The DX1 II Utilizes the ESS ES9039Q2M DAC and Builds Upon its Predecessor, Making it a Great Entry-Level Option ESS ES9039Q2M DAC Four channel fully balanced headphone amp Up to 1000mW x 2 at 32Ω through 4.4mm output 10-Band High-Precision PEQ Compatible with Nintendo Switch and PS5 for gaming 3.5mm + 4.4mm outputs Plug and Play As a DAC/amp combo, the DX1 II connects to your source via USB and outputs audio through the 3.5mm single-ended to 4.4mm balanced headphone jacks. It provides a stable connection and is capable of driving most IEMs. DX1 II is equipped with independent optical input and output, supporting up to PCM 24-bit/192kHz and DSD64(DoP). It can also integrate with your CD player, TV, or game console, allowing unified PEQ processing before sending the signal to downstream audio equipment. ESS ES9039Q2M The Topping DX1 II is built with ESS's new-generation high-performance DAC chip ES9039Q2M. It upgrades the original, delivering a higher dynamic range and lower distortion performance. Fully Balanced The fully-balanced amplifier design uses four independent channels and separate left/right architecture from DAC stage through output stage. This approach improves channel separation while maintaining greater control across demanding headphone loads. Proprietary Low-Noise Power Supply Leveraging years of circuit design expertise, Topping has developed proprietary discrete low-noise reference power supply technology. It provides independent, clean and stable power for the DAC and analog amplification stages.
