answer.
