Descriptions:
> Fully balanced discrete Class A amplifier with 8 pairs of power transistors to ensure sufficient drive and control.
> Discrete devices are more flexible, allowing the parameters of each stage to be freely adjusted for optimal operation. It is also more developable and relatively controllable in terms of distortion, which allows for a greater variety of sound styles for different circuit configurations.
> THe power for the headphone amplifier can be switched off separately, making the device a pure preamp output.
> The preamp uses two direc-inserted LM49720 dual op-amps. The preamo outputs can be turned off for easy switching between headphone and speaker listening.
> The use of matrix relay volume, effectively ensure that the 4-way volume is consistent without bias.
> The input stage is fully balanced architecture. Single-ended to balanced circuit, allowing single-ended RCA inouts to benefit from fully balanced drive.
> High-speed, low-noise rectifier and main filtering using 4 Nikon nichicon capacitors.
> Low noise high current voltage regulator.
> Two 50W audio-specific custom torodial transformers, one for each channel, do not interfere with each other.
> Rigorous desgin, reasonable layout, tidy process and solid materials.
