Where are you saying is the WM8805 SPDIF receiver in this post? That was the SPDIF receiver in the old AUNE X1, not the ASUS Essence One... I assume therefore you are the one mistaken. "Toslink can exhibit several 100ns of jitter" - do you mean "ps"? I'm pretty sure I show 100+ps difference with the Transporter's TosLink vs. coaxial if one were to calculate the peaks.
