Power conditions for Integrated Amps

I traded in my Furman for a PowerPlant. I've NEVER plugged any integrated amps into a conditioner in 50 years.

I use power conditioner, but it's really more about surge protection since we have more than our fair share of power outages.  At this point I've chosen security over sound quality though it still sounds pretty great to my ears.  I didn't use the power conditioner when I had a Krell S-300i because it exceeded the capacity of the power conditioner.

I don't understand people describing their power "conditioners" as quiet.  Are they getting noise from the wall outlet that the conditioner supposedly eliminates?

Or are they misreading the specs and when a conditioner says it eliminates noise (meaning electrical noise) they listen their speakers to confirm?

i use gilbert yeung's passive filters for my power or integrated amps - they don't affect the power draw, seem to result in a slightly blacker background on most amps i have owned... pass labs is the exception, i cannot hear any difference
