Cayin Released R01 Latest R-2R Audio Motherboard for N6ii

Today Cayin officially released its much-awaited R-2R DAC Audio Motherboard, the Cayin R01. It is the sixth and the last audio motherboard Cayin has planned for the N6ii Android music player. The R01 brings innovative 24-Bit R-2R Ladder DAC technology with a balanced headphone amplifier architecture. It supports up to 430mW of power through the balanced 4.4mm connection and up to 240mW output power through the 3.5mm single-ended output mode. R01 supports PCM decoding up to 32-Bit/384kHz and DSD up to DSD256 natively. The R01 Audio Motherboard is available to purchase from our store for 619$.

Discrete 24-Bit R-2R Ladder Resistor Network DAC:-

R-2R Ladder is a matched pair of two resistors, where the 2R has twice the value of the R. After āextensive research Cayin has adopted 5.1kohm as R resistor and 10.2kohm as 2R. The R01 audio motherboard consists of 48 pieces of Resistors(23 R+25 2R) for each channel, a total of 96 pieces of resistors for stereo configuration. R-2R DAC’s are only found in exquisitely premium products, they offer natural and realistic sound tonality with high-resolution clarity.

Implementing the R-2R DAC:-

24-Bit Discrete R-2R Precision DAC converts the digital signal to analog through a high-precision R-2R Resistor ladder network. It provides precise Hi-Res signal decoding with ultra-low distortion and high SNR ratings. R-2R DAC’s decode the audio signal in their true form producing a natural sound with high quality.

Uncompromised Design For Accurate Sound Decoding:-

Both the left and right channels in the R01 adopt low noise high-power LDO linear regulators as a reference power supply for the circuit. With clean power, responsive transient, High PSSR, and low-noise power supply system, the decoding quality is simply top-notch. You won’t notice any single issue and will find your best companion with the N6ii Audio Player.

Cayin R01-3

Powerful Balanced Headphone Output:-

Cayin R01 houses two headphone output ports, one single-ended 3.5mm and another balanced 4.4mm port. It has a fully balanced parallel headphone circuit that provides a powerful output of up to 430mW through the balanced port. Even through the single-ended 3.5mm port, the R01 has an output rating of up to 240mW@ 32 ohms.

Pricing & Availability:-

Cayin R01 is available to purchase from our store for just 619$. Order yours here.
