A regulator that improves rejection from 85 dB to 110 dB will make the same difference as a really huge and impractical capacitor substitution. A capacitor which is too large stresses the transformer rectifier diodes when power is applied, because the bigger the capacitor, the bigger and more sustained is the inrush current.
