@jrsub : did you hear back from T+A North America? I would also recommend contacting T+A directly. They come back pretty quick, and in English. Email address is e-service@ta-hifi.de
I would also pay attention to what @blisshifi is saying. It is possible there is compatibility issue between your Sony SACD player and T+A DAC 200, when playing back two-channel super audio CD via HDMI connection.
I looked at the T+A DAC 200 user manual, they only mention "connecting a blu-ray player" when talking about HDMI input. Also, there is this on page 59:
Since the DAC 200 is designed for pure stereo playback, only 2-channel PCM or DSD64/DSD128 encoded material can be played back via the HDMI inputs of the DAC 200. For playback via the DAC 200, the configuration of the HDMI output at the source device may need to be changed. Set the HDMI output to PCM output and activate DSD playback via HDMI if available. Always select the stereo track in the menu of the inserted disc.
