I totally agree about the output section. They're really cheesy compared to
the first few generations of players and pro equipment and "audiophile"
goods. Most audiophile CD players make use of the same basic transports and
chip sets with special attention paid to the power supply and the output
stage. The best sounding mods I've ever heard were to power supplies. The
audio stages are just modulating a power supply that needs to be as clean
and low impedance as possible. A lot of push/pull and complementary
circuits are making up for half assed power supplies (canceling out the
noise).
