      Don't be dismayed, should your new parts sound less than ideal, upon first listen.

      The better the dielectrics used in construction, the longer the capacitors will take to sound their best.

                                                              ie:

        Also: the better caps will (usually) have their outer foil lead marked, to help with optimum orientation, in specific applications.
