    Wow - Just what I needed and I didn’t know it!
    So small and cute looking, even my wife likes it. Great power to drive my needy M&K 4ohm K17s in bookshelf set up in my garden room. TV source uses the optical in, Bluetooth in for kids and family tablets etc. I use the OTG usb input from iPhone/Amazon music which gets best out of Fossi DAC. Not used RCA yet, but have a feeling my record deck may be moving soon. So happy with back to basic switching between sources, the tactile treble & bass tone controls and larger volume wheel. The VU display is the icing on the retro cake. Not used .1 yet, but I do have a simple vintage M&K K10 sitting in garage waiting to be used as active sub for the mini jack output. (Ignore the Devialet soundbox in pics - which is soon to be in the garage). Thank you Fossi. Will add update report after medium/long-term use.

      Purchased to use with some Wharfdale 12.1 speakers in my study. Sits on my desktop, playing music from the PC via optical and from my iPhone via Bluetooth. I'm no audiophile, but for the price, this sounds wonderful to me. I tried the Fosi MC331 first (I liked the look of the valves). However that suffered from strange cutting to silence in quiet sections of music - so returned. This is brilliant in comparison though.

      Looks great. Amazing functionality as I use this for my ps5, Spotify over bluetooth and vinyl.

      I have paired with a high quality pre amp and that makes all the difference.

      Used this, in conjunction with the Fosi audio box2 pre amp to power a Technics record deck and a pair of 1980's KEF speakers, I was using a vintage amp which died, the sound quality has improved and I can link up my computer and phone via blue tooth for streaming music.

      I REALLY REALLY wanted to love this product because i think it looks the best by far for sub £200. But the right channel has intermittent crackling, it would come and go.

      I did a process of elimination to rule out speaker or wires and after doing that it turns out it was the AMP. What a shame. I have ordered another one, but if this one has any issues then i have lost massive faith.

      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...

      Reviewed in Australia on 14 September 2024
      A small device, in a quality metal case, with good basic functionality and decent sound reproduction. Lacking wifi connectivity, so no app to control it. Also, no remote control. Synchronizing your TV signal with the digital audio output (when using a USB connection from the TV) can be a challenge, leading to mismatch between video and audio (i.e. an obvious sound lag).
