Product Characteristics
1. Fully balanced discrete Class A amplifier
2. with 8 pairs of power transistors to ensure sufficient drive and control.
3.The power for the headphone amplifier can be switched off separately, making the device a pure preamp output.
4. The preamp uses two direct-inserted LME49720 dual op-amps.
5. The use of matrix relay volume, effectively ensure that the 4-way volume is consistent without bias.
6. Two 50W audio-specific custom toroidal transformers
7. The preamp outputs can be turned off for easy switching between headphone and speaker listening.
8. The input stage is fully balanced architecture.
9. 2 levels of gains
10. Remote

Fully balanced discrete Class A amplifier: Using 8 pairs of power transistors to ensure sufficient driving force and control. The use of matrix relay volume, effectively ensure that the 4-way volume is consistent without bias.
2x LME49720 op-amps: The preamp uses two direct-inserted LME49720 dual op-amps. The headphone amplifier power and preamp outputs can be turned off separately for easy switching between headphones and speakers listening.
Low noise preamp: Equipped with low-noise high-current voltage regulator, two 50W audio-specific customized toroidal transformer, in terms of distortion, more developable and relatively controllable, to achieve a more diverse sound style.
Fully Discrete Balanced Headphone Amplifier: Discrete devices are more flexible, allowing the parameters of each stage to be freely adjusted for optimal operation.
2 Gain settings: GUSTARD H26 has two gain options, which are enough to cover a wide variety of headphones: low gain to drive the IEMs with high sensitivity, and high gain to drive full-sized over-ears.
