One of their other products is something I wondered about the existence of: a passive pre-amp with powered remote control, and it even has a HT bypass setting.

Think SYS with a motorized pot, which is something I've heard people ask for before on this forum. I could totally picture that in a Schiit box, but the power switch would be on the back, of course, and you would toggle through the inputs one by one with a single button on the front. Of course.
EDIT: Are there other examples of passive pre's with remote power volume and switching that I'm not aware of? The price on this one is around 450-500€ depending on options.
