Got my PiFi Digi V1.0 today and installed with HiFiBerry settings.
It works fine, but the display case has to be cut to allow for optical and phono connections, and that is the trouble.
Is there any difference in sound quality between using HDMI audio out and optical/ phono out (on PiFi) as they are both fed to Onkyo TX-RZ820 AVR for D/A conversion?
Thanks!
This is a loaded questions and depends on various factors in your setup. Generally, the DAC at the end of your digital signal is the most important factor. But I would recommended testing both outputs yourself with your setup and seeing if the sound card makes a significant difference.
