With the DAC, Gustard offers a high-performance headphone amplifier and preamplifier, benefiting from careful and intelligent manufacturing. With its independent symmetrical and asymmetrical circuits and capable of delivering a high level of power, it can be used with most of the headphones on the market.

Its preamplification and power stage is based on one LME49722 chip and two LNE49724 chips. It is thus capable of delivering a power of 3700mW under 64Ω on its balanced outputs, while offering a detailed, rich and dynamic restitution. The inputs are accompanied by a buffer using an AOP OPA1642 and an AOP OPA1678.

Also at the heart of the device are an Altera CPLD and an STC MCU, responsible for processing audio signals quickly, while ensuring low jitter.

On the power supply side, the H16 incorporates a linear power supply, using a custom-made toroidal transformer, in order to cleanly power all the audio circuits.

Finally, the volume level is adjustable thanks to a relay volume control, making it possible to maintain a perfectly identical sound level on both channels.
