audio2design, Let's assume that amp draws from mains 1A during music peaks. It will likely be drawn in spikes of amplitude reaching 10A. If filtering coil has 1 ohm resistance it will cause voltage drop of 10V equivalent to 20% of max power loss. In addition inductor in series supposed to filter out high frequency content (electrical noise) while normal current (narrow spikes) also has high frequency energy. Of these two factors I would guess that inductive reactance of the coil will have bigger effect, unless inductor has high resistance (thin wire). Such power loss might only limit maximum output peaks in well regulated amplifiers but might still be audible at any output power in less regulated amps (zero feedback etc.)
My amp has the same dynamics plugged into Furman or the wall. Many people reported loss of dynamics with conditioners and that's the only plausible explanation I can come up with.
