{"type":"firestarter.listing","listing":{"id":"lst_N6JLKTbP","product_name":"xDuoo TA-10R Tube DAC/Amp","category":"Headphone Amp (Tube)","description":"All-in-one powerhouse \nThe xDuoo TA-10R is a desktop DAC/Amp with a totally upgraded chipset, optical and coaxial inputs, DOP64 support, plus a striking red exterior. As a DAC/amp, this unit can both decode digital files and amplify them for headphones, making it a great purchase for anyone looking for an all-in-one desktop solution.\nWarm tube sound\nMost modern solid state amps reduce distortion beyond the threshold of human hearing. Tube amps, on the other hand, add distortion. So why would anyone want one? Many people love the quality of the distortion that tube amps add. They can pare back some of the shrillness and extension of the upper-end, and boost the mids and bass for an altogether warmer sound. \nSwap tubes for different sound signatures\nOne of the joys of tube amp ownership is that the tubes can be swapped out for other tubes. Each tube has a different sound signature, adding or subtracting qualities like warmth, detail, and soundstage. It’s a fun way to play with the sound signature of a single amp, often for less than $30 a pop. Just be sure to find a reputable dealer of tubes before buying. \nUpdated Chipset  \nThe TA-10R features a totally updated chipset. The AK4493EQ DAC chip and XMOS XU208 USB chip are capable of decoding 24-bit PCM up to 384kHz, DSD256, and 32-bit DXD up to 384kHz. These file formats are of much higher quality than MP3, providing detail and fidelity that are closer to the quality of master tapes. \nEight inputs and outputs\nThe xDuoo TA-10R features four inputs (optical, coaxial, RCA, and USB) and four outputs (SPDIF, RCA, balanced XLR, and 3.5mm SE). This combination allows you to connect a variety of sources, headphones, and speakers. \nProduct highlights \n\nDAC chip: AK4493EQ\n8 in and outs\nInputs: Optical, Coaxial, RCA, USB\nOutputs: SPDIF, RCA, Balanced XLR, 3.5mm SE\nUSB chip: XU208\nClass-A Amplifier\n\nSpecs\n\nTube: ECC82/12AU7\nDOP64 input: supported\nPower supply:external electricity (AC100-240V)\nScreen: 0.96” OLED\nCompliant OS: Win7, ","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-23041396834475.jpg?v=1628203237","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-29033478127787.jpg?v=1740196012","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-23041193115819.jpg?v=1740196012","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-23041529151659.jpg?v=1740196012","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-23041542586539.jpg?v=1740196012","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-23041133084843.jpg?v=1740196012","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-23041125875883.jpg?v=1740196012","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-xduoo-headphone-dac-amp-xduoo-ta-10r-tube-dac-amp-29033444442283.jpg?v=1628203237"],"price":319,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:01.109Z"},"share_url":"https://firestarter.network/l/lst_N6JLKTbP","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
