Bypass built-in CD player DAC


Quick question: if the digital output of a CD player is used to connect to an external DAC, is the CD player’s DAC bypassed or is the signal processed by the player’s DAC and then processed again by the external DAC? My old CD player has a bypass mode but the new one I am just testing doesn’t.
I compared the CD player and external DAC setup to CD Player without external DAC  setup via RCA connections and it sounded very similar, which makes me think that the CD player’s DAC is used. Bypass mode on my old CD player with external DAC sounds completely different.

Thanks!

Signals aren’t processed twice...if you are using a digital out with a CD player, then it should be passing unprocessed digitstowhatever you are plugging it into...
That makes sense as the internal DAC converts to analog and that can’t go into the external DAC. Still strange that both setups sounded similar although different DACs were used.
