Looking for a power conditioner/regenerator/filter

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.

Jallen, just FWIW but the big spike usually occurs when the power goes out, not when it comes back on. Its the same principle that makes the spark plugs run in a car.

If you want a good power conditioner, the very best made anywhere was made by Elgar. It is not an audio product, it is commercial/industrial. But it is high power, and can deliver a perfect sine wave at full power (28 amps). It is mechanically noisy, so it has to be installed at your breaker box and then the audio room AC power is then connected to it.

It uses a large isolation transformer, a low distortion sine wave oscillator that is synchronized with the AC line, and a feedback amplifier that is connected to a feedback winding on the transformer.

This is an expensive approach but it works, and other power conditioners are so much junk by comparison. Unfortunately you have to find them used as Elgar does not seem to make them anymore. Some are fairly old (over 20 years) and may have to be rebuilt, but if you want truly clean AC power this is the best way to do it.
