Hopefully I'm not hijacking the thread, I'm just trying to wrap my head around the interactions and the math.
So, if a volume pot or a fixed voltage divider is used to reduce the output signal (and associated noise in this case) of the preamp then putting the pot after the interconnect (on the amp) would not increase the output impedance of the preamp. Correct?
If the preamp is driving a SS or Class D amp does this affect the placement of the volume pot? I assume that there is no Miller capacitance or the equivalent involved in that case. Or is there?
Would the resistance in series have the same effect on the output impedance if there was no Miller involved, only the cable capacitance?
