Thanks for your suggestions. As I wanted to use a Tivoli PAL as my 'Amp & Loudspeaker', I finally took the PiZero + DAC again out of the PAL box and connect it externally with a ~5cm Audio-cable. Also, as you mentioned, I now use a separate battery (an old IPhone battery). The Pi Zero, the battery+charging circuit, and the DAC all fit in a small Pi3 enclosure, which sits behind the PAL. Works nicely - its my tiny travel / weekend home LMS setup.
