…Interested about internal DAC. I just knew the “amp” part and jack can deliver to high impedance devices, which is a good thing.
BUT, we don’t know about the dac. AFAIK, “Midi Setup Utility” still offers up to 96kHz resolution. It’s nice, but far from external i/o specs Logic can work with (e.g.)
I use an external cheap Topping d10 dac for music listening that is better than internal dac in my iMac.
What do you know about DAC in new MacBooks?
The feature you pointed, just better driving of earphones or external amps is a good one. But it has nothing to do with dac specs.
