Works well for its price point so far. Remains to be seen how durable it is.

A small amp but more than powerful enough for a desktop setup. It looks good and as a bonus has a remote

heb het gekocht als hebbedingetje maar werd er een beetje verliefd op,ziet er goed uit en presteert goed maar kom op mijn luidsprekers met erg laag rendement toch wat vermogen tekort dus wil toch een Fosi met meer vermogen aanschaffen

Fast, honest and cheap

Dit is weer een toppertje van Fosi Audio. Klinkt geweldig goed. Alles gecombineerd. Output is erg goed. Stuur er 3 weg systemen probleemloos mee aan. Memory selector. Geheel compleet met AB. Had een eerste productiemodel rechtstreeks van Fosi voor 100 euro.
