Power conditions for Integrated Amps

I had a Furman, and i didnt like the results. I now have a Saturn 103C on both of my systems, and everything is plugged into it. dead quiet ZERO noise. The Saturn are capacitor based. I opened them up and had a look. all caps.

I use 2 Chang Lightspeed units, one for my audio system and one for the video system, They are dead quiet, do not limit current and are an asset to both systems. Check them out:

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?
