I have received a (new) replacement HD-AVP from the agent and it works as expected, thank you. Shortly, I will compile a list of "tweaks" that owners may apply to their units to overcome apparent faults and anomolies
To answer the last post, if you choose "Pure Direct" either on the remote or on the front panel, you will only get a stereo signal from a USB source, nothing from the rear channels
One upgrade or update that would be welcome, if it is possible, is to have DSD support on HDMI audio. This will enable a SACD player that uses HDMI output to play the SACD layer on discs.
Does the facilitator know if this is being considered? Also, what updates are in the pipeline. I am sure readers would like to know
