It's mentioned on the Oritek Audio site, but just barely. You have to look for it. I believe that it is solid-state, and the DAC is similiar to the separate DAC that he sells. It has a remote, an Alps volume control, 2 digital and 2 analog inputs. I believe one of the key components of its sound is its simplicity. I've not heard the Monarchy, but at home I use the aforementioned preamp with an APL 3910. I'm looking forward to comparing them at home.
