OPPO HA2 HA-2 Portable Headphone Amplifier USB DAC High Resolution Sound Source

About this deal

This used OPPO HA-2 is a slim, portable headphone amplifier and USB DAC aimed at audiophiles and smartphone users who want significantly better sound than their device's built-in output can provide. Its genuine leather casing with contrast stitching and bevelled aluminium edges give it a distinctive, premium look. The HA-2 uses the ESS Sabre ES9018K2M DAC chip, the mobile cousin of the acclaimed 32-bit, eight-channel ES9018 Reference chipset found in high-end audiophile DACs. It offers two USB DAC input ports, one for Apple iPhone and iPod and another for Android devices, PCs and Macs, plus a 3.5mm input for portable music players without a USB digital output. The HA-2 handles PCM signals up to 32-bit/384kHz and can process DSD64, DSD128 and DSD256, while its Class AB amplifier delivers up to 300mW into 16 ohms. Two gain settings are included: High Gain for driving power-hungry headphones and Low Gain suited to sensitive in-ear monitors. The unit also doubles as a mobile power bank to charge your smartphone on the go.
