the Pi board on it's own experiences drop outs (audible clicks) with any format at or above 44.1kHz FLACs. Apparently because the Network and USB Ports interacts too closely somehow.
Is this problem cured with both the Digi and/or DAC boards?
Do these boards both connect to the I2S of the Pi, and does this not suffer from these problems then?
On last question:
If the Digi Board has a transformer, does the quality of the Powersupply for the Pi matter? (I assume with the DAC board it does in any case).
