Descriptions:

> Fully Balanced Discrete Class A Amplifier
> This fully balanced discrete Class A amplifier utilizes 4 pairs of power transistor to ensure ample driving power and superior control.
> The use of discrete components offers greater flexibility, allowing for precise fine-tuning of each stage to achieve optimal performance. This design approach also provies enhanced development potential. Furthermore, distortion characteristics are more manageable, enabling the circuit architecture to deliver a wider range of sonic characteristics with greater versatility. The post-amplification stage can be disabled, allowing the unit to function as a dedicated pure preamplifier.

> Preamp
> The preamp utilizes two socketed LME49720 dual op-amps. Preamp output can be disabled for seamless switching between headphone and speaker.

> Input Stage: Fully Balanced Topology
> Single-ended to balanced conversion circuit allows RCA inputs to benefit from full balanced drive performance.

> Built-in 30VA Low-noise Power Supply
> Also accepts an external 15-18V DC power input.

> Multi-stage Voltage Regulation
> Lower ripple noise and reduced interference for cleaner audio reproduction.

> R-2R Relay Volume Control
> Lossless precision adjustment with guaranteed channel matching across all 4 paths.
