What are the specs such as output power for both single ended, balanced, etc? @Andykong

Lightning cable? I thought RU6 is not MFI certified and MacBooks don’t have lightning ports???

Thanks, I am using the new iPad mini which does have a usb c port now

How do you find the “jelly roll” when the mini 6 screen is vertical? I have a mini 5 and was going to buy a 6, but this screen distortion I’ve read about is bothersome. 😒

Doesn’t bother me at all, especially when I realised my iPhone 12 Pro does the same thing. The biggest win for me is the form factor and weight, I find myself using it a lot to take notes

Yes, the mini size is perfect for me for multiple tasks. My mini 5 is going to need a battery soon, so I’ll probably trade it in towards a 6.

Our R&D has tested RU6 with Apple Lightning to USB Camera Adapter, it works fine with several iPhone, however we cannot guarantee that Apple won't change their systems down the road, I doubt if any vendor can guarantee that unless we go through the Apple MFI certification.

Do I need use the lighting to USB camera adapter? I thought I could just use the usb c to lightning cable to hook up with my iPhone?

The R-2R technologies of RU6 is based on the R01 Audio Motherboard of N6ii DAP. The decoding circuit of R01 is strictly PCM only, DSD bitstream will convert to PCM in the Audio Bridge, and the oversampled to 24Bit/768kHz before feeding to R2R resistor network. (For more detail, please refer to R01 functional diagram). In short, DSD is supported through transcoding.
Thank you, @Andykong! Does the RU6 balanced also output 430mW @ 32Ω like R01?

If RU6 outputs 430 mW in balanced mode, then the price of the dongle would end up around $619 (equal to price of N6ii R01).. No company would create a product to sabotage sales of their high end product.. In addition to this, I think Andy has mentioned about power consumption factors in designing dongles (specifically with iOS devices).. therefore we would be lucky if we see more than 200 mW @ 32 ohms balanced.. this is just a guess..

Strong probability you are correct, but a man can dream,
