Review: Great little amp for the money. - Ordered the Fosi V3 to replace a Fosi 20a I had purchased some time ago. The main differences are, the V3 is a more simplistic setup, promises more power per channel, and uses high quality parts internally. It can come with either a 32 volt or 48 volt power supply. Opt for the 48 volt power supply, you will not regret it. The larger more powerful power supply will get you higher volumes with better quality output On the back side of this unit are connects for a pair of speakers and an analogue input. The older Fosi 20a just did not have as much power particularly with only the supplied 24 volt power supply and fell short driving my Polk Atrium 6 speakers at loud volume. Now, I am using this as a garage system. Hence, the reason I chose to go on the cheap with this system. But....the Fosi V3 got decent audio reviews so what the heck. The garage system is a music system to accompany working on projects or the cars vs. just sitting and listening to music like I do with my home systems that cost much much more. So after connecting up an older generation Echo device to stream music, I used 14 gauge audio cable to connect the speakers to the amp. Very easy to do. The result is as you see it in the attached video. Loud enough for me and the overall sound quality is very good. So, this unit has few connectivity options but what it does, it does well. What I really like about this amp is its small size allowing me to store it in my garage wall cabinet. I would imagine this amp could be part of a home system in a small to mid size room Just be sure to match it up with a pair of good speakers. Speakers with a high efficiency rating will serve you best that is 90db or better. Recommended.
Review: Excellent Beast of an Amplifier - Don't believe the 300 watt claims of the manufacturer. (I don't know why they just don't rate the amp with RMS real world specs). Still the Fosi Audio V3 is an excellent amplifier when paired with the optional 48V power supply, although it increases the cost. With the supplied stock power supply, the amp can deliver about 30 watts of real power and with the 48V power supply it can deliver about 80 watts of unadulterated bliss. The sound is clean with absolutely no hiss. You can tailor the sound by easily replacing the socketed OpAmps inside the amp, just make sure you insert them with the proper polarity. OpAmps can range from several to over a hundred dollars for a set. Better OpAMps can give you better depth and a wider sound stage as well as a mellower sound. Remember this is a no frills amplifier with only pair of inputs, it is basically a volume knob and nothing else. But this is perfect when used as a desktop amplifier to drive a pair of desktop speakers. In this mode of operation, you do not need the optional power supply since most desktop speakers are quite efficient and do not need much power. The 48V provides a more heft to the sound with the added power. It can easily deliver enough power to drive most speakers. With either power supply, the amp seems capable of driving even 4-ohm loads without distortion which most modern amps fail to do. Some Pros: * Cheap but great value * Compact size * Very efficient * Swappable OpAmps * High quality components: Elna capacitors, WIMA Output capacitors, Sumida inductors and NCC Capacitors Some cons: * Fosi used to supply the amp with the copper volume knob as well as the black one but it is now an added option. * The amp goes to sleep rather quickly after the input signal is cut. It takes about six seconds for it to come alive when signal is restored. * There is only one pair of RCA inputs * No Bluetooth capability * No subwoofer output

## Questions & Answers

**Q: Even if you put a 48v 11a power supply on it you would still be short of 600w, does this make any sense? is it really max 300w but miss advertised?**
A: That number is misleading, it will never gets to 50watts

**Q: Are each channel mono block? So I can send a differential signal to the rca inputs. Thanks!**
A: https://www.amazon.com/SPRODIO-Converter-Adapter-summing-SC21/dp/B0BRZCGY29/ref=sr_1_1?keywords=stereo+to+mono+converter&qid=1684854327&sr=8-1

**Q: Total new to this. i have a pair of sony sscs5 bookshelf speakers. i don't see a way to add a subwoofer. am i correct?**
A: You either need a 3 channel output device (most basic devices without a sub out are just 2 channels) that can run straight to the sub, or a subwoofer that can accept RCA, and split the RCA signal that would feed this amp before it goes to the amp with two RCA splitters or a stereo RCA splitter cable.

**Q: Does the V3 come with a power supply? If so, which one?**
A: It comes with a 5A, 32VDC power supply. It can put out 160 Watts of power (5A x 32V), not 32 Watts as another answer incorrectly states.

### ⭐⭐⭐⭐⭐ Fosi Audio V3: A Budget Amplifier paired with really nice speakers?
*by D***R on July 26, 2023*

I had been hearing about the release of this amp from various forums and decided to experiment with it with a couple of speakers that I have acquired I’ve the last 6 years I or so. I’m a bargain hunter at heart. On one end, I have a pair of Klipsch LaScala’s from the early 1980’s that I resurrected from the dead. They were in horrible shape and came from a church that used them as their auditorium PA. They are know for their efficiency and usually have synergies with tube amps. On the other end, I have the electrostatic Martin Logan ESL’s, which sound completely different, are very detailed and have a reputation of being challenging to drive, although the newer Martin Logan’s don’t have this problem as much. I have been using a 90 watt per channel tube integrated amp and was really looking for an amp that was much cleaner and imparted less distortion, which a tube amp for the most part is built to do. The tube amp sounds great but it seems to blur the sound a bit, if that makes sense. With the LaScala’s, the V3 power was way more needed to drive them. It didn’t sound harsh or brittle and in fact, was completely quiet with the volume knob maxed. My tube amp imparts a slight hiss at the tweeter that is audible from my sitting position. The V3, checked all the boxes and did everything well. The highs and mids were nice and balanced and the biggest difference was with the low end. I have 2 SVS SB1000 subs and the V3 really provided nice and controlled texture to the bass region, something that was lacking in my tube amp. I won’t go as far as using the magical language to describe the sound that many audiophiles use but as this is a subjective review, what I can say is that the amp did its job and at this price, it really is a no-brainer for people that even are wanting to use this will quality speakers. Martin Logan ESL’s Challenge: These speakers are known to have dynamic impedance swings, with ohms that often dip, making them a tough act for many amplifiers. But the Fosi V3 didn’t strain at all. It provided consistent power, ensuring the ESL’s remained articulate and expressive. Much better than my tube integrated. The dips in ohms which could cause some amplifiers to falter, only showcased the stability of the V3. Very surprising for the low cost. Again, what can I say…these small inexpensive amps have improved to the point where they are an incredible value. Conclusion: The Fosi Audio V3 isn’t just a budget amplifier. It’s an amplifier that can be used with expensive speakers. For anyone hesitant to use the Fosi in similar use cases, give it a try. For the price, there’s very little to lose.
