{"product_id":"ibasso-dc04-pro-dual-dac-converter","title":"iBasso DC04 PRO Dual DAC Converter","description":"\u003cp\u003eThe iBasso DC04 PRO is a hi-res USB-C dongle DAC and amplifier with two Cirrus Logic CS43131 DACs, two RT6863 amplifiers in a true balanced design and iBasso’s own FPGA with a KDS femtosecond clock. It adds a 3.5mm output to the original DC04’s 4.4mm balanced, gives 280mW into 32Ω balanced, and measures a 131dB signal-to-noise ratio with a noise floor of just 0.9µV, all in a 21g CNC aluminium and glass body.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/ibasso-dc04-pro-dual-dac-converter-photo-hero.jpg?v=1791389459\" alt=\"iBasso DC04 PRO hi-res USB DAC and amp\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/ibasso-dc04-pro-dual-dac-converter-photo-tiles.jpg?v=1791389462\" alt=\"iBasso DC04 PRO features at a glance\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/ibasso-dc04-pro-dual-dac-converter-photo-parts.jpg?v=1791389466\" alt=\"iBasso DC04 PRO in black and blue\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eDual CS43131 with a pure power supply\u003c\/h3\u003e\n\u003cp\u003eThe two Cirrus Logic CS43131 flagship DACs, with Master HIFI technology, decode PCM up to 384kHz\/32-bit and native DSD256.
