Luxsin is new premium sub-brand from the Zidoo Group, positioned to focus on high end audio products.  Eversolo from the same Zidoo group has already made waves with its DMP-A6 and A8 streamers, which quickly set a new standard in their price range. Building on that success, They decided to create a new brand: Luxsin. With a new mission to step deeper into the high-end audio market with products that place sound quality above all else.

The brand’s debut model, the Luxsin X9, embodies that mindset. Not only is it a headphone amplifier, but a DAC and preamplifier in one chassis as well. 

With the X9, Luxsin demostrates its focus to compete with established names to bring fresh energy and focus to the audiophile scene. In this review we will take a closer look at their debut model, The Luxsin X9.

Design & Build Quality
The Luxsin X9 makes a strong impression with a solid construction and refined design. With a chassis that feels robust and well-machined, giving the unit a sense of durability that matches its premium positioning. The moment you unbox it, the X9 immediately conveys its solid weight and build quality.

The brushed aluminum finish not only adds a touch of elegance but also helps with heat dissipation during longer listening sessions. Buttons and knobs respond with precision, offering a reassuring tactile feel that reflects careful attention to detail.

The display is crisp and clear, making navigation straightforward without feeling cluttered. On the back the layout of inputs and outputs is nicely organized. Allowing for convenient integration into both headphone and stereo systems. Overall, the X9 leaves a decent impression.

Specs

Sound quality
From the first moment I started listening, the Luxsin X9 impressed me with a refined and slightly warm character. It delivers plenty of detail without ever sounding sharp or clinical. Instruments have a natural presence and there’s a smoothness to the overall presentation that makes long listening sessions very enjoyable.

The soundstage feels wide and well-layered, with good separation between instruments. Vocals sit a little further back compared to some DACs I’ve tried, giving the X9 a more relaxed and atmospheric quality. It’s not the most forward-sounding unit, but instead it creates a sense of depth and space that draws you into the music.

One feature I truly enjoyed is the flexibility the X9 offers. With its headphone EQ database, soundstage adjustment and crossfeed options, it’s easy to fine-tune the sound to personal taste or to better match the X9 with different headphones. Even without these tweaks, the stock sound is already excellent, but having these tools makes the X9 a very versatile device. The X9 sounds spacious and engaging, with a very controlled bass response. It sounds very musical and fun.

IEM Performance
With in-ear monitors, the X9 performs exceptionally well. Even with sensitive IEMs, the background remains completely silent, no hiss or unwanted noise. Combined with the extensive EQ database, the X9 offers outstanding compatibility and flexibility for IEM users.

Headphone performance
The X9 has enough power to drive demanding headphones even such as the HIFIMAN Susvara. In bypass mode, it can tonality feel somewhat flat. Activating the headphone EQ transforms the experience. You can tailor the sound to your own taste.

Treble
The treble on the X9 is smooth and refined, with just the right amount of sparkle. It never comes across as harsh or fatiguing. Everything sounds crisp and natural and there’s a nice sense of air in recordings. The highs never become too bright and stays comfortable, which makes the X9 easy to listen to for hours.

Midrange
The midrange feels clean and well-balanced. Vocals are natural and textured. The Luxsin X9 has a smooth laid-back sound signature. Nothing is pushed too much forward. Instruments like guitars and pianos sound lifelike and full, with more than enough warmth to keep everything engaging.

Bass
The bass performance of X9’s is excellent. It is very clean and controlled, with impressive texture and layering. It hits with authority when the music demands it. Not in an exaggerated way, but with a sense of layering and control that keeps everything tight and well-defined. Bass notes never smear or overpower the rest of the spectrum.

Soundstage & Imaging
The soundstage is wide and expansive, with clear separation between instruments. There’s a good sense of depth, making music feel layered and immersive.

Vocals and central elements tend to sit slightly further back, which enhances the feeling of space. Imaging is precise and instruments are placed accurately, The soundstage adjustment options give you the option to tailor the presentation to personal preference.

Listening Impressions
The following selection of tracks were chosen by me to explore a wide range of sonic attributes; from microdetail and imaging to rhythm and textures. The music illustrates what I’ve tried to convey above. 

Celebrating John Williams – Los Angeles Philharmonic – Olympic Fanfare and Theme
The Olympic Fanfare opened with a commanding brass section, delivered by the X9 with weight and clarity. Trumpets soared with a brilliant, golden tone, while the percussion drove the rhythm forward with crisp impact. The strings added breadth and grandeur, layering a shimmering backdrop that filled the soundstage. The X9 captured the sweeping dynamics with ease, balancing power and precision. The triumphant crescendos carried an energy that felt both majestic and uplifting, showcasing the Philharmonic’s full scale without losing subtle detail.

John Lee Hooker – The Healer
The Healer revealed its full character as a collaboration between John Lee Hooker and Carlos Santana. Hooker’s deep, earthy vocals were rendered with a striking presence. Santana’s guitar lines float effortlessly in the mix: smooth, fluid and full of tonal color. The X9 kept the bluesy groove grounded with a warm, rounded bass, yet gave the guitar and voice space to breathe. This created a natural tension between raw grit and silky expression. Hooker’s voice and Santana’s guitar were convincingly captured by the X9, making the track feel alive and immediate.

Harry Connick jr – Danson Du Vieux Carré
The moment the track started on the Luxman X9, it felt like I was standing right in the middle of a New Orleans street party. The brass jumped out with such vibrant energy, sharp enough to cut through but never harsh. Harry’s piano had this warm sparkle that kept the rhythm playful. The drums and marching beat pushed the whole tune forward with infectious drive and the bass rolled underneath like a steady heartbeat. What really struck me was how alive it all sounded, every instrument had its place, yet together it felt like one big, joyous parade moving right past me. The Luxsin X9 delivers.

Sinne Eeg – Remembering me – Up from the skies
Listening through the Luxman X9, this track immediately drew me in with its intimacy. Sinne’s voice floated right in front of me. The upright bass had a deep, woody resonance that felt rich and never overbearing. The drums added a gentle swing, precise but relaxed. The X9 gave the piano room to shimmer in the background, supporting the vocal line without crowding it. The warmth of her tone, the air around the instruments, were amazing.

Sophie Milman – Take Love Easy – Take Love Easy
This live rendition of Here We Go Again felt wonderfully alive. Willie Nelson’s worn, intimate voice carried a soft warmth, while Norah Jones answered with her smooth, velvety tone. The X9 captured every contrast between them with ease. The brass section, guided by Wynton Marsalis, had a playful bite that cut through the mix but never turned sharp. The rhythm section kept everything swinging, bass notes round and steady, drums crisp yet relaxed. You could almost picture the stage, with each performer stepping forward and then blending back into the ensemble.

Conclusion
The Luxsin X9 is a bold debut for a brand entering the high-end audio space. 

What stands out most is how complete the package is; a refined DAC, a powerful headphone amplifier and a flexible preamp all rolled into one. The interface feels modern and user friendly.

Add to this extensive customization options, EQ profiles, soundstage adjustments and crossfeed, you have a device that completely can adapt to your own personal taste. 

The output power is more then enough to handle anything from sensitive IEMs to demanding full-size headphones. Sonically, the X9 offers a slightly warm but highly detailed presentation, with smooth treble, natural mids and bass with weight and control. The soundstage is wide and layered, creating an immersive and engaging listening experience.

X9 strikes the right balance between musical enjoyment and technical capability. It doesn’t chase unnecessary features but focuses on what matters most: sound quality and versatility. At this price point, I generally think it is one of the most exciting all-in-one solutions currently available.

The Luxsin X9 is a versatile, musical and exciting debut. It is a refined all-in-one that I can convincingly recommend.
