{"product_id":"aune-a17-horlursforstarkare","title":"Aune A17 - Headphone amplifier","description":"\u003cp\u003eThe Aune A17 is a flagship among fully discrete Class A headphone amplifiers, and it works equally well as a preamplifier. Thanks to its separate power supply, precision volume control, and substantial power reserves, it drives everything from sensitive in-ear headphones to the most demanding over-ear models, with stable operation even during long listening sessions.\u003c\/p\u003e\n\u003cp\u003eThe input stage is built around twin-JFET transistors that contribute a natural, warm character reminiscent of tube amplifiers. Two current modes and four gain stages, combined with a 99-step R2R volume control (JRC MUSES72323), let you fine-tune the drive precisely to suit your headphones. The output stage uses three pairs of power transistors in parallel per channel, lowering the output impedance and improving both transient response and bass control.\u003c\/p\u003e\n\u003cp\u003eThe power supply is divided into high- and low-voltage sections: the preamp is supplied with ±20 V for ample dynamic headroom, while the power amp runs at ±15 V for better thermal balance. The analog section is powered by a 100 W toroidal transformer with an 80,000 µF capacitor bank, while the digital control has its own dedicated power supply with digital isolators that shield it from interference. Everything is housed in a sturdy aluminum chassis with multi-layer heatsinks for even heat dissipation.\u003c\/p\u003e\n\u003cp\u003eOn the connection side, you will find 4-pin XLR, 6.35 mm and 4.4 mm headphone outputs, as well as RCA and XLR inputs and outputs, making the A17 equally suitable as a dedicated headphone amplifier or as a preamplifier in a speaker system. All functions are controlled with dedicated buttons and mirrored on the included aluminum remote control.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Fully discrete Class A headphone amplifier and preamplifier\u003c\/li\u003e\n\u003cli\u003eInput stage: Twin-JFET\u003c\/li\u003e\n\u003cli\u003eVolume control: 99-step R2R (JRC MUSES72323)\u003c\/li\u003e\n\u003cli\u003eCurrent modes: 2\u003c\/li\u003e\n\u003cli\u003eOutput stage: 3 pairs of power transistors in parallel per channel\u003c\/li\u003e\n\u003cli\u003ePower supply: Separate ±20 V (preamp) \/ ±15 V (power amp) · 100 W toroidal transformer · 80,000 µF capacitor bank\u003c\/li\u003e\n\u003cli\u003eGain levels: 4 (G-1 = 5.8 dB, G-2 = 9.2 dB, G-3 = 11.6 dB, G-4 = 13.5 dB)\u003c\/li\u003e\n\u003cli\u003eOutput power: max approx. 11.5 W @ 32 Ω (balanced), 2820 mW @ 32 Ω (6.35 mm)\u003c\/li\u003e\n\u003cli\u003eTHD+N: \u0026lt;0.0005 % @ 1 kHz\u003c\/li\u003e\n\u003cli\u003eSNR: \u0026lt;-115 dB @ 32 Ω\u003c\/li\u003e\n\u003cli\u003eChannel separation: \u0026lt;-100 dB @ 1 kHz, 32 Ω\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz-80 kHz, ±0.05 dB\u003c\/li\u003e\n\u003cli\u003eNoise floor: ≤7 µV\u003c\/li\u003e\n\u003cli\u003eHeadphone outputs: 4-pin XLR, 6.35 mm (1 Ω), 4.4 mm (1 Ω)\u003c\/li\u003e\n\u003cli\u003eConnections: RCA and XLR in\/out (input impedance 10 kΩ; preamp output 200 Ω RCA \/ 100 Ω XLR)\u003c\/li\u003e\n\u003cli\u003eDimensions: 345 × 290 × 130 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 17 kg\u003c\/li\u003e\n\u003cli\u003eAccessories: power cable, 6.35 mm to 3.5 mm adapter, aluminum remote control, quick-start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eOutput power per gain level:\u003c\/p\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eLast\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-1 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-2 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-3 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-4 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e32 Ω\u003c\/td\u003e\n\u003ctd\u003e480 \/ 1800 mW\u003c\/td\u003e\n\u003ctd\u003e1050 \/ 3920 mW\u003c\/td\u003e\n\u003ctd\u003e1800 \/ 6840 mW\u003c\/td\u003e\n\u003ctd\u003e2820 \/ 11500 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 Ω\u003c\/td\u003e\n\u003ctd\u003e160 \/ 640 mW\u003c\/td\u003e\n\u003ctd\u003e350 \/ 1370 mW\u003c\/td\u003e\n\u003ctd\u003e610 \/ 3400 mW\u003c\/td\u003e\n\u003ctd\u003e940 \/ 3720 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e150 Ω\u003c\/td\u003e\n\u003ctd\u003e105 \/ 420 mW\u003c\/td\u003e\n\u003ctd\u003e240 \/ 930 mW\u003c\/td\u003e\n\u003ctd\u003e410 \/ 1600 mW\u003c\/td\u003e\n\u003ctd\u003e630 \/ 2480 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e250 Ω\u003c\/td\u003e\n\u003ctd\u003e64 \/ 256 mW\u003c\/td\u003e\n\u003ctd\u003e140 \/ 560 mW\u003c\/td\u003e\n\u003ctd\u003e250 \/ 980 mW\u003c\/td\u003e\n\u003ctd\u003e380 \/ 1520 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e300 Ω\u003c\/td\u003e\n\u003ctd\u003e53 \/ 210 mW\u003c\/td\u003e\n\u003ctd\u003e120 \/ 470 mW\u003c\/td\u003e\n\u003ctd\u003e210 \/ 820 mW\u003c\/td\u003e\n\u003ctd\u003e320 \/ 1260 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e470 Ω\u003c\/td\u003e\n\u003ctd\u003e34 \/ 136 mW\u003c\/td\u003e\n\u003ctd\u003e76 \/ 300 mW\u003c\/td\u003e\n\u003ctd\u003e132 \/ 530 mW\u003c\/td\u003e\n\u003ctd\u003e200 \/ 810 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e600 Ω\u003c\/td\u003e\n\u003ctd\u003e26 \/ 104 mW\u003c\/td\u003e\n\u003ctd\u003e60 \/ 240 mW\u003c\/td\u003e\n\u003ctd\u003e100 \/ 410 mW\u003c\/td\u003e\n\u003ctd\u003e160 \/ 640 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Aune","offers":[{"title":"Default Title","offer_id":57164589564228,"sku":"571645895642","price":26990.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0919\/1306\/0676\/files\/Aune_A17__01_9d3fe898-3dfe-4065-8688-7011d213dc1c.jpg?v=1787923884","url":"https:\/\/www.mychifi.se\/en\/products\/aune-a17-horlursforstarkare","provider":"MYC HiFi","version":"1.0","type":"link"}
