The Line Amp is capable of driving headpohnes through an RCA-to-PhoneJack Adaptor($10 from Monarchy)The Solid State output is recommended for Subwoofer connections, but may be used with any other preamp. The Solid State Output can also be routed through either a coupling transformer or a pair of RCA patch cord into the Tube Line Amp stage. This presents a slightly different sonic perspective than the Tube DAC through the same Line Amp. The front panel Push Button switch provides a very convenient means for selection between these two sources. Line Amp gain: Nominal 16dB(15-19dB tube dependent) Power Consumption: Approx. 50 Watt.
