Sure - the need for a wall outlet direct connection for AC input and the need for storage capacitors for DC power in power amps are the same - very large instantaneous current demands for music's transients. AC power outlets can supply 10000A+ for very short periods, I doubt any power conditioner can match that #. Paul may try, but alas it would be grossly expensive to do so...
Preamps and other line-level devices do not have the very large current demands. This is due to the fact that impedance levels are much higher (100x or more) as well as signal size being lower (100x lower as a rule of thiumb).
