Since audio cables carry alternating current, that 2000 ohms is a
quantity of impedance, not straight DC resistance, which is what most meters
measure.
I think he was giving an example of component-specifying-absurdity anyhow,
to illustrate that paying $90 for a matching transformer which will get rid
of a tiny bit of impedance-mismatch distortion is like paying $BIGNUM for a
2KOhm cable when bog-standard ones are 90 ohms.
