{"type":"firestarter.listing","listing":{"id":"lst_3NC000I5","product_name":"iFi ZEN Blue 3 Bluetooth Desktop DAC","category":"DAC (Digital-to-Analog Converter)","description":"\n\nAptX Lossless Bluetooth DAC and transmitter for Hi-Fi setups\n\nThe ZEN Blue 3 is a versatile Bluetooth DAC that both receives and transmits CD-quality audio wirelessly, and doubles as a high-resolution USB/S/PDIF DAC. With support for the new aptX Lossless codec and audiophile hardware design, it brings high-fidelity flexibility to your home audio or desktop setup. \nBi‑Directional Lossless Bluetooth\nThe ZEN Blue 3 is the first device able to both receive and transmit CD-quality (44.1 kHz/16‑bit) audio via aptX Lossless using Qualcomm’s QCC518x chipset and Bluetooth 5.4. That means you can stream from your phone to your Hi-Fi or wirelessly send music from your CD player to headphone speakers without quality loss. \nHi‑Res Codec Compatibility\nThe Zen Blue 3 also handles LDAC, LHDC/HWA, aptX Adaptive/HD/Classic, AAC, and SBC. LDAC and LHDC support up to 96 kHz/24‑bit hi-res streaming, ideal for audiophiles and non‑Apple devices. \nUSB‑C & S/PDIF Wired DAC Mode\nIn DAC mode, connect via USB‑C or optical/coaxial S/PDIF and enjoy wired playback up to 96 kHz (USB) or 192 kHz (S/PDIF). Balanced 4.4 mm Pentaconn and RCA outputs feed amplifiers or active speakers with minimal noise and excellent channel separation. \nLow‑Latency Mode for AV Use\nA front-panel low-latency button enables aptX Low Latency when transmitting, minimizing delay for movies and games—so sound stays in sync with picture. \nAudiophile‑Grade Circuitry\nInternally, the Bluetooth, DAC (ESS Sabre ES9023), and amp (MAX97220) are distinct. This separates functions, reduces interference, and uses a GMT femto-precision clock to limit jitter for clearer audio. \n\nProduct highlights\n\n\nAptX Lossless Receive & Transmit for CD‑quality Bluetooth audio\nHi‑Res codecs: LDAC, LHDC/HWA, aptX variants, AAC, SBC\nThree usage modes: Bluetooth RX/TX and wired DAC\nLow-latency button for AV sync during TX mode\nBalanced 4.4 mm & RCA outputs via wired or wireless input\nDedicated DAC & amp chips with precision clock\nUSB‑C ","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-dac-digital-to-analog-converter-ifi-zen-blue-3-bluetooth-desktop-dac-1176234744.webp?v=1768583106","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-dac-digital-to-analog-converter-ifi-zen-blue-3-bluetooth-desktop-dac-1176234747.webp?v=1768583106","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-dac-digital-to-analog-converter-ifi-zen-blue-3-bluetooth-desktop-dac-1176234743.webp?v=1768583106","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-dac-digital-to-analog-converter-ifi-zen-blue-3-bluetooth-desktop-dac-1176234745.webp?v=1768583106","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-dac-digital-to-analog-converter-ifi-zen-blue-3-bluetooth-desktop-dac-1176234746.webp?v=1768583106"],"price":299,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.534Z"},"share_url":"https://firestarter.network/l/lst_3NC000I5","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
