The Luxsin X9 is a DAC, headphone amplifier and preamplifier with a host of exciting features. It comes equipped with a 4-inch colour touch display for easy control, along with Hi-Res Bluetooth for wireless streaming. There is an advanced DSP engine that offers tailored sound profiles for thousands of well-known headphone models, plus R2R-based volume control for precision and refinement. HDMI ARC support rounds out the package, giving you a flexible hub that can slot into both desktop and home media setups with ease.
It is worth noting that Luxsin is a premium audio brand under the Zidoo Group, making it a sister brand to the well-regarded Eversolo. This lineage suggests significant R&D backing and a strong legacy of innovation.
The Luxsin name itself is derived from ‘Luxury’ and ‘Sine’, symbolising the elegance of a ‘luxurious sine wave’ and a deep reverence for the artistry of sound. This commitment to sonic perfection drives the company, which views its products as a testament to seamlessly merging the purity of high-fidelity audio with a certain level of refinement. Luxsin operates on the belief that sound is a profound art form—not merely frequencies and waveforms—and in this review, we’ll see if the X9 delivers on the promise of an extraordinary listening experience. The Luxsin X9 is priced at $1099 USD.

Luxsin X9
Features
Let’s dive into some of the Luxsin X9 features. At the heart of the device is an AKM AK4191EQ + AK4499EX dual DAC chip solution, feeding a fully balanced amplifier section. The device supports up to PCM 32-bit/768kHz, native DSD512 and Hi-Res Bluetooth, courtesy of a Qualcomm QCC5125 solution.
The X9’s headphone amplifier delivers up to 4000 mW @ 32Ohm, making it powerful enough for any headphones you care to pair with it. And one of my favourite features is an intelligent impedance detection system that analyses your connected headphones or earphones and sets the ideal gain level to match (this can be disabled in the options if you want full control). This makes it easy to dial in the optimum performance without any guesswork, and so far, it has handled everything from hard-to-drive headphones to sensitive IEMs flawlessly.
The X9’s R2R volume control offers accuracy down to 0.1dB, allowing for tiny, precise adjustments without the frustration of over- or under-shooting. This level of detail makes listening effortless, whether I’m fine-tuning for critical tracks or simply enjoying music at a comfortable level.
One of the highlights of the X9 is its hardware-level HP-EQ: it applies real-time EQ based on each headphone’s measured frequency response. The current database has over 2,500 headphone models. You can pick your headphone model so the unit loads the corresponding EQ curve. It generally attempts to approximate the Harman headphone curve, but in many cases (like my Sennheiser HD650), there are multiple sound profiles available. You can bypass the EQ completely — HP-EQ can be turned off, if you prefer the default or “raw” tuning.
Furthermore, the X9 offers parametric EQ, sound style presets (such as rock and pop), crossfeed, soundstage width/depth controls, and subwoofer/bass management. To put it succinctly, the Luxsin X9’s sound can be tweaked in multiple ways, making it an extremely versatile audio source.
Design
The Luxsin X9 is a hefty piece of kit. Its chassis is pretty standard fare, with its anodised aluminium construction, but it’s built to last. Where it deviates from being a straight, boring box is its subtly faceted front corners and the distinctive 15° angled front face. However, this angle isn’t just for aesthetics—it’s a piece of smart design that provides a much better view of the 4-inch colour display and, crucially, makes the touchscreen intuitive and easy to use. The side panels feature subtle ribbing for heat dissipation, a smart consideration given the power under the hood.
The front panel is minimalist but comprehensive. The UI is nice and responsive, allowing you to swipe left/right and up/down to cycle through the settings and select from the multiple VU displays. There are currently nine in total, including some vintage styles. To the left of the display are three headphone outputs: a 4.4mm balanced, a 6.35mm single-ended, and a 4-pin balanced XLR output, nicely covering all your compatibility needs. On the right side is the tactile volume knob and a mute/standby button.
Around the back, the X9 is a hub of connectivity. For digital inputs, you’re covered with USB-C, standard USB, coaxial, and optical ports. There’s even an HDMI port that supports ARC, making it a great option for a home theatre setup. High-res wireless is handled via Bluetooth with LDAC and aptX support. You even get an analog RCA line-in if you want to connect another source. For outputs, you have your balanced XLR outputs and single-ended RCA outs, alongside a dedicated subwoofer out. It even includes 12V trigger in/out ports for system integration. The X9 truly excels as an all-in-one desktop command centre.
Sound
Sound
With all the features and technical wizardry the Luxsin X9 brings to the table, the natural question is: “Does it actually sound good?” I can tell you straight up, based on my excitement, that it sounds very, very good. Considering it’s an all-in-one DAC, headphone amplifier, and preamp around the $1,000 mark, you’d certainly hope so.
The biggest challenge in describing the X9’s sound is the sheer volume of customisation. The sound profile options are huge, and the truth is, this unit can sound like almost anything you want it to.
Bypass Mode (The Core Sound)
In my preferred listening mode—with the bypass filter enabled—the X9 presents as decidedly neutral and transparent. This is its “honest” sound. It’s uncoloured, true to the source, and reveals the genuine character of whatever speakers or headphones you are listening to.
I did notice it sounds a little softer and less dynamic than something like the D&A Alpha Pro, feeling a bit more airy and uncoloured in its default state. While it might not be the most upfront or bold presentation, it offers high fidelity without being aggressive.
Technical Performance
The technical prowess of the X9 is where it truly shines. It has a very spacious and wide sound stage, easily giving you one of the best you’ll hear for a device in this price bracket. Complementing this wide presentation is fantastic imaging, which helps you accurately place instruments and elements within the sound field. It even features a digital crossfeed option so you can further sculpt that sound stage depth and width if you fancy a more natural, speaker-like presentation.
Detail retrieval is also fantastic; the X9 is great at picking up both micro and macro details and really conveying the nuances in your music. Adding to this high technical capability is the fact that even with my most sensitive in-ear monitors (IEMs), the background noise is inaudible—you get that wonderfully black, silent background.
Bass and Power
The bass quality is, simply put, fantastic. It’s characterised by excellent control and very good extension, meaning you get the lowest of the lows. There’s no exaggeration here; it stays nice and tight, with zero bleeding into the mid-range or muddying up the overall sound.
When it comes to raw grunt, the X9 delivers. With up to 4,000mW in balanced output, it has great dynamics and laughs off hard-to-drive gear like the Sennheiser HD 650s—it’s not even breaking a sweat. The intelligent impedance detection system also makes it ridiculously easy to dial in optimum performance without any guesswork.
Verdict
So, is the Luxsin X9 the box that changes your desktop music life? After spending well over a month with it, I can wholeheartedly say yes.
If you’re like me and appreciate having just one piece of equipment on your desk that can accommodate all your different headphones, IEMs, and speakers—including a subwoofer out, which is a massive plus—this unit is an absolute winner. The sheer fun of those gorgeous VU meters is just the cherry on top, but the core performance is what counts. Whether you prefer the honest, transparent bypass sound or the truly endless possibilities of the HP EQ to perfectly sculpt your sound, the X9 delivers. It is a versatile, powerful, and highly recommended all-in-one unit. I highly recommend this one.
