I have the HPA4 running both my office system and my Livingroom system via XLR and RCA outputs. My CODA #16 amp in the Livingroom has a STABDBY option as does the Schitt Wotan amp in the office.
I have it this way because I like to listen to the NS5000 during the workday when the house is empty. Unfortunately, I have to work from home then too. Sounds rather good from far away.
