I just received the following reply from the Devialet support email.
However, it still does not answer whether coax or AES/EBU will sound better for the master-slave connection:
Dear Sir
Thank you for your message.
For short cable length between master and slave, impedance mismatch is absolutely not an issue.
XLR input has 110R input impedance
COAX input and output have 75R impedance
We generally use a 75R COAX cable plus a COAX to XLR adaptor located on the companion unit. This works very very fine, is rather inexpensive (110R cable is much more expensive) and allow cable length up to around 10 meters.
