High-end audio is a bit like haute couture: ruled by legacy names, soaked in ritual, and occasionally, gloriously disrupted by someone who didn’t get the memo. Luxsin, backed by the same minds behind Eversolo and Zidoo, arrives with the audacity to shake things up and the experience to back it. Their latest creation, the X9, isn’t just another DAC/amp hybrid. It’s a calculated affront to complacency.

Power That Laughs in Ohms

Let’s get one thing out of the way: the Luxsin X9 has power. The kind of power that could probably jump-start a small electric vehicle. It’s rated for 6000mW into 16Ω and 3000mW into 32Ω from its balanced output—impressive numbers that show just how much current this amp can push when pushed hard. While 16Ω is more of a lab benchmark than a headphone you’re likely to use, 32Ω is where real-world listening happens, and the X9 handles it with effortless control and headroom to spare. From low-impedance closed-backs to power-hungry planar magnetics, it doesn’t blink. Inside, it’s a greatest-hits album of componentry: OPA1612 op-amps, TPA6120A2 current-feedback amps, and something called Dynamic Negative Feedback (DNF), which sounds like a cult but actually murders distortion in cold blood.

Volume control is handled by a fully balanced R2R ladder with 0.1dB channel-matched precision. Translation? No more digital volume weirdness where your music turns into a ghost whisper at low levels.

Digital Decoding Without the Drama

The X9’s DAC is AKM’s finest—the AK4499EX, paired with its AK4191EQ modulator sidekick. This duo, along with an XMOS XU316 USB interface and femtosecond Accusilicon clock (because milliseconds are for peasants), delivers numbers so low on distortion they practically register as moral purity. PCM up to 32-bit/768kHz and DSD512 are on the menu. Also onboard: the AK7739 DSP chip, which fuels something genuinely cool.

HP-EQ: The Smartest Trick in the Room

HP-EQ isn’t your dad’s bass boost button. It’s a real-time, hardware-level EQ engine that analyzes your headphones and adjusts them to follow the Harman target curve—a frequency response so universally agreeable it might as well be the audio equivalent of Helvetica. With over 2,500 headphone profiles supported and customizable presets for the control freaks, it makes EQing idiot-proof without treating you like one.

Looks That Could Kill (Interference)

Machined from CNC aluminum and set at a rakish angle like a Bond villain’s recliner, the X9 has presence. Its 4.0-inch 1080P touchscreen is quick, intuitive, and refreshingly devoid of design crimes. Running on a custom RTOS, the UI is all slick gestures and customizable VU meters. Inside, a star-shaped voltage distribution system ensures that noise and crosstalk are things other, lesser amps deal with.

Ports Galore: The I/O of Your Dreams

This thing doesn’t just connect—it commits. Digital inputs include USB-B, USB-C, Optical, Coax, HDMI ARC, and Bluetooth 5.0 with SBC and AAC (aptX snobs, keep walking). Analog in? RCA. Outputs? Balanced XLR, unbalanced RCA, dual sub outs. Headphone jacks? Every flavor: 6.35mm single-ended, 4.4mm balanced, and XLR 4-pin balanced. There’s even smart impedance detection, which means it does the gain-setting guesswork for you.

Final Verdict: The Needle Has Moved

The Luxsin X9 is not trying to fit in. It’s not hoping you’ll mistake it for a FiiO, or wonder if it’s Schiit with a face lift. It’s here to throw elbows, to challenge your assumptions, and maybe, just maybe, make you question why you’ve been babying that underpowered brick you call a DAC.

In a sea of spec-sheet braggarts and feature-bloated Frankenamps, the X9 is something scandalously rare: a product that delivers, surprises, and dares to be better.

Imagine that.
