The output transformer secondary winding provides an alternative phase to compose a balanced output from a single-ended circuit, both single-ended and balanced headphone outputs are genuine transformer outputs rather than conversions.

Three impedance settings selected by front panel switch: Low (8 to 64 ohms), Mid (65 to 250 ohms), High (251 to 600 ohms), separate output transformer windings per setting for optimal impedance matching. Three headphone outputs: 4-pin XLR balanced (high power), 4.4mm balanced, and 6.35mm single-ended. Two analog inputs: balanced XLR and single-ended RCA.

Eight pairs of power transistors provide robust drive and current delivery. Two custom 50W audio-grade toroidal transformers, one dedicated per channel, for minimal inter-channel interference and a genuinely dual-mono power architecture. Matrix relay volume control ensures matched attenuation across all four channels simultaneously without channel imbalance at any setting. High-speed, low-noise rectifiers and four Nichicon capacitors for main filtering. Two LME49720 dual op-amps in the preamplifier section for seamless switching between headphone and preamplifier use. Headphone amplifier can be switched off independently for pure preamplifier operation. Two gain settings: Low gain for IEMs and sensitive headphones, High gain for full-sized over-ear designs. Three headphone outputs: 6.35mm single-ended, 4.4mm balanced, 4-pin XLR balanced. Preamplifier outputs: XLR balanced and RCA unbalanced (both 100 ohm output impedance). Inputs: 1x RCA, 2x XLR balanced. Remote control.

The noise floor is essentially unmeasurable at 0.03% THD, which makes it equally at home with sensitive IEMs on low gain and demanding planars that need the full 4.5 watts.\u003c\/p\u003e\n\u003ch3\u003eBuild and Finish\u003c\/h3\u003e\n\u003cp\u003eHeavy-gauge matte chassis with tactile mechanical switching and a front-panel VU meter that gives the Sunstone a warm visual character alongside its technical precision.

A 10MHz external clock input on BNC lets you connect a dedicated reference such as the Aune XC1 for further refinement. Digital inputs cover USB (32bit\/768kHz, DSD512), coaxial (24bit\/384kHz, DoP128), and optical (24bit\/192kHz, DoP64). The amplifier is an upgraded version of Aune's classic B1 fully discrete circuit, and four Aune-developed filter and drive modes replace the stock chip filters.

It combines decoding up to 32bit\/768kHz PCM and native DSD512 with a fully discrete amplifier and Aune's own clock technology, then lets a phone or tablet connect directly over Bluetooth.

A 10MHz external clock input on BNC allows a dedicated reference clock such as the Aune XC1 to be connected. Wired digital inputs cover USB (32bit\/768kHz, DSD512), coaxial (24bit\/384kHz, DoP128), and optical (24bit\/192kHz, DoP64), and the high-resolution Bluetooth input supports the LDAC, aptX HD, and AAC codecs. The amplifier is an upgraded version of Aune's classic B1 fully discrete circuit, and four Aune-developed filter and drive modes replace the stock chip filters, with an ALPS potentiometer for volume.\u003c\/p\u003e\u003ch3\u003eSound Character\u003c\/h3\u003e\u003cp\u003eThe X1s GT BT is tuned to be musical and smooth while staying resolving.

The amplifier is entirely discrete, using twin JFET transistors at the input stage and a linear power supply to deliver up to 5W, fed by a 50W toroidal low-ripple transformer. Two tuning modes, a standard low-latency mode and a pure-music mode, adjust the clock and filter behavior, and a built-in display shows status at a glance.

A dual DAC arrangement, a second-generation ultra-low-jitter clock core, and a fully discrete amplifier rated at 5W let it decode the highest-resolution files and drive all but the most extreme headphones with ease, while a phone or tablet can now feed it directly over Bluetooth. For the listener building an end-game desktop chain who also wants wireless convenience, the S9c Pro BT is built to be the heart of the system.\u003c\/p\u003e\u003ch3\u003eType and Technology\u003c\/h3\u003e\u003cp\u003eAt its core sit two ESS ES9068A DAC chips operating in clock-synchronized mode, supporting 32bit\/768kHz PCM, native DSD512, and 16x MQA decoding. Aune's second-generation PLL clock core, developed over roughly four years, feeds ultra-low-jitter clock signals to the USB XMOS receiver, the SPDIF path, and the DAC simultaneously, and a 10MHz external clock input allows a dedicated reference clock to be added. The high-resolution Bluetooth receiver supports LDAC, aptX HD, aptX, AAC, and SBC, and it too is synchronized by the ultra-low-jitter clock. The amplifier is entirely discrete, using twin JFET transistors at the input stage and a linear power supply to deliver up to 5W, fed by a 50W toroidal low-ripple transformer. Two tuning modes, a standard low-latency mode and a pure-music mode, adjust the clock and filter behavior, and a built-in display shows status at a glance. Wired inputs include USB, coaxial, optical, and AES, with three headphone outputs on 6.35mm single-ended, 4.4mm balanced, and 4-pin XLR balanced.\u003c\/p\u003e\u003ch3\u003eSound Character\u003c\/h3\u003e\u003cp\u003eThe S9c Pro BT is voiced for clean, precise, and natural sound with the composure that comes from serious clock and power engineering. The dual-DAC layout and low-jitter core produce a deep, quiet backdrop with excellent resolution, while the discrete 5W amplifier brings weight and control to demanding loads. The standard mode delivers neutral, fast, low-latency playback, while the pure-music mode trades a little latency for higher clock precision, greater density, and a more expansive soundstage.

A Twin JFET input stage provides a smooth, tube-like character, while a JRC R2R electronic volume chip forms a four-channel balanced volume control for precise tracking and channel balance. Two selectable Class-A current levels (A-L 50mA and A-H 100mA per transistor) and two gain levels let you match the amplifier to sensitive IEMs or power-hungry full-size headphones. A built-in temperature sensor automatically switches to the lower current mode if the chassis reaches around 69C to protect the amplifier while preserving sound quality.

Its input stage uses a Twin JFET design with two junction field effect transistors in parallel, a topology with voltage controlled behaviour similar to a vacuum tube that gives the signal a full, solid texture from the very first gain stage. A new split power architecture runs the preamplifier stage on high voltage rails of plus or minus 20 V for generous dynamic headroom, while the output stage runs on plus or minus 15 V rails to keep heat in check during extended Class A operation. The output stage places three pairs of power transistors in parallel per channel, lowering output impedance and sharpening transient response, and delivers up to 11,500 mW into 32 ohms. Two selectable current modes set the output stage bias, trading running temperature for a deeper Class A envelope, and combine with four gain settings to create a finely graded power range. A 99 step R2R electronic volume system built on the JRC MUSES72323 chip keeps all four channels precisely matched.\u003c\/p\u003e\n\u003ch3\u003eSound Character\u003c\/h3\u003e\n\u003cp\u003eThe A17 carries Aune's signature warm and refined tonal character into flagship territory. The Twin JFET input lends instruments solid physical presence with a fine luster, while vocals come through delicate, refined and emotionally engaging. Enormous headroom translates into effortless dynamics, firm bass control and a stable, spacious soundstage even in dense passages. With a noise floor of 7 microvolts or lower and THD plus noise of just 0.00045 percent, it stays completely silent behind sensitive in ear monitors yet has the reserves to wake up the hardest loads.\u003c\/p\u003e\n\u003ch3\u003eBuild and Features\u003c\/h3\u003e\n\u003cp\u003eA thick pure aluminium chassis with multi layer heat dissipation channels spreads warmth evenly for stable long term Class A operation, dressed in a sharp mecha inspired industrial design. Power comes from isolated dual supplies: a 100 W linear toroidal transformer feeds the analogue section while a separate supply with digital isolators runs the control logic, backed by an 80,000 uF capacitor bank. Dual colour coded displays show volume, gain and status at a glance, and every function has its own button: standby, mute, input, output, gain and current mode, all mirrored on the solid aluminium remote control.
