## Description

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

Review: Very low electricity/power usage - There will be all sorts of great and well deserved reviews of this amp but one thing I wanted to show was the actual electrical power usage of this fantastic little amp. See attached picture. This FOSi Audio v3 amp is using only 3W when driving a pair of Wharfedale 9.1 speakers @6 ohms. Fed by a WiiM Pro streamer with it's output audio set at 95% That's absolutely incredible in this day and age of high electricity prices, incredible. Previously was using a Harman Kardon AVR130 and it's power usage was nearly 70W on idle, not even playing anything. Amazing clean sound from the amp and it drives the 6 ohm wharfedale speakers effortlessly. So happy with this lovely little amp, amazing price too. Would've liked if it came with a remote, otherwise it's perfect!
Review: Remarkable little amp - Bought this for my study, with a 32V power supply, to drive a couple of small, 6 Ohm, Quad desktop speakers. The foot print is perfect for a desktop (it has replaced a full size integrated amp and leaves me a lot more space). Seems very well put together, suitably weighty, nice heavy case. I like the logarithmic volume pot, it works very well in this application, although I see that some other people don't. The power LED is bright enough to see, but not distracting. I find it is very nice to listen to, good detail, pleasantly lively. I'm quite fussy about audio gear and wasn't sure whether I'd like this, but I am impressed. Sound quality is remarkable, given the small size and the very reasonable price. I might even treat myself to an orange volume knob for it.

## 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.

### ⭐⭐⭐⭐ Fine for small rooms but doesn't live up to the hype
*by D***6 on 19 February 2024*

I'd seen stellar reviews of this amp on YouTube and got it when it appeared on a deal of the day. I tried it in place of a Denon RCD-M37DAB mini system in my kitchen, with Wharfdale Diamond 9.1 speakers. After switching between the two several times I couldn't make out any significant difference between them. In its day (2008) the Denon was winning awards and high praise, so this tiny Fosi amp matching that performance for silly money is an achievement in itself. However, in no way is it the 'giant killer' that some reviewers claim. For a start, the 300W power rating is a joke. Digging into the Fosi website shows that to be with a 48V 10A power supply, that Fosi apparently doesn't even make, let alone supply! It's also at the clipping point of the amp and so would have awful distortion. With the 32V standard supply in the box, I've seen reported test results of 30W into 8 ohms and I think that's probably about right, given the volume I was able to get in my fairly small kitchen, with the volume knob turned up over half way producing 75-80dB. So in conclusion this is a nice little amp that is perfectly suitable for small rooms, at least with the 32V supply. At the price it's brilliant value for money, as long as you don't buy into the hype and expect too much from it.
