A Giant Killer! Fosi Audio V3 Mini Stereo Amplifier Introduction

Nice! 👍🏻

This could be a baby topping la90d. Maybe in a next iteration you could have some of those switches in the back (so it bypasses volume control and can work as a monoblock) The ventilation is a good idea but maybe not on top, because that way it collects dust inside very easily. Bottom and sides is best. Apart from this it seems like a very nice piece of gear. Good job!

Butt duz it support buttplugs?

I am sold! Just ordered mine ;) I anticipate these are going to fly

Would you please also sell a quiet 48VDC 10A SMPS suitable for use with the Fosi Audio V3 amplifier?

I have to wonder why, in a whole bunch of good decisions about cooling and power supplies, they would make the totally dumb move of putting the power switch on the volume control. That renders the amp useless in a fixed gain scenario where it is being fed by a device with it's own volume controls. Shutting it off and turning it back on now requires adjusting the gain, every single time.

Nice improvements ... but with one deal breaker flaw.

Hi, will this be available in Indonesia?

thank you so much for your work. Please tell us when an amplifier similar to V3 with a built-in DAC and optical input will appear in your product line?

Great video, i would like to ask how is the Dynaudio Emit20 sounds with this amp ? Are they a good pair? Thanks

Any recommendations for a preamp with tone controls to produce warmer softer sound? Preferably something with a compatible design, and comparable price to performance value?

What is the warranty when buying in the US? And is return shipping free?

What's the name of the big op amp?

😮😮😎

Fosi needs to get into car audio,head units

Was the V3 output measured only at 1khz, 10% THD or 20hz-20khz, both channels driven 1% THD? And why can't the company have an actual person make a video?

I have some DAC's and some class-D amps, including a Fosi V3. I would like to have an inexpensive device that allows me to do digital room calibration, for example a digital in/digital out DSP

The screws on the bottom are so tight it is impossible to remove with a normal hex wrench. Any tips how to get them loose?

…maybe an XLR or 6.35 Jack balanced version with an orange light instead of blue…

what a kind tube preamp from Fosi have opAmp can be switch it (DIY)?

600 watts lol, of course it does.

just wish you guys would make a pre amp tone control (With out tubes) simple bass and treble like found on the tb10d

Is there a chance to have a volume remote control on a future V4 version ?

What makes the V3 better than the BT20A Pro?

Hey. Can I use the power supply of 4.8V 10A DC?

every time i think i need to upgrade from my sparkos equipped v3s i turn my system on and here....no noise and great sound. i do have the 48 v power supply and I'll keep them until they stop working. great little class d amp.

Tu ressembles trop à un dessin animé,man, fais gaffe !!

I just bought one to fill in for an older NAD 216thx. Plus, I wanted a good sounding, low priced amp for back up. I own the Fosi MO4 for a sub I built and am happy with its performance, so I decided on the V3 after some comparisons. Upstream I am feeding it with a WIIM pro streamer, RME ADI-2 DAC fs and a Schiit Freya N preamp. The V3 is powering a set of Cerwin-Vega! vs100 3-ways. They have a 10" woofer, 6 ohms and have 95db sensitivity. Sounds awesome, suprising bass and crystal clear even when I crank it up. Excellent amp for smaller room set ups. Great price.
Edit: I use the 48v 5amp power supply.

I recently used the Mission LX-1 MK2 series speakers, but unfortunately, the speaker coil was damaged due to connecting a low-wattage speaker. I understand that this was my mistake. I’m now looking to build a DIY speaker for this amplifier and am considering purchasing components from DIY Audio Cart. Could you recommend suitable midrange drivers and tweeters for this amplifier?

I bought one because the Fosi Audio website specifies that it is capable of 2 ohm speakers, so does this video, but doesn't list the output capabilities. After purchasing it I contacted tech support to get specs & was told it can't do 2 ohm...

My speakers are 2 ohms & that is why I bought it, so that is what it is getting.

Is it going to shutdown (to prevent damage}, or let the smoke out?
