I can run that but we need to decide what load resistance to test with.Has anyone run power consumption tests as well?
Yes for on the go phones I'd say 32 ohms is a good choice.32 is probably more real-world indicative compared to 300, but if there were two reference loads maybe you can determine quiescent power draw as well.
Personally, I would give up a little SNR for half the power consumption on the go, so this information would be really useful to know.
I think the easiest would be to try to get ahold of an iphone and then just drive it as a Roon endpoint as someone else suggested. I've gotten that to work with mine, but I don't have an audio analyzer...Makes sense since these are single chip devices so they had to use one with lightning support or one that could work with a lightning interface chip.
So has anyone figured out how to connect a lightning DAC to a PC? Is there lightning interfaces you can add that work plug and play?
So I got to test the Apple dongle on Android with USB Audio Player Pro. It doesn't work, UAPP doesn't recognize it and only electronic noise is heard. First time the UAPP driver failed me, had so far it had worked flawlessly with two DACs and two USB mics.I'll try it with USB Audio Player Pro next week if I can and report. UAPP comes with a special driver for audio which supersedes the Android driver, so the issue shouldn't appear, as long as UAPP "sees" the dongle as a DAC.
Uh......Recently upgraded my iPhone SE (which has a conventional headphone jack) to the iPhone 8 Plus which of course uses the lightning jack for headphone use. The lightning dongle works great with my 22 ohm Etymotic ER3SE earphones. Guess I can still use the Topping NX4 DSD with my 6th gen iPad and its headphone jack...

That's because the standard is anything but ...USB-C Dongles are such a crapshoot in interoperability.
The standard is fine. There are 2 options for audio through USB-C socket. One is analog(separate pins for that) and digital audio as usual. Not all smartphones support both of them.That's because the standard is anything but ...
Indeed, but the standard doesn't include a way for the consumer to identify what option has been implemented, other than trial and error after the purchase.The standard is fine. There are 2 options for audio through USB-C socket. One is analog(separate pins for that) and digital audio as usual. Not all smartphones support both of them.
