Have a chord tt2 dac and only has optical, usb and bnc. Strange no coax.BNC is coax with a different connector (75 ohm). Chord has been using them for quite some time, as do other manufacturers.
Coaxial bandwidth so much better vs optical.Optical can easily handle 24/192 with the right implementation and parts (i.e., Chord) and a proper glass cable. Which sounds better? Well, that’s quite subjective and depends on your taste/preferences and, of course, the implementation.
