Japanese Audiophiles Install $10k Personal Electricity Utility Poles

But what about all the wire coming from the power plant to his pole? Isn't the electricity there "dirty" too?

I wonder if any of these audiophiles have ever considered their own private power plant.

That's all 60Hz AC coming from the power company, and the only thing connected to it are the step-down transformers en-route to your house. Not much there to generate noise.

Try the following experiment: Go through your house and count how many "wall warts" you have plugged in.

Two decades ago, 100% of those were simple, inefficient, low-noise, transformer+rectifier+caps AC/DC converters.

Now? 100% of them are high-efficiency DC/DC switching power supplies. These power supplies create switching spikes -- a kind of noise which is extremely high frequency and has a nasty habit of propagating places you don't want them to go. The thinking which leads to having your own power pole installed is that some remnant of these spikes are propagating into your house from all of your neighbors.

Having your own power pole installed is one way to address that, but I'd think that $10k would buy you one hell of a 60hz band-pass filter...
