IME, 2K is not adequate for more than short runs.

Huh? What do you mean? A typical consumer amp shows an input R of more
than
10 KOhms.

Actually, that's the standard EIA worst case input impedance for consumer
electronics. Many pieces have higher input impedances, often around 100K.

A 5532 can swing nearly all the way to the rails in such a load...

Exactly!
