I doubt that there is any place with really clean power. The power lines pick up all sorts of RFI and noise from neighbors sharing the same trunk feed. A typical home has its own share of noise sources--electronic devices, wi-fi, LED lights, etc. It does not hurt to do some form of power conditioning.
I use Isotek Titan and EVO 3 Sigma conditioners. These are quite expensive. But, at a demonstration at a local dealership, I heard their $500 power bar with conditioning, and it delivered a substantial proportion of what their much more expensive conditioners deliver. The power bar is quite a bargain.
