The CAYIN RU6 uses a 24-bit discrete R-2R DAC with low temperature coefficient resistors to maintain precision and stability over time. The inclusion of a low-pass filter module enhances the bass performance, while the three-way crossover and separate digital and analog boards preserve signal integrity for a clear, balanced sound profile. The device also features non-oversampling and oversampling modes, providing audiophiles with both traditional and high-performance audio processing options.
