My typical preamp is in the shop, so I am considering using the unbalanced (RCA) Analog audio output connections of my C658 to directly drive a tube Amp whose specification says ‘Input Impedance = 100 KOhms' (I KNOW running the this tube amp with NO INPUT connected WILL damage that tube amp, per the manufacturer). The Specs on the C658, under ‘Line input, Pre Out’ on the C658 say’...

• 'Line input, Pre out’ Spec state... '‘Output Impedance = Source Z + 240 ohm’ , and I guess I just don’t fully understand what that means.
• Will it be OK to drive this tube amp with that unbalanced output from the C658? Thank you! John
