75-ohm cable is not correct for use with line-level
audio, but correct or not, it seems to work. And
because of its convenient termination, is becoming
the method of choice among installers.
That's not really correct. Video cable is spec'ed at 75 ohms, audio cable does not have an impedance specification so any impedance is fine. Most commonly used are 50 ohms or 75 ohms.
RG6 & RG59 both have the capacity to carry audio,
but their loss/ft ratio is constant, and will
affect any signal accordingly.
RG6 and RG59 do have different loss/ft ratio's. Belden publishes their dB loss per 100 feet for all their cable. However, the loss difference usually isn't too great.
