This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:
Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.
Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.
Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).
45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.
If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*
* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty. Terms and Conditions

Powered by the lush sound of valves, the Fosi Audio Box X4 combines a phono pre-amp and headphone amp for complete system satisfaction.

Phono pre-amp and headphone amp combined
Combining a phono pre-amp with a valve headphone amp, the Fosi Audio Box X4 is perfect for a wide range of users. The phono pre-amp lets you convert the signal from an MM cartridge-equipped turntable to a line level signal. From here, it’s easy to output the signal to headphones, or a regular hi-fi system or active speakers, via the phono outputs.

The sound of valves
Utilising twin 5654W valves in the pre-amp section, the Box X4 has the warm and fluid sound that only valves can replicate. For a subtle change in sonic signature, you can replace the valves with other models (6AK5, 6AK5W, 6Zh1P and 6J1) at additional cost. Warmly glowing at the top of the unit, they add a visual warmth to the aesthetics, too.

Low noise phono pre-amp
Featuring low noise integrated circuits and high quality components, the Box X4’s phono pre-amp delivers audio that’s high in detail and low in distortion.

Input another source
As well as the turntable input, the Box X4 also features a 3.5mm AUX input. Perfect for a CD player, computer or other source, this further extends the Fosi Audio’s versatility, making it the ideal system hub.

Output to headphones or hi-fi
The facia-mounted 3.5mm headphone socket is directly connected to the valve pre-amp, giving ample power to most headphone models. Alternatively, simply connect to your existing hi-fi system or active speakers, via the RCA phono outputs. For sound that’s tuned to your taste, there are bass and treble controls.

Bridge the gap between your turntable and headphones, with the sweet sounding Fosi Audio Box X4.
