Jung, junge, gleich mal in eine der Datasheets geschaut und über folgendne Sätze gestolpert:
"Most fully integrated switch-mode amplifiers are not intended for high-fidelity audio applications. Instead, devices
such as the MAX4297 are intended for portable, battery-powered equipment such as cellular phones, portable radio/
CD/tape players, MP3 players, laptop computers, PDAs, and portable DVD players. Consumers of those products are
lured by the promise of portability and how long the device will last on three AA batteries, not by the expectation of a
stunning, theater-quality audio experience. As the market for portable devices continues to grow and Class D
amplifiers gain acceptance, you can therefore expect to see more switching amplifiers, featuring greater flexibility and
higher levels of integration."

Also nix mit High-Fidelity, sondern billiger Kopfhörerausgang, bei dem man in der Bahn eh mehr vom Zug als von der Musik mitbekommt.

Danke Manf für die Links. Sehr interessant.
