Please engage with Allo and Audiophonics teams to get their DACs in DietPi configuration menu.
They are not broadly known HiFiBerry or IQaudIO, but certainly are outperforming these two mass market brands in HiFi quality.
Allo has two amazing DACs:

Audiophonics has average performing DAC (better than HiFiBerry DAC+ Pro but worse than both Allo DACs in my hearing):

However, Audiophonics has new promising DSD compatible DAC coming out hopefully Dec 2016 (not yet shipping, as they yet are struggling to finalize firmware):
