This person finds the DAC to be extremely high quality: https://www.kenrockwell.com/apple/lightning-adapter-audio-quality.htm https://www.kenrockwell.com/apple/lightning-adapter-audio-qu... . Perhaps it’s a placebo. Perhaps the performance has degraded. Or perhaps his measurements are wrong.
- mumblemumble 7y agoOr perhaps there's a manufacturing error or some cable damage in the one I listened to? Or, for that matter, I have no idea what the impedance was on the headphones I was using; it was a pair of cans that could well have been more than 100ohm. In any case, thanks for sharing. These test results are definitely reassuring.
- dan-robertson 7y agoWell he tests at 35Ω and 200kΩ so probably not resistance, and the output impedance is very low. It may be that you’re used to hearing certain artefacts from other sources (eg you get totally different harmonics near the upper limit of a valve amp compared to a solid state one), or that the headphones could not be driven at a sufficiently high voltage. But the dac in the dongle is either the same as or better than all the dacs in iPhones with 3.5mm jacks so having a headphone jack wouldn’t help there.
- marrone12 7y agoYes, I agree. I personally find the dac in the lightning connector to be pretty solid. Not as good as the interior one with headphone jack, but pretty solid overall.
