Why DACs have no BNC Digital In


I've heard from several different sources that 75 ohm BNC digital connection is superior to a regular coaxial (to connect transport to a DAC), but looking at the back panel of most DAC's, I don't see any. Any explanation as to why that is? Thank you

Hey Brano-- bel canto has bnc input. You can come over and see mine and how it connects. John
The better dacs do. That Toslink garbage along with USB spreads like a weed.
I'm using the AES/EBU digital input port on my Bel Canto DAC, and thought this was a more common practice than you're suggesting. I 've also seen discussions that there may be more issues with S/PDIF. But for shorter cable lengths, I suspect that any differences may be relatively small.
@op, The reason why BNC is superior depends on the connector impedance...its hard to make a 75ohm rca cable.

A good read.

Hopefully dac manufacturers use it on the future?
