Fosi Audio MC351 2.1 Channel Integrated Amplifier with DAC, Home Audio Stereo Power Amp with Dual TPA3255 Chips for HiFi Passive Speakers, Vintage VU Meter Receiver with Bluetooth and USB/Opt/Coax

I got this amp for a tiny little TV/media room and have been pleasantly surprised. The sound and practicality of it are great for the price.It's small and looks good, so much that I built this thing its own shelf to match the TV's and show it off. The VU meter is pretty much meaningless but adds a fun touch without being too "retro." My family also really appreciates its simplicity. There are only a few controls and no remote to lose.The sound: paired with some old JBL "control room" monitors (now hidden behind the TV screen), and using the optical input, movies sound immensely better, compared to the built in TV speakers. There's a really nice stereo separation that actually makes the screen seem bigger.I'm also using the RCA inputs (for a turntable with its own preamp) and the bluetooth connection (for my phone). Playing records, the sound is hit or miss, but it's hard to know the source of the inconsistency. Some recordings with a bit more space in the arrangements sound fantastic, while more "wall of sound" type things don't sound as good -- but my other gear isn't that great, my standards are higher for music on its own, and the room itself influences the sound. Music via bluetooth is more consistent, but has a slightly compressed sound -- perhaps because of the digital source or bluetooth itself.Are there ways to get more amazing sound or more volume? Yes, I've heard better stereos. For big parties a DJ setup with a PA would be more practical. But for the price and features this does really really well.

Bought this as a gap filler for my humble bedroom stereo while I save for higher end equipment. It’s driving a pair of Klipsch RB-51 II bookshelf speakers, primarily playing downloaded lossless ALAC files from my phone through the USB-C input.THE GOOD: It feels and looks to be well made. There’s no rattling, loosely fitting pieces, or gaps between panels. The matte finish is attractive and satisfying to touch. The VU meter and the warm white color of its light speak to the vintage hi-fi lover in me. For near-field listening at lower to moderate volumes, this little guy is surprisingly dynamic and has enough power for the type of listening I plan to use if for. The highs are crisp without being harsh, and the lows are punchy and accurate. The mids are pleasantly expressed by themselves but do ”sag” a little and turn a bit hollow when there is more going on in the mix. However, I have had similar experiences with other amps and believe the speakers are more to blame there. Connecting by Bluetooth is simple and intuitive. The sound quality takes a noticeable dive, but nothing more than what is expected with any Bluetooth connection. After 3 hours of playing music at a moderate-to-high volume with the treble increased to about 75% and the bass tuned up to roughly 60%, the unit was still cool to the touch.THE BAD: It is a bit of what I expected from a small, cheap, class-c amplifier. When I choose a song with a lot going on in the low end and turn the volume up to “fun”, the amp shows its lack of headroom and sounds fatigued. The sound imaging fades, the highs and mids are pushed back, and I get some distortion. I suspect the power delivered is nowhere close to the claimed power rating, as these particular speakers are rated for 75W RMS/300W peak, 8 ohms nominal impedance, and have a 92dB sensitivity rating.THE VERDICT: I’ve been listening to music through this amplifier for about 6 weeks now and I don’t regret my purchase in the least. In fact, this little amp surprised me a bit and exceeded my expectations for the temporary budget solution I intended it to be. I would gladly buy it again. Just don’t expect it to sound like an amp 3x its price and you won’t be disappointed.

This Gem of an amp is a great performer. I have tried it with a huge pair of Wharfedale E-90 tower speakers and they sounded amazing. Next, I connected the amp to a mini pair of Micron speakers. I got the same results. The next set of speakers I tried were a vintage pair of JSE model 1. Unlike the Wharfedale speakers the JSE are not efficient. The Fosi amp handled them perfectly! This amp has a pro look and the build quality is awesome. The switching between inputs is flawless. I found connecting to Bluetooth was very easy. I have used my cell phone as well as my mp3 player to stream. My Nad cd player sounded great. This 2.2 pound powerhouse is also small. 13.89 x 9.25 x 3.62 inches. The only thing I would like to see on the amp is a 1/4 " headphone jack I own a super pair of Grados and I would love to hear what they would sound like on the Fosi. This amp is a winner.

After reviewing many you-tube reviews on this amp, I was a little concerned as to the overall quality of this amp. I have the Fosi za3 and like it very much but I really need Bass and Treble controls. So, I decided to give this amp a shot as over the years, I have really enjoyed Fosi amps.Upon receiving the unit, I realized first hand that this amp was built like a tank and very heavy. It has all the inputs you will ever need including Bluetooth and usb-c for computer input. At 7.5 inches wide and 5 inches deep and 2.5 inches high, it is the biggest amp I have ever purchased for my desktop. I must say it has a beautiful finish with a VU meter and Bass and Treble controls with the copper knob that serves at the on/off control and volume.The power is indeed enough for me with the included 32v power brick.....believe me, you will not need the 48v brick. This thing runs very cool to the touch and looks bold and most stylish. Needless to say, this big boy occupies a good piece of real estate on my desk. It's a keeper for sure.....Give it a try, I don't think you will be disappointed.

l tried this and what a disappointment. No where near the power it says it has. Not worth the price, no remote and tinny sound. I wanted to save room but for $189 I rather buy a full size Sony or Yamaha. Lesson learned this is not a high quality product, this is a $40 dollar amp at most !
