Product code: OPPO HA-2 deals (PortableHeadphoneAmplifier)
The HA-2 is an excellent DAC as well as a headphone amplifier, with a full-size USB port for connecting to an iOS device and Micro USB for PCs or smartphones that support USB OTG. Using either will remove the digital-to-analogue conversion away from the connected device in favour of the HA-2's built-in ESS Sabre ES9018-K2M DAC, which in most cases will be superior. Asynchronous USB means the HA-2 controls the flow and timing of the audio datastream by ‘pulling' from the source device, rather than having it pushed. This can help cut down on audio jitter and other interference. It supports high-resolution audio and PCM up to an impressive 384kHz at 32-bit. We connected the HA-2 to desktops, iPads and Android smartphones, as well as in ear monitors and full-size cans, and heard improvements across the board. Trebles shine in particular, with a greater level of clarity in deals our high-resolution test tracks. Guitars being plucked sounded detailed and delicate and we could hear vocalists' int.
