Gustard Audalytic HP70 Fully Balanced Discrete Headphone Amplifier & Pure Preamplifier with Remote Control (Silver)

Gustard Audalytic HP70 Fully Balanced Discrete Headphone Amplifier & Pure Preamplifier with Remote Control (Silver)

• 【Fully Balanced Discrete Class A Amplifier】 This fully balanced discrete Class A amplifier utilizes 4 pairs of power transistors 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 provides 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.
• 【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.
