## Description

Enjoy rich, detailed audio with this compact, durable power amplifier featuring advanced heat dissipation and customizable op-amp design for personalized sound.

Review: Excellent Amplifer! Very musical results far beyond its price - An amazing amplifier given its size and price point. Properly set up, run in for 24 hours and with a decent Hi-Res Audio signal input, decent cables and suitable speakers and it makes music. The sound is very clean and detailed with no harshness or sibilance. The flat signal response reveals a lot of detail in the music. Not weighted to either end of the frequency range. Very dynamic, good fast attack on solo piano - always a difficult one to project realistically. Not a sound that is aggressive or wearing to listen to. Choosing matching components to provide a balanced system is important, so give it an MP3 input signal you get what you get - medium results, not Hi-Fi. As always one is listening to the system, not individual components. System matching very much matters to the tonal colour especially with cables and speakers. Certainly changing the speakers to +£1000 Spendor, Monitor Audio, Mission etc would unbalance the system and reveal some short-comings - but that would be to use this amplifier far outside its scope of system. One comment I see on several other reviews is the volume control level position ... In my opinion, this knob should be pulled off and set to the 6 o'clock position with the amplifier off (a bit like some older Naim units). Them when the unit is turned on, the volume control rate and progression are correct, in comparison with most expectations with minimum volume around 7 and 10 - 11 being a fair listening level. The 48v PSU now supplied with the unit is capable of providing the dynamic transient peaks without strain, providing adequate reserves and control to avoid 'smearing' of fast pieces and allow quiet passages to feel realistically contrasted with a wide dynamic range. The simplicity of single input and dispensing with tone controls means fewer sound compromises, and gives a superb perfomance far above the expected quality at this price. Enabling you to stop spending more cash on Hi-Fi and spend more on the music itself. Very enjoyable music-making and Very Recommended!
Review: Perfect amp - Great Class D amp, very powerful (more than enough for most high end speakers) and very low energy consumption comparing to much bigger Class A/B amps. A truly fantastic product for the price so excellent value. Solid build quality, compact and does not overheat.

## Questions & Answers

**Q: How to change audio balance levels between the left and right audio channels?**
A: 1. Computer: Settings > Sound > Fosi Audio, and change the left and right balance levels. 2. iPhone: Settings > Accessibility >Audio/Visual> Balance, slide horizontal slider to the left or right to adjust the balance.

**Q: Do I need a pair of the same opamps or can they be swapped in different combinations?**
A: If your OP-AMP is pin-to-pin (P2P), meaning the pins and functions of the two OP-AMPs are exactly the same, so you can directly install one model at a time. However, there might be a difference in sound quality or sound volume on one side.

**Q: What is a difference between two versions of V3 amp - 32v and 48v?**
A: Compared to a 32V power supply, a 48V power supply can enhance the amplifier's power output, providing more headroom to prevent distortion and enabling it to drive larger, more powerful, or higher-impedance speakers.

**Q: Can the V3 amplifier be bridged to work as a monoblock amplifier?**
A: It doesn't support bridge mode.

**Q: Only one channel has a sound or unbalanced output?**
A: Cross-check left & right speakers, speaker wires, input cable eliminating either speaker or wiring. Please ensure that the speaker wire is correctly connected and not bent.

### ⭐⭐⭐⭐⭐ Perfect amp
*by D***N on 3 February 2026*

Great Class D amp, very powerful (more than enough for most high end speakers) and very low energy consumption comparing to much bigger Class A/B amps. A truly fantastic product for the price so excellent value. Solid build quality, compact and does not overheat.

### ⭐⭐⭐⭐ Amazing sound but lacks an important feature
*by R***S on 31 December 2023*

I can't compare this amp with any other products in the same class D amp category, there might be a better performing amp for this price. I first tried it with my big Tannoy Cheviots but this was obviously asking too much for the little V3 to bare. However when I hooked it up to my Tannoy Revoutions, the full potential was immediate. As a nearfield amp, it works perfectly well. The makers have not correctly labeled the pre-out socket. This is in fact, a fixed line level out. This is only useful for connecting to a recording device or maybe to another amp that has its own volume control. So if you want to use this unit to power a subwoofer, you will always be adjusting the volumes to match each other. Just as a stand alone amp, paired with the right speakers I doubt if anything beats the price
