i am just curious: If i am using my (beloved) LCD2c without the preset, i get a full synchron output via the (external PC)-DAC if using it together with another zone (in the same room / via roon-bridge on a pi + mqa-usb-dac, ztellas). If i switch the preset on, it get’s asynchron. It’s not a big thing to drop the headphones out…everytime…but… you get the point? Why is that? And is it even fixable?
