I am designing a test fixture for a cable assembly. It will need to connect to bare 20G solid wires, and handle up to 500VDC, low current.
I would like to stay away from screw terminals. In the past, I have used what look like stereo speaker push-buttons.
Anyone have any better suggestions?

I think push connectors might be the best. Look for high quality so they do not wear out. The voltage rating can be extended if need be by mounting them on a polycarbonate plate rather than metal.
Make sure it has a good interlock and some bleed resistors at both ends of the cables.

Usually push connectors for bare wires are designed for less or up to 200 circles ....
Depending on the number of test performed, mounting time, ... I would ask the push button manufacturers for test fixture connectors . Take the linecard of some distributors (digikey, RS ... ) to find them.
Might not be the cheapest solution on the first run, but for daily use good connectors are always worth the money.
