Powervar 1200 - How good?

I'd estimate they are very good. They do what they are supposed to do and are well designed and built. Hospitals and other places that have labs with very touchy micro electronics use them. Some equipment manufacturers actually require you to buy the Powervar or Oneac's for the warranty and or service contract to be effective. In printing, imagesetters I know are this way and cost tens of thousands of dollars but without the power conditioner in front you're sol if you have problems. As far as audio goes I can't say I can hear a difference but knowing my gear is protected and the lines are clean is good enough especially considering these things cost so little compared to "audiophile" conditioners.

I owned one. I did notice an improvement in detail and clarity. One thing I did not like was the transformer hum, which was constant.

I have a modifed powervar 12 and it sounds great.Sure does give a black background.I did add 3 - .47 sonicaps to the recepticles--1 cap per recepticle.

I have 3 caps left over if someone wants them.There are new .47 sonicaps --second generation.The cost was 8.50 per cap--i will sell them for 20$ and pay shipping.They take the powervar to another level in cleaning up the line.

They perform true power conditioning for the least amount of money...period.
