I think it just needs that 5V to make a successful handshake between the devices. I am just happy it pairs with HUGO as 24/192 optical out via Ak120 still fails to work. I am happy to get a 128 GB microSD and I am set, shame I cannot get it to work with Denon DA-10 which is a great sounding device.
The NW10 does charge the device but I was hoping to use it as walkman to microUSB data connection but obviously the song people are smarter than that. The Denon DA-10 has an internal battery that powers the device. I can use it when paired with apple camera kit connection so I assumed it will work with A15. What is strange is that A15 does work with HUGO which is a relief.
An update on this just got the WMC NWC10 and it does not work. I know it was not going to but tried. Using the WMC-NWH10 (the cable designed for digital out) I can get a connection for 24/192 files with my chord hugo but sadly no luck with Denon DA-01. Denon DA-10 pairs with ipod touch 5G using cck so yea.
