Gustard H20 Balanced Headphone Amp
Extremely Powerful
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. Complete with an all-aluminum chassis, a fully balanced architecture, and two LM49720 dual opamps, the H20 has already garnered a lot of excitement from Head-Fi users.
Note: Only silver color is available.
