Speedskater said:Getting back to that transmission line business. We should remember that whatever the line's impedance is, it only holds for a narrow band of audio frequencies.
The bottom line of Jim's paper is that, as long as your cable is less than two thousand feet long, all you need to consider is its total series resistance and parallel capacitance. Its characteristic impedance is immaterial at audio frequencies.
This is a completely separate issue from the effects of loading on input and output transformers.
