help Cayin N5ii FAQ
Which DAC chip does the Cayin N5ii actually use?
The N5ii uses a single ESS ES9018K2M DAC, not dual AK4490EN chips. The AK4490 was used in the earlier Cayin N5, which is likely the source of the specification confusion; the distinction is documented in this [N5ii launch report](https://av.watch.impress.co.jp/docs/news/1096949.html).
Can the Cayin N5ii install Android music apps?
The player runs a customised version of Android 5.1 and was designed to allow compatible music applications to be installed through Google Play. Its 2017 software platform is old, so present-day app compatibility should be checked before buying.
How much storage expansion does the Cayin N5ii support?
The N5ii has two microSD card slots, which was unusual for a mid-range DAP released in 2017. The launch specification described support for cards up to 400 GB in each slot.
Does the Cayin N5ii have a balanced headphone output?
Yes, it has both a standard 3.5 mm output and a 2.5 mm balanced output. It can decode high-resolution formats including native DSD up to DSD256, according to the 2017 launch specifications.
