what does a power conditioner really do?
It transforms cheap power into expensive power  ...

I am in Ontario, Canada. Ontario Hydro has installed smart meters. To maximize their profits, they feed us 125V. Big problem.

Unless I'm mistaken, manufacturers try to build for 230V/115V. There is a bit of leeway. 125V is too high, and bad for music.

I have a power regenerator, and it's awful. Not recommended.

I have a Torus toroidal cleaner. 125V comes in, 120V comes out. Ideally it could be adjustable to 115V. Unfortunately it does not.

The Torus feeds a 'Balanced' BPT conditioner. What a gem. Fabulous. I believe Chris is now with Equi-Tech. Highly recommended. Ideally you should look for a balanced conditioner which also allows 115V operation.

All things considered, I'd rather have unconditional power...

Oh, sorry.  Wrong subject...

Carry on...;)
Unless your mains is awful then don't bother as there is always an element of compression when using a conditioner.
If your mains is ok then choose a very high quality distribution block.

Actually, it transforms expensive power into more expensive power.
