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

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.

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.

I use this with my Mac Desktop and my Bose desktop speakers and the sound is surprisingly good, good product

Great sound, ideal to pair with good bookshelf speakers like Dali Spektor 2 or similar.

Had all the connections we needed; sounds great and looks lovely on the desk too.

Dopo che il mio vecchio impianto audio 2.1 è passato a miglior vita ,ero indeciso se acquistarne un altro o di utilizzare delle Polk audio M10 con un mini amplificatore, che non ingombrasse troppo la scrivania e che riuscisse a farle suonare decentemente. La mia decisione è caduta su questo Fosi Audio per via delle innumerevoli porte di ingresso e la capacità di utilizzare sia un subwoofer attivo sia uno passivo. L'uso è prettamente per video game , ma ogni tanto anche musica di ogni genere. Il piccoletto mi ha meravigliato di come riesce a gestire queste Polk audio, con un suono pulito, con voci limpide, bassi profondi. Accordi di chitarra e basso elettrico sempre ben definiti. Nella capacità di gestire queste casse è nettamente superiore allo Yamaha A-S201 ,dove iniziava a farle lavorare dopo il 40 di volume, ma con una sonorità inferiore . Lo consiglio a chiunque, dall'uso pc al home theatre 2.1 in stanze di piccole metrature. PS: il piccoletto con l'alimentatore da 36V riesce a farvi litigare con i vicini di casa senza andare oltre il 75% del potenziometro del volume .

Ten sprzet jest OK w segmencie wzmacniaczy typu D do uzytku w biurze firmy czy sypialni jednak nie moze zastapic klasycznego wielkiego wzmacniacza klasy AB w salonie na co pewnie licza niektorzy entuzjasci hifi :) Nie to nie jest ten dzwiek choc jest nawet calkiem blisko panowie DAC tego fosi audio MC351 nie jest tak muzykalny czy analityczny jak AKM czy ESS i tu widze wade tego wzmacniacza... Dokupiono extra zasilacz 48V 5A ale nie dalo to zadnych extra muzycznych efektow w porownaniu do 32V dostepnego oryginalnie w pudelku. Muzyka poprzez BT z iphone nie jest tak wyrazna jak z CD ale nie ma co narzekac bo w tej cenie to calkiem dobra oferta. Jesli ktos ma niezlej klasy stare kolumny ktore kurzyly sie na strychu to mozna brac spokojnie MC351 bo spelni swoja role. Elegancka obudowa i bardzo dobra jakosc wykonania ale pozbawiona otworow wentylacyjnych czy malego wiatraka... _____ Czekam z niecierpliwoscia na nowa wersje tego modelu z lepszym DAC na pokladzie bo sam projekt jest trafiony ale jak to zawsze bywa troche niedopracowany w pierwszej wersji chipset... apdejt: dokupiono zewnetrzny DAC od fosi model ZD3 i jest lepiej ale plyty CD zagraly zauwazalnie piekniej dopiero po podlaczeniu transportu sony x800 m2 poprzez coax ,prosze zwrocic uwage ze ten sony to dzis najtansza opcja na SACD w amazon

Super Verstärker und auch hübsch anzusehen. Macht richtig Dampf. Leider keine Fernbedienung dabei. Ansonsten tip top und super verarbeitet.

Having used a Sony str 780 AVR 7.1 set up for years I have become fed up with its size & constant hdmi battles, I longed for a simple plug & play set up. I hooked up this bad boy up to my old set of gale silver monitor speakers (6ohms 100w) and a gale 10 sub (100w) using chunky cabling drawing sound output via hdmi from ps5 to lg tv then optically to this unit. Initially playing gran turismo on ps5 felt a bit mono (I suspect it’s because I’ve been used to 7.1. After some fiddling & cranking it up it really delivers. Clear 2.1 sound, Plenty base (more than what my Sony does on 2.1 stereo mode tbh. Connected my astell & Kern audio player via BT & let enya, Phil Collins & some high def lossless tracks do their thing.. woah! If it’s a good quality sound it’s great & crisp & clear. iTunes music varies greatly & Tron soundtrack is great whereas casino royale soundtrack sound awful. To sum up this is a great unit for the price, it gives be a really good sound (harking back to my student days of cheaper end hifi equip etc). BT connection really strong, just make sure your music content is good quality (iTunes utterly butchers some albums). Only thing I wish this had was a remote control. I’ll be putting this unit (& my gale set up in our lounge for tv). Also off the back of this purchase I’ve purchased a Fosi ht4 4.1/5 channel unit for my man cave to replace my Sony str 780. Can’t wait!! Well done Fosi.
