Its four-channel fully-balanced architecture, ultra-low noise floor, and -140dB channel crosstalk help preserve directional cues, imaging accuracy, and positional detail for competitive play, while up to 1000mW x 2 of output power provides headroom for everything from sensitive gaming IEMs to demanding over-ear headphones. UAC1.0 compatibility expands console support, customizable EQ presets and gain settings can be recalled through the included remote, and the compact footprint keeps your gaming desktop clean and uncluttered.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eESS DAC architecture with upgraded performance\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe DX1 II updates the original with ESS’s ES9039Q2M DAC, improving measurable performance across dynamic range, distortion, and signal integrity. Lab measurements show THD+N as low as 0.000056%, SINAD reaching approximately 125dB, SNR up to 128.8dB, and dynamic range extending to 128.8dB. FFT measurements reveal an extremely low noise floor around -160dB with harmonics well controlled below audible thresholds. \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFour-channel fully-balanced signal path\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe 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. Measured channel crosstalk reaches -140dB at 1kHz through balanced output, helping preserve image placement and stereo precision. Internal balanced topology also contributes to stronger voltage swing and output capability.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eHigh output power from a USB-powered design\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eDespite operating through a single USB connection, the DX1 II delivers substantial output capability through both single-ended and balanced outputs. The 4.4mm balanced headphone connection reaches up to 1000mW x 2 at 32Ω and 64Ω, with 230mW x 2 available at 300Ω. \u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eXMOS XU-316 platform with high-resolution support\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe 16-core XMOS XU-316 USB stage supports PCM playback up to 384kHz and DSD256 decoding.
