Which DAC for RPI nano for headphone use?

Hello folks,

I am looking for a dac with a headphone jack to drive a B&O H4 headphone ( 20 Ohm I believe ).
I am already using a hifiberry dac, but the output level is too low to get a decent level of volume.

The dac I am looking for should fit a raspberry nano, if possible.
Thanks a lot for your help.
Cheers
Thomas

Here there are some hats with decent headphone outputs: osaelectronics.com/shop/

A Raspberry what? Did you mean a Zero?

Yep, I mean zero. Sorry… :smiley:

I’d go for an IQAudio setup, DAC & AMP:
