A sequel to the popular H10, the Gustard H20 is a powerful class-A headphone amplifier with a variety of inputs and outputs. In fact, with an output of 12,000 mW at 32 ohms, it’s one of the most powerful we’ve ever sold. In addition to the 4-pin XLR output, it has a 6.35-millimeter low gain and a 6.35-millimeter high gain. There’s even an output for dual 3-pin XLR: a welcome sight for those who use this rarer balanced out with their headphones. Two XLR outputs function as a prestage and are ideal for sending out to high-end studio monitors. Each channel uses two independent amplifying units to form a symmetrical output line. The front class consists of a single 4-way amplifier circuit, using two LM49720 dual op amp. Have a separate pre-stage output,can be connected to active speakers or pure after the class. The use of matrix relay volume,effective to ensure that 4-way volume unanimous; The H20 has already garnered a lot of excitement from Head-Fi users.

Topping A30 Desktop Headphone Amplifier (NEW)

A30 received a lot of praise during the exhibition.
A30 can build a suit set with D30 and other mini speaker amplifier (other products and the shelf need to be purchased separately).  The mini Desktop Rack pricing can be found from below picture link


This can be a good alternative to the Schiit Headphone Amplifier + DAC bundle.

– Two outputs for different impedance of the headphone: 3.5MM and 6.35MM headphone port, can be used for a variety of headphones and earbuds.
– Two kinds of operating voltage mode and three kinds of gain (0dB / 9dB /18dB) selection mode.
– A30 uses the high-performance TI HIFI chip OPA161, OPA2134 (changeable) and TPA6120.
– Maximum output power of A30 can reach up to 1551mW * 2.
– Aluminum body, each part is through high automation, high-precision machining creating (Laser engraving).
Power by a special customized three-way high-performance linear power supply
Most competing products use 1x15V or etc adapter to the amplifier, this 1x15V will be convert inside the amplifier and cause noise and interference. But we use linear power adapter to provide 2x15V and 1x8V to A30, which help A30 avoid these problem. 2x15V used for high fidelity headphone amplifier circuit. 1x8V used for MCU, LED and relay. Less noise, less interference.
