Gustard A20H DAC/Amp



Due to the unfortunate fire at the AKM manufacturing facility in Japan, we have a very limited supply of this item. We urge anyone interested in this item to buy it while supplies last. Despite our very best efforts to get these products to customers as soon as possible, the impact of the fire on AKM’s operations may cause shipping delays. The AKM supply volatility will not improve until the end of April 2021.

The Gustard A20H DAC/Amp uses a native design so that every component including decoding and volume control is fully balanced. Two AKM AK4497EQ DAC chips, an XMOS U8 USB audio interface, and a powerful Class-A amplifier are some of the high-end specs that make this a premium device. It outputs 2,400 mW at 32 ohms to drive even the most demanding headphones while using a custom 50W dedicated toroidal transformer as a fully independent power supply.
