This O2/ODAC RevB combo unit is powered by the included AC adapter and you can select your required region below.

Awaiting stock of new ODAC RevB DAC modules, shipping expected to resume week commencing 18th May.

The headphone amplifier section has been designed from the ground up with a view to creating an objectively perfect design. This has been accomplished by months of development using top of the range audio testing equipment to fine tune and carefully select the optimum design, layout and components. The specifications achieved speak for themselves.

The high performance ODAC RevB DAC module is based on the SA9023 UAC1 engine and PCM5102A 24 bit DAC chip. It supports 16 bit and 24 bit at sample rates of 44.1kHz, 48kHz and 96kHz as well as 88.2kHz at 16 bit. The on-board filtered power supply ensures that noise is practically non-existent and a high quality on board crystal controlled oscillator is used which further improves overall performance.
