iPhone support requires the USB-C to Lightning (Apple C78-USBH) cable, normal Lightning charging cables will not work. PCM 32bit 768kHz support requires a dedicated firmware package with digital volume control disabled. Performance testing based on USB input, coaxial input will have slight performance differences.

TONE2 PRO PRO
Tone2 Pro incorporates a 3-stage amplification system between the DAC and your 3.5mm single-end or 4.4mm balanced headphones. The onboard XMOS XU216 processor enables bit-perfect, hardware-native, USB class II, asynchronous "unfolding" of MQA data for both web streaming and local high fidelity audio playback, enabling future-proof "original master quality" audio reproduction just as the artist intended, but at reasonable file sizes and streaming bandwidth requirements. The latest addition to file format support is MQA decoding. These novel RCA ports have three signal-pins instead of two, yet retain the same size and form factor as regular RCA ports. Finally we've added an industry-first balanced RCA line-out. With not one, but two USB-C ports, you can connect a 5V linear power supply to the second USB-C port whilst having USB-C data on the first for excellent power-noise isolation.
The Tone2 Pro's aluminum enclosure incorporates a hybrid digital/analog volume control knob, allowing you to rely entirely on analog signal attenuation for accurate sound reproduction. Other additions to the Tone2 Pro include a 4.4mm balanced headphone jack in addition to the standard 3.5mm single-end jack. This 3-stage amplification pathway enables Tone2 Pro to drive a wide-range of demanding audiophile-grade headphones with impedances of up to 150 ohms. ESS ES9038Q2M DAC has been paired with four powerful OPA1612 operational amplifiers, and three buffer amplifiers. Tone2 Pro is our second generation Tone Board from Khadas that incorporates a variety of user feedback from our first-gen product, the Tone1.
