Dovjm,
As others have stated it depends on the design and quaility of the particular conditioner.I have 20 amp dedicated lines and my various tube amps sound good plugged into the wall. However the sound improves quite a lot when plugged into my BPT3.5 Signature Plus conditioner(uses a large high quaility/high current balanced transformer). Every sonic parameter is better with no down side. The noise floor is lowered with exceptional dynamics,inner detail, sense of ease and relaxation and an enhanced realism and live presence.
The blanket statement that power amps are ALWAYS better directly plugged in the wall outlet is a tired cliche.
