Très bon amplificateur

Branché sur des jamo alto signature il est très bien. Il pourrait être amélioré sur les aigus. Un peu trop cristallin. Heureusement les réglages permettent de compenser. Mais attention pour ce rapport qualité prix c'est très très bien. Une vrai amélioration serait de le rendre wifi. Son est meilleur en wifi branché sur source avec beaucoup plus de puissance.

Surprising BT20A

I hooked this little amp to Magnepan MMGs That I was trying to sell. I ran the amp all day and it was just barely warm using the 48 volt power supply. The Bluetooth connected easily and I had zero drop outs. Later I hooked up a pair of Martin Logan ESLs. The customer, an experienced audiophile, gave a careful listen and took them home.

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 glazbu daje. Posjedujem pojačalo Rotel koje sam platio 1650 eura i mogu reći da ovo malo "čudo" nimalo ne zaostaje po pitanju kvalitete zvuka. Sve čestitke tvrtki Fosi Audio na ovom divnom malom čudu!

Neat little amp

Neat little amp which does exactly what it claims to do. I'm using it with some old 8 ohm speakers, not the most sensitive but it still manages to drive this just fine.
