Fosi AudioDA2120C Bluetooth Amplifier 120Wx2 Stereo Hi-Fi 2.1 Channel Wireless Stream aptX, 24Bit/192kHz Class D Power Amp USB DAC Coaxial Optical Decoder, Support Subwoofer & Remote

So I wouldn't normally write a review, but I was nervous buying this so thought it would help others.Bought this to power some big, old-but-good floorstanders and run audio through off a high-end sony smart TV. Was deciding between this and a £1k stereo hifi amp with DAC. The smaller mini-amps are too low power for my needs so went for this. Really good decision and saved me a packet. Plus the box is tiny.I've connected it to TV through the digital optical port so can watch TV plus run audio from phone through smart TV over wifi for easy music playback. The sound quality is great, very crisp, I can't hear any buzz at all. Volume is not crazy high on my system, but more than enough for 'normal' living room use.I tried the bluetooth but this doesn't sound quite as good, although still nice. That's more a bluetooth tech constraint though than anything to do with this device as the DAC is clearly very capable.Downsides are it won't sound as good with bluetooth and no inbuilt wifi streaming. Remote is pretty budget looking. Also if you insisted on HDMI eARC for absolute best audio transmission this doesn't have it.

Came quickly easy to plug great sound I have it connected to my optical out from TV coupled with Monitor Audio bronze bookshelf speakers sound very clear. Bluetooth with mobile phone is easy to connect. A few audio connections you can tweak I used Hifi and seemed to work well. Volume wise I use it at 60 plenty loud enough goes up to 100 would say its not up to audiophile standards of an expensive amp but its good enough and the remote is very intuitive. Good customer support offered although I didn't need it. I would recommend it for this price

I am happy to quality of sound and EQ modes. Nice build and design. But disappointed of real output power. From my new TV's BT signal output sound is very low, (set max from TV and max from ampl).From optical signal is better but I have to set volume 50 - 70 to even hear enything. Definatelly is not 100 watt output. I was tested cheap £20 amlifier with the same speakers and volume was much more higher.Seller gave me a tip, long press 'DISPLAY, button you set 'HI-GAIN / L-GAIN'. It's help a little a bit. But why this option isn't on the user's manual?

Amp works great, simple set up with great sound output. Nearly a year later when my power brick to the amplifier blew and Fosi sent me a new one straight away. 10/10

I originally bought the Creative Labs DAC for hundreds and it was not only poor sound quality but it broke after three weeks so Amazon took it back. I must’ve sat there for days looking at the £500 Denon alternative and umming and erring about whether it was worth it.I have hooked this up with B&W 600 series speakers and a Q Acoustics 3060s Active Subwoofer connected to a high-end gaming rig. The sound output is crisp at the top end and the bass precise and punchy with the mids clear and pronounced. If you also have a Secret Labs Magnus desk this fits perfectly in the hideaway tray with just the antenna visible for connectivity to other devices.I have tried a few solutions, this ticks all the boxes, I would be happy to have this in one of my main rooms as a primary audio source if it was needed. You won't regret your purchase with this bit of kit.

All in all great value. I was running separate DAC - Topping D30, & Amp - SMSL SA 98E which was a brilliant combination but there were too many switching steps for other members of the household.This is a very neat package DAC and Amp in one small package - about the size of a largish hardback novel. Tried the Fosi Audio DA2120A which was neat but not enough power for my 8ohm floor standers - had to drive it hard and things started to distort after 70.The DA2120C unit drives the floor standers very well. DAC & AMP in one box, a remote for switching (auto switch on source would be an excellent next step for development) - family very happy and I can live with it.Negatives : Tiny display - if you wear specs (I do) you'll need them.Good work Fosi.

If you're thinking to yourself 'This has all the features I want maybe it's worth it even though it's quite pricey', let me stop you right there. This thing is not even remotely worth what it costs.I am seriously regretting this purchase, neither the optical or bluetooth inputs work. Like at all, I have the hilariously huge antenna attached an my phone cannot see it to pair with it, nor can any other bluetooth device I have. I just wasted an hour of my life trying to get the optical input to work, it simply does not function. I bought this more expensive amp because I wanted to use these two features, total waste of money. On top of that, the EQ controls are just a small handful of crappy presets like 'Jazz', 'Rap' and 'HeavyRock' none of which sound even remotely decent. The two 'loudness' modes also sound horrifying with huge low-mid boosts that sound totally disgusting. Basically all the tone shaping controls on this amp are trash. Like other reviewers here I also seriously doubt this thing can deliver 120w per channel, I'm using 50w speakers and it's only just capable of driving them.I have never been more disappointed in an amplifier than I am today and I've been through a lot of audio equipment over the years. The product page for this thing is straight up misinformation but I guess Amazon really doesn't care that much about false advertising.

I could not get the digital connection to work (from an older TV). The amplifier runs hot (much hotter that I would expect from modern audio equipment). The bluetooth quality is reasonable and the TV RCA connections are OK.
