In Reply to: Long RG-59 Interconnect. HF rolloff? posted by The Rube on December 16, 2006 at 06:40:29:
as the center conductor in an audio application?Specs for capacitance vary, but 21.5 pF per foot seems like a conservative estimate.
The corner frequency for a 26-foot cable driven by a source with 100 ohms output impedance is 2.8 MHz.
This scales inversely with source output impedance. Your SS preamp likely has less output impedance, so the corner is likely to be higher. You should not have HF rolloff problems.
I'd expect the steel wire to have much more influence on the sonic performance.
