Unrivaled sound quality meets affordability in the Fosi Audio Box X4 Phono Preamp. This comprehensive review details my extensive experience with this fantastic little device.
For years, I struggled with the muted sound from my turntable. My old system lacked the vibrancy and clarity I craved. The music felt distant, lacking the detail and richness I knew was present on my beloved vinyl records. A proper phono preamp would have significantly improved the listening experience, transforming my vinyl collection into a truly immersive auditory adventure. The lack of a quality preamp meant a subpar listening experience and frustration every time I listened to my vinyl records.

Essential Considerations Before Purchasing a Phono Preamp
A phono preamp is an essential component for anyone wanting to enjoy the warm, rich sound of vinyl records. It bridges the gap between your turntable’s low-level output signal and your amplifier or receiver’s higher-level input. Before purchasing, you need to consider several factors. The ideal customer is an audio enthusiast on a budget or someone who owns a turntable with a moving magnet (MM) cartridge. This is NOT for users with moving coil (MC) cartridges, and for those users a different preamplifier will be necessary. The most important things to consider are the preamp’s compatibility with your turntable’s cartridge type (MM or MC), its noise floor (lower is better), and its gain control range. Finally, read reviews meticulously; user experience is invaluable in making an informed choice.

The most striking aspect of the Fosi Audio Box X4 is its surprisingly rich and detailed audio reproduction. The vacuum tubes contribute a warm, analog sound that is incredibly pleasant to listen to, adding a depth and richness often absent from more digital-sounding preamps.

I’ve used it with my turntable, my smartphone, and even my laptop. This flexibility is rare at such an affordable price point. The ability to connect a variety of devices—from my turntable to my phone, to my laptop, and even to powered speakers—transformed how I listen to music. The integration was incredibly simple. The connection process was intuitive and straightforward, requiring minimal technical expertise. The versatility ensures ease of use for listeners of all skill levels, regardless of the variety of devices they want to use.
Bass, Treble, and Volume Control
The built-in bass and treble controls allow for fine-tuning the sound to match my preference and the characteristics of my speakers. This level of control is not always found in similarly priced preamps. I’ve found this especially helpful in compensating for the acoustic properties of my listening room. I can effortlessly fine-tune the sound to my liking, which improves the overall listening experience.

Tube Replacement Options
The ability to swap out the tubes is a fantastic bonus for those looking to experiment with different sound profiles. Though the included 5725W tubes sound wonderful, there’s room for personalization according to the user’s preferences.
