BNC or Coax?

Hi Everybody.

In connecting a USB converter (like a Trends 10.1 or CryoParts Pop Pulse) to a DAC, is BNC better than coax?

The name is a short form of "co-axial", which means that the central conductor and the woven shield share the same axis in cross-section. Also as he says, you can fit an RCA connector or a BNC connector to a coaxial cable. You could also fit twin-lead cable to an RCA connector but IME it would be a bit harder to do that with a BNC. Other connector types can also be used with coax cable. Phone plugs for example.

My experience and knowledge are small, however. Do you know of any true 75 ohm RCAs specifically? Eichmanns, maybe?
