Also, as I pointed out, the digital output of the Sonore is limited to USB, whereas the digital outputs of the Bricasti M5 (and Auralic) are robust and don’t restrict one’s choice of DAC. That was my primary point.
Sonore offers the ultraDigital as an addon to the opticalRendu. This give you a SPDIF output and most importantly an i2s output. Very few network players that I have see have an i2s output.
i2s is the best input on many DACs.
