{"product_id":"igs-audio-daco","title":"IGS Audio DACO","description":"\u003cdiv lang=\"en\"\u003e\n\u003cstrong\u003eIGS Audio DACO\u003c\/strong\u003e\n\n\u003cp\u003eDACO is a digital-to-analog converter with a tube output stage, designed and manufactured in Poland by IGS Audio. The digital section is built around a dual AK4493SEQ conversion chip (AKM) – among the more highly regarded DAC silicon in the hi-fi segment – managed by an AK4118 digital receiver (AKM) and a QCC5125 Bluetooth receiver (Qualcomm). After conversion, the analog signal passes into a tube output buffer built around a pair of NOS military-grade 6N6P-VI valves (alternatively 6N30P), operating without global negative feedback. The buffer is transformer-balanced at both input and output with full galvanic isolation from the output stage. All transformers are custom-designed and supplied by UTM Industry. A linear power supply with a GZ34 tube rectifier and ultra-low-noise filtering stabilises the voltage rails feeding the tube and analog stages.\u003c\/p\u003e\n\n\u003ch3\u003eDigital input architecture – what DACO accepts and at what resolution\u003c\/h3\u003e\n\u003cp\u003eDACO accommodates five types of digital input: AES\/EBU, S\/PDIF, ADAT, USB, and Bluetooth. The USB input handles PCM up to 384 kHz and DSD64, DSD128, DSD256, and DSD512 – the full range of hi-res formats available from streaming services and local digital libraries. AES\/EBU, S\/PDIF, and ADAT inputs support PCM up to 192 kHz. Bluetooth via the QCC5125 Qualcomm chip covers up to 96 kHz, which in practice handles LDAC hi-res streaming. A 2-inch OLED display on the front panel shows the active input and current sample rate; an input selector and IR receiver window add remote control operation. The 380×290 mm enclosure is machined from 3 mm aluminium CNC and weighs 6 kg.\u003c\/p\u003e\n\n\u003ch3\u003eTube output buffer and analog performance\u003c\/h3\u003e\n\u003cp\u003eThe 6N6P-VI tube is specified for exceptionally linear operation and low self-noise – in the context of a DAC output stage, this translates to wide soundstage, micro-dynamic resolution, and the absence of the flattening effect common in cheaper solid-state output stages. Designing without global NFB preserves the full sonic character of the tubes while maintaining distortion at THD below 0.03% at 1 kHz and 0 dBFS. Frequency response extends from 8 Hz to 80 kHz (±1 dB); dynamic range measures 112 dB per AES17. RCA output delivers 2.5 V RMS unbalanced; balanced XLR output provides 5 V RMS. Power consumption is 45 W.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDual AK4493SEQ DAC (AKM) + AK4118 digital receiver (AKM)\u003c\/li\u003e\n\u003cli\u003eTube output buffer: 2× 6N6P-VI or 6N30P NOS military-grade\u003c\/li\u003e\n\u003cli\u003eNo global negative feedback\u003c\/li\u003e\n\u003cli\u003eTransformer-balanced tube buffer I\/O with galvanic isolation\u003c\/li\u003e\n\u003cli\u003eLinear power supply with GZ34 tube rectifier, ultra-low-noise filtering\u003c\/li\u003e\n\u003cli\u003eInputs: AES\/EBU, S\/PDIF, ADAT, USB, Bluetooth (QCC5125 Qualcomm)\u003c\/li\u003e\n\u003cli\u003eUSB: PCM up to 384 kHz, DSD64\/128\/256\/512\u003c\/li\u003e\n\u003cli\u003eOutputs: RCA 2.5 V RMS, XLR 5 V RMS (balanced)\u003c\/li\u003e\n\u003cli\u003e2-inch OLED display, IR remote control\u003c\/li\u003e\n\u003cli\u003eFrequency response: 8 Hz – 80 kHz ±1 dB\u003c\/li\u003e\n\u003cli\u003eDesigned and manufactured in Poland\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: digital-to-analog converter with tube output buffer\u003c\/li\u003e\n\u003cli\u003eDAC chips: 2× AK4493SEQ (AKM, dual)\u003c\/li\u003e\n\u003cli\u003eDigital receiver: AK4118 (AKM)\u003c\/li\u003e\n\u003cli\u003eBluetooth receiver: QCC5125 (Qualcomm)\u003c\/li\u003e\n\u003cli\u003eBuffer tubes: 2× 6N6P-VI or 6N30P (NOS military-grade)\u003c\/li\u003e\n\u003cli\u003ePower supply rectifier: GZ34 (tube)\u003c\/li\u003e\n\u003cli\u003eTHD: below 0.03% (1 kHz, 0 dBFS)\u003c\/li\u003e\n\u003cli\u003eDynamic range: 112 dB (AES17)\u003c\/li\u003e\n\u003cli\u003eFrequency response: 8 Hz – 80 kHz ±1 dB\u003c\/li\u003e\n\u003cli\u003eUSB input: PCM 44.1–384 kHz, DSD64\/128\/256\/512\u003c\/li\u003e\n\u003cli\u003eAES\/EBU, S\/PDIF, ADAT inputs: PCM 44.1–192 kHz\u003c\/li\u003e\n\u003cli\u003eBluetooth: PCM 44.1–96 kHz\u003c\/li\u003e\n\u003cli\u003eRCA output: 2.5 V RMS (unbalanced)\u003c\/li\u003e\n\u003cli\u003eXLR output: 5 V RMS (balanced)\u003c\/li\u003e\n\u003cli\u003ePower consumption: 45 W\u003c\/li\u003e\n\u003cli\u003eEnclosure: 3 mm CNC aluminium, 380 × 290 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 6 kg\u003c\/li\u003e\n\u003cli\u003eManufactured in Poland\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"IGS Audio","offers":[{"title":"Default Title","offer_id":54001640112465,"sku":"60249","price":2477.86,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/IGSAudioDACO1.jpg?v=1781176010","url":"https:\/\/wrdtunes.com\/en-fr\/products\/igs-audio-daco","provider":"Wired Tunes","version":"1.0","type":"link"}
