I'm wondering what's so special about AD711 for I/V, even in a metal can?
Looks like it would take a fair amount of modding to get it sounding good as it has what looks to be a single unified ground fill over the top side which normally indicates the designer has merged signal and power grounds together.
Do you see that.... AUDIOPHONICS I-TDA1387 TCXO DAC Raspberry Pi 3 / A+ B+ / Pi 2 / I2S - Audiophonics
sure the guys of Audiophonics read DIYA ! 8 x tda1387 !
for OP : maybe some nice AK cheap dac, look for on the digital Audio threads...

Looks very interesting thanks Eldam, I think I might have seen it before. They're sure using lots of caps - but if they'd read the long Malefoda thread then I wonder why they still went for 8 TDA's? Perhaps to get sufficient output current for a low output impedance to drive the inductors? I think its the first commercial TDA1387 based DAC with output inductors
