I know the D104 is very sensitive to the cable used, on mine,
only the cable that came with the mike works well at all.
This was on a line level link between the output of the mike
preamp and the power amp, lowish impedance I thought.
I measured the capacitance of the cable and got something like 
10 PF? I think.

And how would a cable be an efficient transporter of RF but not
audio frequencies?
Surely capacitance or inductance would impair RF more than audio???

Resistance is not a problem in rg8m...
