Khadas Tone2 Pro DAC amp

The Khadas Tone2 Pro is a desktop digital-to-analogue converter and headphone amplifier with an ESS ES9038Q2M DAC and four OPA1612 operational amplifiers. It supports MQA decoding via the onboard XMOS XU216 processor for bit-perfect, asynchronous USB Class II playback. Balanced and single-ended outputs serve a range of headphones up to 150 ohms impedance.

What to check before ordering

Verify that your source device has a USB-C port or can supply a USB-C to USB-C connection for I2S data. Confirm your headphones use a 3.5 mm unbalanced or 4.4 mm balanced plug, or that you have suitable adapters for RCA line-level output. A 5 V USB power source within the 3 V to 5 V supply range is required for operation.

Who this suits and who should look elsewhere

Suits listeners who want MQA unfolding and a hybrid digital/analogue volume knob in a compact aluminium chassis. Not suited for users whose headphones demand more than 150 ohms drive capability or who need XLR connectors without purchasing a separate Balanced-RCA to XLR-3 adapter.

Questions about this item

What cables and adapters come with the Khadas Tone2 Pro and which connections must be purchased separately?

The box includes the DAC amp unit. USB-C and USB-C I2S cables are not included and must be bought separately, along with any 3.5 mm, 4.4 mm or RCA cables needed for your headphones or speakers.

How do I decide between the 3.5 mm unbalanced, 4.4 mm balanced and RCA outputs on the Tone2 Pro?

Use the 4.4 mm balanced jack for headphones up to 150 ohms that support balanced drive, the 3.5 mm jack for standard single-ended headphones, and the RCA line outputs for connecting to an external amplifier or powered speakers.

What does the ES9038Q2M DAC with four OPA1612 amplifiers deliver when driving 150 ohm headphones?

The ES9038Q2M DAC paired with four OPA1612 op-amps provides a three-stage amplification path that cleanly drives demanding audiophile headphones up to 150 ohms with low distortion and high dynamic range.
