Wondering if HDMI Audio is still recommended as best for CD/SACD playback? Will there be any change in that recommendation after the upcoming upgrade is performed on the unit?
It depends on the player and the receiver. If the receiver has better DACs, then use HDMI. But if you have a really good player, like a TOTL Oppo or Sony XA5400ES, then have the player use its internal DACs and send the signal to the receiver using the analog outputs. The top Oppos uses stacked DACs for better sound which surpasses almost any receiver's capabilities.
