"hifi"

the mc331 was about to be a great piece of equipment, but at low volumes there is very distinct clipping that completely ruins any fidelity gains.

A wonderful little marvel of technology

Nine days after ordering, I received the shipment with the Fosi MC331 amplifier. Everything was properly and nicely packaged. I easily assembled it, turned it on, and connected it to my phone, then connected my AKG K702 headphones. I was pleasantly surprised by the fantastically beautiful sound, which was clean, clear, and warm. I connected it to my home speakers, Wharfedale Diamond 250, which it powered without any issues. The sound on them was like 'a fairy tale.' It's hard to believe that so much power can be packed into such a small package and deliver music so faithfully. I own a Rotel amplifier that I paid 1650 euros for, and I can say that this little 'marvel' hasn't fallen behind in terms of sound quality. Congratulations to Fosi Audio on this wonderful little marvel!

Divno malo čudo od tehnike

Nakon devet dana od narudžbe dobio sam pošiljku s pojačalom Fosi MC331. Sve uredno i lijepo zapakirano. Lako sam ga sastavio, uključio i spojio s mobitelom, zatim priključio slušalice AKG K702. Ugodno sam iznenađen fantastično lijepim zvukom koji je čist, jasan i topao. Spojio sam ga na svoje kućne zvučnike Wharfedale Diamond 250 koje je bez problema pokrenuo. I na njima je zvuk ko' "iz bajke". Čovjek prosto ne može vjerovati da se može u tako malom pakovanju staviti toliko snage koja tako vjerno glazba daje. Posjedujem pojačalo Rotel koje sam platio 1650 eura i mogu reći da ovo malo "čudo" nije zaostalo po pitanju kvalitete zvuka. Sve čestitke tvrtki Fosi Audio na ovom divnom malom čudu!

Still haven’t received item

Exactly what the title says, I still haven’t received the item. Ordered 16 days ago, and I am still empty handed. IF I ever order another Fosi product, I will order it from Amazon
