Fosi Audio DA2120C 240W Bluetooth 5.0 Stereo Audio Hi-Fi DAC Amplifier Support aptX 24Bit-192kHz 2.1 Channel Integrated Class D Power Amp with RCA/PC-USB/Coaxial/Optical Input and Remote Control

The media could not be loaded. I am a big fan of Fosi amplifiers. They have a very small footprint, they are very easy to use, they address a variety of audio needs, all their models are well priced, they are extremely easy to hook up, and they have the power to generate great sound on both bookshelf and floor speakers. I use them in my home in different rooms, in my office, and outside by the pool. I use them to carry sound from my family room amp to sync into different rooms, to expand the sound of my TV, to control and play music in remote areas like the pool. With the small compact size and reliability they have also made a great addition for music and expanded TV sound in airb2b rental properties. As a testimonial to my satisfaction with Fosi -- this is the seventh Fosi amplifier I have purchased in the last three years.I purchased this Fosi DA-2120c to use in my office. The DA-2120c provides a variety of inputs including Bluetooth, Aux, Coax, USB and Optical. Connecting the amplifier in my office I am able to stream sound from the TV using optical interface, expand the sound from my PC using a USB connection, or I can simply play music from my phone via Bluetooth for background sound.Quality of the DA-2120c Unit:The amplifier is made out of aluminum, small, light weight and sturdy. The display on the front is OLED and very easy to see / read the source and volume level. The 2.1 stereo system easily powers passive speakers on a left and right channel, as well as a sub-woofer. While I typically use them for bookshelf size speakers, I have also used them to power larger floor speakers without issue.Package includes the DA-2020c unit, low voltage power cord, a 2-ft optical cable and the remote control.Installation:Hooking up the DA-2020c Fosi unit is extremely simple. It is truly plug and play. Connect the speaker wire to the right and left channel screw connectors, plug in the sub-woofer cable into the pin slot, plug in the electric cord and plug in any input cables you would like to use. Or as I do in my airb2b rentals -- you can simply set up the interface to use Bluetooth and power the audio speakers. The unit is so small and compact you can put them anywhere. In my airb2bs I put the amp on top of the kitchen cabinets so the amplifier is concealed, but still easy to access and use from your phone.How I use my Fosi Amp(s):I use my Fosi amps for a myriad of applications. I most often connect from my phone and use a music app like Spotify, Amazon music, Pandora, etc; but I can also Bluetooth directly from my Amazon Echo to expand the sound and use all the functions of Alexa; I use the optical cable interface to expand the sound of my TV or to have music carried from the larger amp in our family room to sync music throughout the house. I have also found a great application with TV installations where I use the Aux or optical interface and I control volume and stations with my television remote; or I use the USB connection interface to expand the sound of my PC.For Bluetooth pairing to the Fosi amp is very easy. While you cannot name the Fosi Bluetooth source, every model of Fosi Amp has a different name when you go to sync.While you can control volume and input sources from the Fosi device itself, I usually manage everything from the source – my phone, the TV, Alexa, or a larger amp in another room. When I need to I can use the handy remote control for the Fosi unit, but for most of what I need is volume control and doing it from the audio source gives me everything you need for control – When I need to change the input I use the Fosi handy remote control.I have implemented the DA-2120c in my office to stream audio from my computer, enhance the sound from my office television, and to simply play music from my phone in the background.The only feature I wish the Fosi amps included was the ability to Bluetooth connect to multiple Fosi amps at the same time.To summarize – the Fosi amp is dependable, reliable, super easy to hook up, easy to use, and has a wide range of applications. Love the product……...

Fosi makes some great sounding amplifiers. This was my second purchase of a Fosi amplifier because the first one I purchased 3 years ago was phenomenal so I bought this one which has more than double the output power and delivers the same clean output that the smaller one I bought does. The quality control is just as good in the new unit 3 years later which is amazing. The amp runs cool but delivers and honest 75 watts per channel up to full volume with little to no distortion using the SPDIF input driven by a grace digital internet tuner. I am driving a set of Neumi BS5’s and can crank this thing up and it blows me out of my bathroom every night. Yes I have this system inside of a bathroom linen cabinet it’s that small. Runs cool and is rock solid. Bluetooth connectivity is also a breeze and sounds very clean. The unit has a decoder volume control which is very fine so when you raise the volume you gotta crank it a few turns to go max. This amp can go to volume 99 and still does not clip as long as you have a set of speakers that won’t go up in a puff of smoke. These amps are real nice for the buck. I use them in my shop as well. They hold up well even with my torture tests.

I had the little brother of this amp (the DA2120A) and really loved it! But, I'm running the Micca RB42's and they are quite inefficient. Really, even that combo is more than enough for desktop use. You will not be disappointed with that combo! I was wanting a bit more power, so I upgraded to the Fosi 120W amp!This amp is the big brother to the DA2120A with a slightly larger package and much more power. It's a fantastic piece of equipment at easily double the cost. I haven't tried the bluetooth input as I'm running USB from my PC. If you have more efficient speakers, the little brother of this at 50 wpc is plenty. If you have anything under 87db, I would recommend this guy.I own some very high end audio equipment (system approx $10,000) and consider myself at least an amateur audiophile. Currently, I'm full timing in an RV so space is at a premium. This Fosi DAC/Amp with the Micca RB42's and a low profile Dayton 10" powered sub make for a super compact but incredible sounding 2.1 system for music or movies. I'm running mostly 320k Mp3 music at 24bit 192KHz and it sounds really, really nice. I can't really speak to imaging or other more subjective qualities of the amp as I'm in a sub-optimal space to evaluate that. Distortion is low, it looks beautiful on the desk and it's totally packed with options. I love this amp! Even the remote is great. It's just plastic but it does exactly what I need it to.I returned the first DA2020C as defective because I had no sound output at 192KHz from my PC USB. The second one was the same. I run both Window 10 and Linux and both had the issue. I finally played with my settings enough and it started working. I'm wondering if having the little brother of this amp running at first caused some kind of driver confusion when this was plugged in. I'm not sure. But, I am sure that the seller was very helpful, offering clear and useful advice on possible ways to resolve the problem. The excellent support makes this amp even more of an easy choice!
