Cayin RU6 Portable USB DAC /Headphone-Amp Dongle featuring a 24-bit Discrete R-2R Resistor Ladder DAC, user Selectable NOS/OS Digital to Analog Mode and High Precision Resistor Array Volume Control supporting DSD256 and up to PCM 384kHz.
Cayin RU6 USB DAC Headphone Amplifier has the basic idea of an R-2R ladder is a matched pair of two resistors, the first is “R” and the other is “2R” which has twice the value of R.
To achieve 24bit R-2R decoding, Cayin needs 48 pieces of resistors (23xR and 25x2R) for one channel or 96 pieces of high-precision resistors for stereo.
R-2R is famous for its natural and realistic sound signature, it’ll offer a very different experience to music lovers.
R-2R DAC circuit is very demanding on incoming data integrity, and the digital volume of mobile phones will damage sound quality badly.
When off-the-shelf volume options cannot meet the high precision, low noise, low power consumption requirements of RU6, Cayin developed their own discrete resistor array volume control.
0-99 steps volume control through 9 segments of resistors and switching relays, meet all the RU6 requirements and transparent to maintain the natural sound signature of R-2R DAC.
Discrete R-2R is a low-power DAC circuit when compared to other highly integrated DAC chipsets on the market, minimising power drain from mobile sources.
USB Audio with shielded USB-C connector, compatible with a wide range of mobile, consumer electronics and computers.
High-end digital audio compatibility.
Choice of High/Low gain to enhance performance with different IEM or portable friendly headphones.
