After releasing a few images of the DAC / AMP Cayin RU6 dongle using the Cayin 24 bit R-2R structure, this mannequin has been eagerly awaited and mentioned by worldwide audiophile. Let’s explore with Xuan Vu Audio through this introduction.Cayin RU6 Portable dongle

Design of Cayin RU6 dongle

Like the various portable DAC / AMPs, the Cayin RU6 R-2R comes with a simple, light-weight design with a metallic housing complete with 28g, easy to hold round and delights in high-quality sound.Cayin RU6 Portable dongle design

Feature of Cayin RU6 dongle

Cayin has received constructive advice from worldwide audio groups. Unable to go to this opportunity, Cayin immediately began researching and growing a portable DAC / AMP with this structure.

And the Mannequin RU6 R-2R was created to realize 24bit R-2R decoding; Cayin wanted 48 resistors (23xR and 25x2R) for each left-right channel.Cayin RU6 Portable dongle feature

And these resistors should have absolute sonic accuracy, they should generally work steadily with temperature adjustment.

Oversampling – oversampling. The sampling course of Cayin RU6 helps to increase the sampling frequency (upsampling).

Improve decision making, reduce noise and clear tonal variability, optimize frequency. Provides excellent material and varies in prolonged frequency.Cayin RU6 Portable dongle feature2

The R-2R circuit can claim too much for sound integrity, where digital volume management of cell phones will degrade the high quality of the sound and eliminate the low quality high quality sound.


While quantity choices cannot meet the Cayin RU6’s excessive precision, low noise, energy consumption requirements, the corporate has created a separate resistive array for its handling.

Where to buy Cayin RU6 dongle?

You can buy Cayin RU6 dongle from online shops like Geekbuying, Banggood, Aliexpress.
