That long, controlled stroke is the point of the whole design. Bass arrives with real physical presence, big dynamic swings stay composed, and music opens up the way it does from a good pair of loudspeakers.\u003c\/p\u003e\n\u003cp\u003eThe AR9000 sits at the top of Aune's Air Reference Series, the line that made Aune a serious name in open-back headphones. It is built for listeners who want speaker-scale sound at a desk or in a listening chair: put on jazz, orchestral, or electronic music and it answers with weight, air, and space.\u003c\/p\u003e\n\u003ch3\u003eDynamics You Can Feel\u003c\/h3\u003e\n\u003cp\u003eMost headphones shrink the distance between a drum hit and the quiet around it. The AR9000 keeps that contrast intact. Kick drums land with a small pulse of moving air, bass lines reach into the lowest octave without smearing, and crescendos grow instead of simply getting louder. Aune rates the frequency range at 4Hz to 50,000Hz, and the low end is the first thing most listeners notice.\u003c\/p\u003e\n\u003cp\u003eTonally, the AR9000 stays balanced rather than boosted. In \u003ca href=\"\/blogs\/features\/about-to-shake-things-up-aune-ar9000-ar3000-first-impressions\" target=\"_blank\" title=\"Aune AR9000 and Aune AR3000 First Impressions from Vienna High-End 2026\" rel=\"noopener\"\u003eour first impressions\u003c\/a\u003e, our review team called it one of the most normal sounding headphones they heard at its debut, and meant it as high praise: vocals sit exactly where they should, and the crucial 1kHz to 2kHz midrange region is filled in rather than scooped out.\u003c\/p\u003e\n\u003ch3\u003eA Driver Built Like a Miniature Loudspeaker\u003c\/h3\u003e\n\u003cp\u003eThe punch comes from engineering borrowed from high-end speaker design. Aune's Omni-Stack Carbon Diaphragm layers continuous carbon fibers at precise angles with no cross-weave, so the driver is extremely stiff for its weight and resists the flexing that blurs fine detail. Zone-specific heat treatment then tunes damping across different areas of the diaphragm's surface.\u003c\/p\u003e\n\u003cp\u003eAune's patented Constant-Flux magnetic circuit keeps drive force consistent through the full 4mm stroke, while a new high-damping suspension with radial stiffeners holds that motion piston-straight. Behind the driver, a patented absorption and diffusion structure routes reflected energy through precisely shaped open and closed cavities instead of letting it wash back through the music. The audible result is distortion under 0.03% at 1kHz, fast clean transients, and separation that holds together when a mix gets dense.\u003c\/p\u003e\n\u003ch3\u003eAn Open Stage, Angled Like Speakers\u003c\/h3\u003e\n\u003cp\u003eOpen-back means the earcups are acoustically open to the room, which trades isolation for a natural sense of space. The AR9000 leans into this with Aune's Tilted Acoustic Matrix: each driver is angled so sound arrives at your ear the way it would from a speaker placed in front of you, not fired straight into the ear canal. Highly breathable mesh in both the front and rear chambers lets air and acoustic energy move freely through the housing.\u003c\/p\u003e\n\u003cp\u003eThe result is a wide, naturally layered stage with precise image placement and none of the pressure buildup that makes long sessions tiring. Like every open-back headphone, the AR9000 does not block outside noise and does not keep your music private, so it belongs in a quiet room rather than on a commute.\u003c\/p\u003e\n\u003ch3\u003eBuilt for Long Sessions\u003c\/h3\u003e\n\u003cp\u003eAt roughly 430g, the AR9000 is a substantial headphone, and the fit is designed around that fact. A wide suspension headband spreads the weight across the top of the head instead of concentrating it at one point, and the breathable earpads keep air moving around your ears so heat never becomes the reason a session ends.\u003c\/p\u003e\n\u003cp\u003eThe headband assembly is all metal, and the floating frame carries the precision-machined lines of the Air Reference Series. A deep metallic finish and honeycomb acoustic grille give the AR9000 a restrained look that matches how it sounds: controlled, confident, and built to be kept for years.\u003c\/p\u003e\n\u003ch3\u003eEasy to Drive, Every Plug Included\u003c\/h3\u003e\n\u003cp\u003eWith a 43 ohm impedance and 102dB sensitivity, the AR9000 is easy to drive by flagship standards. It reaches satisfying volume from modest sources, and a good desktop DAC and amplifier give its dynamics room to stretch.\u003c\/p\u003e\n\u003cp\u003eThe included 1.6m cable uses eight strands of high-purity silver-plated OCC copper and ends in an interchangeable plug system covering 3.5mm and 6.35mm single-ended along with 4.4mm and XLR balanced connections. One cable moves between a laptop, a desktop rig, and a balanced amplifier.

Our first listen left us calling the AR9000 the punchier alternative: its midrange is more filled in, its bass carries more weight, and it trades some of the HD 800 S's diffuse, panoramic staging for a more focused, closer presentation. At 43 ohms it is also far easier to drive than the 300 ohm Sennheiser.\u003c\/p\u003e\n\u003cp\u003eWithin Aune's own lineup, the AR9000 stands above the \u003ca href=\"https:\/\/headphones.com\/products\/aune-ar5000-mk2-headphones\" target=\"_blank\" title=\"Aune AR5000 Mk2 Headphones | Headphones.com\" rel=\"noopener\"\u003eAR5000 MK2\u003c\/a\u003e, the headphone that earned Aune its open-back reputation on tonal balance alone.

Those two numbers are the story in miniature: enough power for the most demanding planar magnetic headphones made, and a background quiet enough for sensitive in-ear monitors.\u003c\/p\u003e\n\n\u003cp\u003eThe S17 Pro EVO is the amplifier half of a serious desktop system. There is no DAC inside, by design: connect any DAC or streamer through RCA or balanced XLR and it handles everything downstream, driving headphones from three front-panel outputs or acting as the preamp for powered speakers. It replaces the S17 Pro at the top of Aune's amplifier line, keeping the same Class A circuit and adding the usability the original lacked.\u003c\/p\u003e\n\n\u003ch3\u003eClass A, and Why It Runs Warm\u003c\/h3\u003e\n\n\u003cp\u003eClass A means the output transistors conduct at full current all the time, whether music is playing or not. Because the transistors never switch off, the design avoids crossover distortion entirely and stays in its most linear operating region at every volume. The sound this topology is known for is warm, smooth, and dense, with low-level detail that stays refined as the level climbs.\u003c\/p\u003e\n\n\u003cp\u003eConstant current means constant heat, and the S17 Pro EVO manages it honestly. Two selectable current modes set the character: A-L runs 100mA per channel for everyday listening, while A-H doubles it to 200mA for maximum current reserve and the fullest presentation. Heatsinks, a bottom heat plate, and the chassis itself form one integrated cooling structure vented through the rear panel, and if the internal temperature reaches 69C the amplifier steps itself back to A-L automatically. It is built to run warm; give it some breathing room and it will hold stable Class A operation all day.\u003c\/p\u003e\n\n\u003ch3\u003eTwin JFETs In, 16 Transistors Out\u003c\/h3\u003e\n\n\u003cp\u003eAune builds the input stage around matched twin JFET transistors. JFETs combine very high input impedance with a naturally smooth transfer characteristic, which is why their sound is so often compared to vacuum tubes. Using two thermally matched devices keeps the circuit's midpoint voltage stable as the amplifier warms up, so the tube-like richness stays consistent from cold start to hour three.\u003c\/p\u003e\n\n\u003cp\u003eThe output stage uses two parallel pairs of transistors per channel, 16 output transistors in total across the balanced circuit, fed by a 50 watt low-ripple toroidal transformer and a 19,200uF capacitor bank. Power for the digital control circuitry is kept separate from the analog supply so the audio path stays free of interference. The measured result is 0.00024% THD+N at 1kHz, vanishingly low distortion for a high-current Class A design.\u003c\/p\u003e\n\n\u003ch3\u003ePower for the Hardest Headphones on the Wall\u003c\/h3\u003e\n\n\u003cp\u003eInefficient planar magnetic headphones like the \u003ca href=\"\/products\/hifiman-susvara-flagship-headphones\" title=\"HiFiMAN Susvara Flagship Headphones\" target=\"_blank\" rel=\"noopener\"\u003eHIFIMAN Susvara\u003c\/a\u003e are the reason amplifiers like this exist. The S17 Pro EVO delivers 7,500mW into 32 ohms and nearly 3 watts into 90 ohms from its balanced outputs, real current reserves for headphones that starve on smaller desktop amps. High-impedance dynamics are covered too: 908mW into 300 ohms is far more than a \u003ca href=\"\/products\/sennheiser-hd-800-s-dynamic-headphones\" title=\"Sennheiser HD 800 S Headphones\" target=\"_blank\" rel=\"noopener\"\u003eSennheiser HD 800 S\u003c\/a\u003e will ever ask for.

Low gain pairs finer volume steps with the roughly 3.6uV noise floor so IEMs and efficient headphones stay hiss-free, while high gain opens up the full 7.5 watts. Headphones connect through 4-pin XLR balanced, 4.4mm balanced, or 6.35mm single-ended outputs on the front panel.\u003c\/p\u003e\n\n\u003ch3\u003eVolume You Can Trust at Whisper Levels\u003c\/h3\u003e\n\n\u003cp\u003eVolume is handled by a four-way balanced R2R resistor network built around a JRC volume chip with dedicated op-amps. Unlike a conventional potentiometer, which drifts out of balance at the bottom of its range, the R2R control keeps left and right channels matched at exactly the low levels where late-night listening happens, and it preserves staging and image placement while doing it.\u003c\/p\u003e\n\n\u003cp\u003eDay-to-day control is simple: one multifunction knob adjusts volume, gain, and current mode, and a 4-inch display shows input, gain, mode, volume, and internal temperature at a glance. The interface shifts between blue for A-L and red for A-H so you always know how hard the amp is running, an automatic screen-off option keeps the desk dark, and the all-aluminum remote handles everything from the couch.\u003c\/p\u003e\n\n\u003ch3\u003eA Preamp When the Headphones Come Off\u003c\/h3\u003e\n\n\u003cp\u003eThe S17 Pro EVO doubles as a proper analog preamp. Headphone and preamp operation are selected independently, and each mode remembers its own volume setting, so switching from headphones to powered speakers does not start with a lunge for the knob. Balanced XLR and RCA preamp outputs feed active monitors or a power amplifier, and two line inputs let a balanced DAC and a second source stay connected at once.\u003c\/p\u003e\n\n\u003cp\u003eIn an all-Aune stack it is the natural partner for the \u003ca href=\"\/products\/aune-ar9000-headphones\" title=\"Aune AR9000 Headphones\" target=\"_blank\" rel=\"noopener\"\u003eAR9000 flagship open-back\u003c\/a\u003e, with the balanced power and Class A control to show what that 50mm carbon fiber driver can do.

The component count rises from 635 to 657, while the fully discrete Class A architecture, twin JFET input, and 7.5 watt balanced output stage carry over intact.\u003c\/p\u003e\n\n\u003cp\u003eAt $799, the S17 Pro EVO makes a simple case: genuine high-current Class A sound, enough clean power for any headphone in the store, and preamp flexibility that lets one box anchor both your headphone and

Audio YUKI Portable DAC and Headphone Amplifier","description":"\u003cp\u003eThe Aune Audio Yuki is a portable USB DAC and headphone amplifier built around a choice almost nothing else in the dongle category makes: a fully discrete balanced amplifier with 16 transistors, the kind of output stage normally reserved for desktop gear. Aune then puts the analog board on display through a glass window in the snow-white aluminum shell, so the engineering is also the design.\u003c\/p\u003e\n\u003cp\u003eYuki connects over USB-C to smartphones, tablets, laptops, and Nintendo Switch, and feeds IEMs or headphones through 3.5mm single-ended and 4.4mm balanced outputs. It is made for listeners who want their in-ear monitors to sound like they are plugged into a serious system, wherever the music actually happens.\u003c\/p\u003e\n\u003ch3\u003eA Desktop Amp Idea in a Pocket Device\u003c\/h3\u003e\n\u003cp\u003eMost compact USB DACs combine conversion and amplification into a single highly integrated chip, because space and USB power leave little room for anything else. Aune splits the Yuki into two stacked boards instead: one layer for USB input and digital-to-analog conversion, one dedicated entirely to the analog amplifier. The amp layer carries 16 discrete transistors arranged as four independent amplification paths.\u003c\/p\u003e\n\u003cp\u003eA dual-boost converter generates positive and negative 5V rails for that amplifier, giving it more voltage headroom than a circuit running straight off standard USB power. The analog board is built on a hybrid ceramic PCB, chosen for its thermal conductivity, insulation, and low dielectric loss, which helps the circuit stay consistent and preserves fine high-frequency detail.\u003c\/p\u003e\n\u003ch3\u003eTwo DAC Chips, One Per Channel\u003c\/h3\u003e\n\u003cp\u003eYuki uses two Cirrus Logic CS43198 DAC chips with one dedicated to each channel, so left and right are converted on completely independent paths. Keeping the channels separate improves stereo separation and dynamics, which is exactly what preserves the sense of instruments occupying distinct places in a recording.\u003c\/p\u003e\n\u003cp\u003ePlayback support covers PCM up to 32-bit\/768kHz and DSD256, with Hi-Res Audio certification. Lossless streaming from a phone, a high-resolution library on a laptop, and DSD files all stay within what the hardware can decode natively.\u003c\/p\u003e\n\u003ch3\u003eQuiet Enough for the Most Sensitive IEMs\u003c\/h3\u003e\n\u003cp\u003eSensitive in-ear monitors reveal amplifier noise as a constant background hiss, so a portable DAC lives or dies by its noise floor. The Yuki measures approximately 2.9 microvolts of output noise with THD+N of 0.00033% at 1kHz, quiet enough that reverb tails, room sound, and positional cues sit against silence instead of static.\u003c\/p\u003e\n\u003cp\u003eThe 4.4mm balanced output puts all four amplifier paths to work with balanced IEM and headphone cables, while the 3.5mm jack covers standard cables without an adapter. Two hardware buttons handle volume directly on the unit, no companion app required.\u003c\/p\u003e\n\u003ch3\u003ePhone, Laptop, and Nintendo Switch\u003c\/h3\u003e\n\u003cp\u003eConnected to a phone or tablet, Yuki takes over from the device's internal audio with its dual-DAC conversion and discrete amplification. Beside a laptop it works as a compact desk source for after-hours listening. UAC1.0 support means it also works with Nintendo Switch, where the low noise floor and channel separation keep game audio detailed and precisely placed.\u003c\/p\u003e\n\u003cp\u003eYuki is honest about its scope. It is built to make IEMs and efficient headphones sound their best, not to replace a desktop amplifier for power-hungry planars, and within that scope it applies engineering most of the dongle category skips.

It borrows the architecture of much larger amplifiers, twin JFET input stage, R2R volume control, and selectable Class A bias current, and makes that recipe fit a desk where space actually matters.\u003c\/p\u003e\n\u003cp\u003eThe N7 is a pure analog amplifier and preamp with no DAC inside: feed it from any DAC or streamer over RCA or balanced XLR and it takes care of everything after the conversion. For listeners stepping up from a dongle or all-in-one to their first serious amplifier, this is the point where Class A stops being exotic and starts being affordable.\u003c\/p\u003e\n\u003ch3\u003eReal Class A, Warm on Purpose\u003c\/h3\u003e\n\u003cp\u003eClass A means the output transistors conduct continuously instead of switching on and off with the signal, which eliminates crossover distortion and keeps the amplifier in its most linear range at all times. The sound this design is known for is smooth, full-bodied, and naturally warm, and the N7 runs true Class A rather than borrowing the label.\u003c\/p\u003e\n\u003cp\u003eThe input stage uses matched twin JFETs packaged together so both devices heat and behave identically, keeping the circuit's midpoint voltage stable and the character consistent. JFETs are the reason the N7 earns its tube-like description: high input impedance and a naturally smooth transfer characteristic, with none of a tube's fragility or maintenance.\u003c\/p\u003e\n\u003ch3\u003eTwo Current Levels, Two Gain Levels, One Quiet Background\u003c\/h3\u003e\n\u003cp\u003eLike Aune's flagship amplifiers, the N7 offers dual-level Class A bias current: A-L for everyday listening and A-H for a fuller, more forceful presentation, shown in blue or red on the display along with real-time temperature. Two gain settings then match the output to the headphone, from sensitive in-ear monitors on low gain to demanding full-size headphones on high.\u003c\/p\u003e\n\u003cp\u003eBehind that flexibility sits a measured noise floor of 3 microvolts in high gain and THD+N below 0.0004% at 1kHz. In practice, IEMs get silence instead of hiss, and hard-to-drive headphones get 6,570mW into 32 ohms or 750mW into 300 ohms from the balanced output. A full aluminum chassis with side heatsink fins keeps sustained Class A operation stable.\u003c\/p\u003e\n\u003ch3\u003eR2R Volume That Stays Balanced at Night\u003c\/h3\u003e\n\u003cp\u003eThe N7 uses two JRC R2R electronic volume chips with dedicated op-amps, forming a four-channel balanced volume chain. Unlike a conventional potentiometer, which loses left-right balance at the bottom of its range, this control stays matched at the low levels where late-night listening actually happens, and it preserves imaging and stage while doing it.\u003c\/p\u003e\n\u003cp\u003eOne multifunctional knob handles volume, gain, current level, and headphone or preamp switching, with a 3-inch display keeping the current state readable from across the desk. An aluminum remote is included, so the N7 works as well from a couch as it does at arm's reach.\u003c\/p\u003e\n\u003ch3\u003eA Preamp for the Rest of the System\u003c\/h3\u003e\n\u003cp\u003eThe N7 offers two headphone outputs (6.35mm single-ended and 4.4mm balanced), two line inputs (RCA and XLR), and two preamp outputs (RCA and XLR), with an independent Class A preamp function. Plug in powered monitors or a power amplifier and it becomes the control center of a compact desktop system, headphones by night, speakers by day.\u003c\/p\u003e\n\u003cp\u003ePower comes from an external 18V adapter, which keeps AC conversion outside the chassis.

The A17 resolves that tension with a split architecture: the pre-amplification stage runs on higher voltage rails at plus and minus 20V for headroom and stage width, while the output stage runs at plus and minus 15V to keep heat in check without giving up drive.\u003c\/p\u003e\n\u003cp\u003eA 100 watt toroidal transformer powers the analog section exclusively, backed by a filter capacitor bank totaling nearly 80,000uF. The display and control system draw from a separate supply, with control signals isolated through digital isolator chips so nothing from the digital side leaks into the music. The measured floor: under 7 microvolts of output noise and THD+N below 0.0005%.\u003c\/p\u003e\n\u003ch3\u003eTwin JFETs In, a MUSES Chip on the Volume\u003c\/h3\u003e\n\u003cp\u003eThe input stage uses Aune's twin JFET arrangement in dual-transistor parallel configuration. JFETs share voltage-control behavior with vacuum tubes, which is where the A17 gets its natural, layered, warm character; running matched pairs keeps that character stable as the amplifier heats through a long session.\u003c\/p\u003e\n\u003cp\u003eVolume runs through the JRC MUSES72323, a high-end R2R volume chip with 99 steps, synchronizing all four balanced channels to keep left-right imbalance out of the picture even at whisper levels. Headphone and preamp outputs keep independent volume logic, so switching between headphones and powered speakers never starts with a blast at the wrong level.\u003c\/p\u003e\n\u003ch3\u003eFour Gains, Two Currents, Every Headphone Covered\u003c\/h3\u003e\n\u003cp\u003eFour gain settings from 5.8dB to 13.5dB combine with two Class A current modes, A-L and A-H, to match the amplifier's operating point to the load. Sensitive in-ear monitors on G-1 sit on a background quieter than 7 microvolts; flagship over-ears on G-4 get the full output. The dual-color display shows current mode, gain, volume, and internal temperature at a glance, echoed by a second small display on the top panel.\u003c\/p\u003e\n\u003cp\u003eHeat is managed the honest way, with mass and surface area: an ultra-thick pure aluminum chassis with a multi-tiered internal heatsink structure channels warmth away from the circuit and spreads it across the case.

Almost nothing else you can fit in a jacket pocket attempts this.\u003c\/p\u003e\n\u003cp\u003eThe BX2 Magnum is built for listeners who refuse to choose between a serious rig and a portable one. Feed it from a DAP, portable DAC, or desktop source through 3.5mm, 4.4mm balanced, or RCA inputs, and it drives IEMs and full-size headphones from 3.5mm and 4.4mm outputs with a choice of two completely different sonic characters.\u003c\/p\u003e\n\u003ch3\u003eTwo Amplifiers in One Chassis\u003c\/h3\u003e\n\u003cp\u003eA physical switch selects between tube mode and transistor mode, and the two signal paths are fully independent, joined only by latching relays that switch without coloring the signal. Transistor mode is the precision path: linear, fast, and measurably clean at 0.0003% THD+N from the balanced output. Tube mode routes the signal through the Nutubes for the warmth, body, and harmonic richness tubes are loved for, with distortion up to 1% because that character is the entire point.\u003c\/p\u003e\n\u003cp\u003eTwo gain levels and two Class A current settings multiply those characters further. Between mode, gain, and bias, the BX2 Magnum offers eight distinct operating combinations to match headphones and mood.\u003c\/p\u003e\n\u003ch3\u003eReal Tubes, Properly Driven\u003c\/h3\u003e\n\u003cp\u003eThe Korg Nutube 6P1 is a true dual-triode vacuum tube, and in the BX2 Magnum both tubes sit genuinely in the amplification stage rather than glowing decoratively behind a window. A dedicated 30V anode supply pushes them into their optimal linear range, the voltage headroom portable tube stages usually lack. Ahead of them, a twin JFET input stage adds its naturally smooth transfer characteristic, and the fully balanced four-channel layout keeps left and right isolated for precise imaging.\u003c\/p\u003e\n\u003ch3\u003eSeven Batteries, Each with a Job\u003c\/h3\u003e\n\u003cp\u003ePower is the reason the BX2 Magnum sounds like desktop gear. Its 14,000mAh battery bank uses seven independent 2000mAh cells: six form a true plus and minus 12V analog supply feeding the amplifier directly, while the seventh runs the digital control circuits in complete isolation, keeping control noise out of the music. Two four-segment indicators on the rear panel track both banks in real time.\u003c\/p\u003e\n\u003cp\u003eA full charge over USB-C takes about five hours and delivers up to 13 hours in transistor mode or more than 8 hours in tube mode, enough for a work day on the solid-state path or a long evening on the tubes.\u003c\/p\u003e\n\u003ch3\u003eA Desk Mode, Thanks to the BP1\u003c\/h3\u003e\n\u003cp\u003eA five-pin external power input lets the BX2 Magnum bypass its battery entirely and run on plus and minus 15V from Aune's \u003ca href=\"\/products\/aune-audio-bp1-external-power-supply\" title=\"Aune Audio BP1 External Power Supply\" target=\"_blank\" rel=\"noopener\"\u003eBP1 external power supply\u003c\/a\u003e, sold separately and built in the same stackable chassis.

High gain delivers 5,180mW balanced into 32 ohms and 644mW into 300 ohms, so hard planars and high-impedance dynamics both stay on the menu.
