{"type":"firestarter.listing","listing":{"id":"lst_ZPiHi-4j","product_name":"TOPPING DX1 II Gaming Headphone DAC/Amp","category":"Headphone DAC/Amp","description":"Note (June 18, 5:39pm PT): This product is fast selling. We have limited stock and there will be times when the product goes out of stock. We'll try to keep this note up to date.\nKill the competition\nThe Topping DX1 II is a compact desktop DAC and headphone amplifier built for gaming, music, and everyday desktop use, combining low latency USB-C connectivity with the output power and precision needed for modern headsets and headphones. 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.\nESS DAC architecture with upgraded performance\nThe 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. \nFour-channel fully-balanced signal path\nThe 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.\nHigh output power from a USB-powered design\nDespite","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252818.jpg?v=1779216731","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252817.jpg?v=1779216669","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252816.jpg?v=1779216609","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252815.jpg?v=1779216550","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252814.jpg?v=1779216491","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252813.jpg?v=1779216433","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252812.jpg?v=1779216370","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252811.jpg?v=1779216313","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252810.jpg?v=1779216249","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252809.jpg?v=1779216189","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252808.jpg?v=1779216129","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252807.jpg?v=1779215773","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252806.jpg?v=1779215711","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252805.jpg?v=1779215649","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252804.jpg?v=1779215589","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252803.jpg?v=1779215530","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252802.jpg?v=1779215469","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252801.jpg?v=1779215411","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252800.jpg?v=1779215353","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252799.jpg?v=1779215288","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252798.jpg?v=1779215230","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252797.jpg?v=1779215170","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252796.jpg?v=1779215109","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252795.jpg?v=1779215050","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252794.jpg?v=1779214991","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252793.jpg?v=1779214931","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252792.jpg?v=1779214870","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252791.jpg?v=1779214809","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252790.jpg?v=1779214753","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx1-ii-gaming-headphone-dac-amp-1239252789.jpg?v=1779214689"],"price":119,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-
