We show that dark solitons are stabilized with respect to amplitude variations when phase-sensitive amplification and spectral filtering are used in combination to compensate for linear loss. In particular, we show that spectral filtering inhibits the sideband instabilities typical of nonlinear pulses and cw waves in periodically amplified systems, whereas phase-sensitive amplification inhibits the destabilization of the constant-intensity background wave caused by the filtering.
