Each model has its own character, its own sonic signature. That’s why we’ve created a headphone amp that lets you choose from four different output impedances (two outputs each of 0.1, 33, 82 and 120 ohms) to experience a sound that best suits you and your headphones.\r\n\u003cbr\u003e\u003cbr\u003e\r\n\r\nThe AT-HA5050H is a hybrid Hi-Res Audio headphone amplifier – hybrid because it employs a pair of tubes at the preamp stage and transistors at the power amp stage. Having tubes in the preamp adds warmth and depth to the music, while the bipolar transistors provide distortion-free Class A amplification that is powerful enough to drive headphones of varying impedances without any problem. To further optimize power supply in the amplifier, each part of the amplifier is fed by individual power supply units with fast recovery diodes and regulating circuitry.\r\n\u003cbr\u003e\u003cbr\u003e\r\n\r\nThe AT-HA5050H is equipped with two analog inputs (L\/R RCA line jacks and L\/R balanced XLR jacks) and two digital inputs (S\/PDIF digital coaxial input and USB input with selectable Asynchronous and Adaptive modes). The state-of-the-art DAC is optimized to be compatible with digital audio formats up to PCM 32-bit\/384 kHz and DSD128. Additional features include classic analog VU meters with VU range selector switch, large volume control knob, and an input attenuator switch. \r\n\u003cbr\u003e\u003cbr\u003e\r\n\r\n\u003cb\u003eSpecifications\u003c\/b\u003e\r\n\u003cbr\u003e\r\nSystem Requirements:\tComputer with a USB 2.0 port\r\n\u003cbr\u003e\r\nCPU: Intel Core2 CPU 2.2 GHz or equivalent\r\n\u003cbr\u003e\r\nRAM: 32-bit OS 2 GB or more, 64-bit OS 4 GB or more\r\n\u003cbr\u003e\r\nCompatible OS:\tWindows 7, Windows 8, Windows 8.1, Mac OS X10.9\r\n\u003cbr\u003e\r\nType: Preamplifier stage: vacuum circuit Power amplifier stage: Class A bipolar transistor amplifier\r\n\u003cbr\u003e\r\nCorresponding Headphone Impedance:\t16 – 600 ohms\r\n\u003cbr\u003e\r\nMaximum Output Level: 2,000 mW + 2,000 mW (16 ohms load)\r\n\u003cbr\u003e\r\n 1,000 mW + 1,000 mW (32 ohms load) \r\n\u003cbr\u003e\r\n 500 mW + 500 mW (64 ohms load)\r\n\u003cbr\u003e\r\n 62 mW + 62 mW (600 ohms load)\r\n\u003cbr\u003e\r\nRated Output (20 Hz – 20 kHz):\t125 mW + 125 mW (16 ohms load)\r\n\u003cbr\u003e\r\n \t62 mW + 62 mW (32 ohms load) \r\n\u003cbr\u003e\r\n \t31 mW + 31 mW (64 ohms load)\r\n\u003cbr\u003e\r\n \t3.3 mW + 3.3 mW (600 ohms load)\r\n\u003cbr\u003e\r\nFrequency Response (Line Input): 5 Hz – 200 kHz (0, -1 dB at 32 ohms 10 mW output)\r\n\u003cbr\u003e\r\nFrequency Response (XLR Input): 5 Hz – 200 kHz (+0.5, -2 dB at 32 ohms 10 mW output)\r\n\u003cbr\u003e\r\nTotal Harmonic Distortion: \u0026lt;=0.08% (20 Hz - 20 kHz at 32 ohms 10 mW output)\r\n\u003cbr\u003e\r\nGain: 14 dB (line input); 13.5 dB (XLR input)\r\n\u003cbr\u003e\r\nSignal-to-noise Ratio\t104 dB (A-weighted)\r\n\u003cbr\u003e\r\nSeparation Between Channels: 70 dB (1 kHz at 32 ohms)\r\n\u003cbr\u003e\r\nInput Connector:\tAnalog: Line input (RCA) x 2; XLR connector x 2\r\n\u003cbr\u003e\r\nDigital: \r\n\u003cbr\u003e\r\nUSB (Type B):\r\n\u003cbr\u003e\r\nAsynchronous mode: \r\n\u003cbr\u003e\r\nDSD128 (5.6448 MHz), DSD64 (2.8224 MHz): 24 – 32 bit\r\n\u003cbr\u003e\r\nPCM 384 kHz, 352.8 kHz, 192 kHz, 176.4 kHz, 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz, 32 kHz: 16 – 32 bit\r\n\u003cbr\u003e\r\nAdaptive mode: \r\n\u003cbr\u003e\r\nDSD incompatible\r\n\u003cbr\u003e\r\nPCM 192 kHz, 176.4 kHz, 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz, 32 kHz: 16 – 32 bit\r\n\u003cbr\u003e\r\nDigital coaxial (S\/PDIF) x 1\r\n\u003cbr\u003e\r\nPCM 192 kHz, 176.4 kHz, 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz, 32 kHz: 16 – 24 bit\r\n\u003cbr\u003e\r\nOutput Connector:\t6.3 mm (1\/4\") standard stereo jack (output impedance 0.1 ohms) × 2\r\n\u003cbr\u003e\r\n6.3 mm (1\/4\") standard stereo jack (output impedance 33 ohms) × 2\r\n\u003cbr\u003e\r\n6.3 mm (1\/4\") standard stereo jack (output impedance 82 ohms) × 2\r\n\u003cbr\u003e\r\n6.3 mm (1\/4\") standard stereo jack (output impedance 120 ohms) × 2\r\n\u003cbr\u003e\r\nDA Convertor: \tFrequency response: 5 Hz – 100 kHz (0, -1.5 dB)\r\n\u003cbr\u003e\r\n\t\tTotal harmonic distortion: \u0026lt;=0.0006% (20 Hz - 20 kHz)\r\n\u003cbr\u003e\r\n\t\tSignal-to-noise ratio: 113 dB (A-weighted, 1 Vrms output)\r\n\u003cbr\u003e\r\n\t\tSeparation between channels: 110 dB (20 Hz - 20 kHz)\r\n\u003cbr\u003e\r\nInput Attenuator: -12 dB\r\n\u003cbr\u003e\r\nVU Meter: Range 0 dB, -10 dB, -20 dB, -30 dB\r\n\u003cbr\u003e\r\nPower Supply\t100 – 120V AC or 220 – 240V AC, 50\/60Hz\r\n\u003cbr\u003e\r\nPower Consumption: 53 W (max)\r\n\u003cbr\u003e\r\nDimensions (excluding protrusions): 100 mm (3.9\") H × 332 mm (13.1\") W × 327 mm (12.9\") D\r\n\u003cbr\u003e\r\nWeight:\t 11.0 kg (24.3 lbs.)\r\n\u003cbr\u003e\r\nAccessories Included: Power cable \r\n\u003cbr\u003e","brand":"Audio-Technica","offers":[{"title":"Default Title","offer_id":46949466931375,"sku":"AT-HA5050H","price":1799.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/5277\/2783\/files\/54f89cd51c608315a03aa26fa9aef1ad.webp?v=1779422105"},{"product_id":"hpa-kg-naru-audio-technica-hpa-kg-naru","title":"HPA-KG NARU","description":"\u003c!-- Add Short Description --\u003e\n                                        \u003cp\u003eSince our founding in 1962, we have sought to expand the limits of audio technology, pursuing an ever-changing purity of sound to foster human connections. Still, after six decades of discovery and innovation we felt it was time to take our analog audio exploration to an even higher level. The NARUKAMI series offers premium, boundary-pushing audio experiences, along with the meticulous Japanese craftsmanship that is an Audio-Technica hallmark.\u003c\/p\u003e\r\n\u003cp\u003eTaking its name from the thunder god of Japanese legend, the NARUKAMI series features high-end audio products designed to ignite elemental passions. Our engineers rely on their refined auditory judgment, rather than a sterile set of technical specifications, to assess sound quality, while key materials, like precious KUROGAKI wood, are selected to bring the listener closer to the wonders of nature.\u003c\/p\u003e\u003cp\u003eThe top of the HPA-KG NARU tube amplifier\/preamplifier is stylized like a dry landscape garden (karesansui), representing water flows that run down along the amplifier’s unique KUROGAKI wood side panels. The metal mesh cover protecting the vacuum tubes and output transformers recalls the dense pattern of the Ayasugi tree’s flat needles. These visual nods to nature prefigure the lifelike sound that awaits the listener.\u003c\/p\u003e\r\n\u003cp\u003eThe NARUKAMI headphone amplifier employs a fully balanced drive design, and all of the unit’s vacuum tubes are individually tested and matched to ensure optimal performance. The signal amplification stage uses a shunt regulated push-pull (SRPP) circuit design and employs paired JJ ECC83S tubes, known for their rich and resonant sound characteristics. In the power stage, two pairs of Takatsuki TA-300B tubes are utilized, delivering powerful driving force and dynamic high-quality sound.\u003c\/p\u003e\r\n\u003cp\u003eThe amplifier’s independent signal circuit and power supply for L\/R channels ensure high separation and low noise, delivering transparent and rich sound quality for discerning audio enthusiasts. The amorphous core silver wire output transformer from Lundahl, chosen for its low magnetic hysteresis loss and optimal impedance matching, adds richness to the sound and provides flexibility with a headphone matching circuit.\u003c\/p\u003e\r\n\u003cp\u003eBut the NARUKAMI amplifier is not just a headphone amplifier; it also serves as a preamplifier with unbalanced RCA and balanced XLR pre-outs. The preamp is designed to amplify low-level audio signals from a source component, producing warm, natural sound from the vacuum tubes and bringing it to a level suitable for driving a power amplifier. The amplifier is also equipped with one set of unbalanced RCA line inputs and two pairs of balanced XLR inputs to allow connection of a CD\/DVD player and other audio devices.\u003c\/p\u003e\r\n\u003cp\u003eThe HPA-KG NARU features two headphone jacks on the front of the unit: a 4.4 mm 4-pin XLR balanced jack for optimal channel separation, and a standard 6.3 mm (1\/4\") jack. An impedance selector switch allows you to choose the appropriate impedance (32–80 ohms, 80–250 ohms, 250–600 ohms) based on the characteristics of your headphones and desired sound quality.\u003c\/p\u003e\r\n\u003cp\u003eTo complement this high-performance amplifier we include a pair of our limited-edition AW-KG NARU headphones, featuring housings crafted from precious KUROGAKI wood.
