    Why not DSP and Class D amplifier in One

    Have a look at: STA369BWS 2.1-channel 40-W high-efficiency digital audio system Sound Terminal (or similar) at http://www.st.com/web/catalog/sense_power/FM125/SC1756

    Most of the people using raspberry will play/hear there music , or the sound of there videos . They aren’t HiEnd-freaks. (I love good music, But most of the music I hear, have only the CD-quality.)
    I’m looking for a long time for a simple way playing music without transforming “Digital” via DSP via DAC to Analog amplifying with a class D ( means transforming to PWM and back to analog) with 2.1 loudspeakers (Left Right Subwoofer)

    The simplest way is: Digital source via I2S to DSP to PWM-Amplifier. The Switched Mode PSU can be external (so it’s possible to use a simple or a better one (like you have already build).

    I can’t do it by myself, but I think it’s relative easy for professionals.
