are all power conditioners noisy?

I just received a powervar, and I don't know why I didn't think of it before, but this stonkin' big transformer hums!
I've read reviews where they complain abount the amount of fan noise in some companies products.
To me, the power conditioner adding background noise- even though it's not coming out of the speaker, is very distracting.
Is there such a thing as a silent power conditioner, or should I just give up?

Both the Powervar and OneAC brand conditioners are known to hum. They do the job well...but they hum like beehives.

I use a Oneac that doesn't hum and have had Powervars that didn't hum at all. One thing to try is to tighten the transformer nut down some.

Like I said, Powervar and OneAC conditioners don't all hum (but I've read this is a common complaint.) ;)

My OneAC hums.

Silent power conditioners? Certainly. Audio Magic, Soundapplication, Hydra--to name but a few...

I use a Panamax Max 5500 ACRegenerator that uses a large transformer to decouple wall AC from AC provided to equipment... my ear has to be practically right up to the unit to hear any noise at all... and even then it's extremely low in volume.
