I believe every home is different power wise and I honestly don't think I would benefit from power conditioning. My house of stereo is on a completely separate power feed from the main house and I experience zero hum, no background noise or interference of any kind. My system in there has always had the blackest background no matter what I ran. And even with stock power cables. I replaced them all with Patrick Cullen Gold series cables just to see if there would be any improvement and there was none. Now cable connects, that's a different story. Upgrading my RCA cables had a profound impact, specially on my digital gear. I do live in a small remote community with all underground utilities and that may be benefitting the quality of my power vs folks who live in big cities, specially in apartments. Plus building the house of stereo from scratch with a very capable electrician obviously paid off. BUT it turned out more expensive than a top of the line power conditioner
