The best power line conditioner is one that was not made for high end audio. It was made for commercial/industrial applications by a company called Elgar. It puts all 'high end audio' conditioners to shame.
By that I mean it can provide a perfect sine wave with a 28 Amp load (117V). No 'high end' conditioner can do that!
There are several problems that can be overcome. First is that its not being made any more but you can find them used through companies like Valutronics.
2nd, its mechanically noisy, but if you install it at your breaker box and run the audio room line off it there are no worries. An electrician may have to do this for you.
3rd, its not cheap, and may need refurbishment.
But it works the best and you can really hear the difference; universally better with all systems. No other conditioner can make that claim.
