JackD, here are more details. I tried installing Liberty Cables at 10pf/ft. However in order to for me to install, I had remove the outer jacket, outer copper braid, and the foam PE insulation to expose the central two individual insulated wires for about the last 4 inches, therefore, the wires were not completely covered by the metal (RF?) shield. I got excessive hum.
I also have Blue Jeans cables that are of similar thickness to the Liberty Cables, but i did not try. How thick are the Monoprice? I can certainly try them, if thin enough. Just not a lot of room to thread it through a small slot to solder on the PC board.
