Orpheus uses two tube gain stages with zero feedback and passive LCR equalizer with 2 inputs on RCA and one on XLR connectors. All inputs are balanced differential unless the grounding option is engaged on the RCA inputs. As we switch the ground plane when switching inputs there are no hum loops and induced ground noise. The input stage is a super low noise D3a German Post tube used as a triode. Loaded by a constant current cascade it provides the necessary gain and output impedance to feed the custom passive LCR RIAA correction following it. The switchable input transformer interfaces to MC cartridges and has selectable gain and loading impedance.
