Input stages
Most of the input stages have remained the same as in preceding ST-Audioprocessors with
exception of the CD-inputs (see
the market which have a significant high source-impedance which effects strongly the
common-mode-rejection of the normal differential input stage.
The additional buffer of the TDA7404 Diff:

input avoids this drawback and offers the full common-mode-rejection even with those
CD-players.
