Premetto che sono un audiofilo da oltre 40 anni e ho avuto anche impianti di un certo livello. Da un pò mi balenava in testa di ripristinare le vecchie Linn Tukan, diffusori audiofili ovviamente passivi, che ascoltavo in ambienti piccoli tantissimo tempo fa e tenuti conservati. La scusa è venuta appena ho cambiato il PC assemblandone uno da desktop di ottime performance. Già in possesso di un discreto DAC Topping DX1 collegato alle classiche Empire in legno amplificate, mi mancava un ampli per pilotare le piccole Linn...piccole ma diffusori "duri", 87 db di efficienza. Su consiglio di un amico acquisto Il Fosi V3.....Risultato?...Sorprendente....il problema non è tanto la capacità di pilotare carichi non facilissimi, quanto la qualità del diffusore che non perdona nulla...Il Fosi è incredibilmente di qualità , non voglio dire Audiophile in senso strettissimo (ma mi riservo di provarlo nell'impanto principale) , ma riproduce il suono in maniera trasparente, dinamico, senza incertezze , senza scomporsi e senza riproporre un suono confuso (tipico degli ampli di scarsa qualità)...ripeto, vi garantisco che le Linn Tukan sono diffusori di eccellente qualità....non perdonerebbero amplificazioni scarse....a questo prezzo il risultato e a dir poco sorprendente....altamente consigliato per impianti desktop con aspirazioni audiophile.....

He adquirido otros amplificadores FOSI clase D, y no me han decepcionado. En mi caso para cadena de audio que he ideado. Mediando como cerebro un WiiM Ultra. Alimentando de señal a otro amplificador fosi -M01 BT MONO SUB AMPLIFIER-para mover un Dayton Audio BST-300EX, 300 vatios RMS, agitador de graves táctil, impedancia de 4 ohmios, aparte la misma salida DE subwoofer del WiiM ultra alimenta señal para un subwoofer activo Yamaha de 250 watts.A su vez, en esta cadena va conectado un procesador de campos sonoros Yamaha, producto Vintage de excelentes prestaciones.Y para esto , este aparato requiere de 4 a 6 canales de audio, lo tengo a 4 canales con otro amplificador FOSI. EN ESTE PEDIDO : este Amplificador Fosi Audio V3, es Amplificador estéreo de audio para el hogar de 300 vatios x2 de potencia TPA3255 clase D Mini amplificador de altavoz 2 canales. En este caso lo pedí con su Power Adapter 48v/5A. Es un "monstruo" más grande y pesado que el mismo amplificador Me agrada su aspecto minimalista,con un solo botón para encender (hace "clic") y manejar el volumen Y si , lo esperado, se calienta, yo digo lo normal. Escribiré posteriores opiniones según se vayan portando estas pequeñas bestias amplificadoras

This is an excellent amplifier. I bought two of them to drive PSB desktop speakers and Kanto speakers in my dining room. They are no-frills and perfect for driving with WiiM streamers. They are compact and stack nicely with other small components like the WiiM Pro and a headphone DAC. The amplifier has plenty of distortion-free power and punch, and will drive speakers very loudly when needed. I really like Fosi audio electronics.

Sound quality was great, especially when paired with P3 tube preamp from Fosi. I heard layers and depth with musical beauty I had not heard before. However, it came with defective power on/off switch. Poor design when it is integrated into the volume knob. It just would not turn off (light stayed on and Fosi confirmed it was a defect) and made strange repeated clicks inside the unit after turning the volume knob into off position past the off click. Also, turned on once by itself. Unsafe. Contacted Fosi support which was a waste of time. They confirmed it was defective. They kept trying to help ‘remotely’ and had me going in circles doing all kinds of waste of time tests and sending emails and endless videos. You cannot solve a hardware issue of this type remotely. What I wanted was an exchange with Amazon, as I returned the defective item. I bought it on Prime day, but price had gone up significantly after. But they said I need to buy it again and then submit a request later for the difference. Super inconvenient. I expected an exchange or discount coupon to buy it again. Not sure if I will buy again. Maybe will go with Aiyima A07 Premium since it has a physical power on /off switch separate from volume knob.

Worth every penny. Powering dali tower speakers in a dolby atmos setup while avr is powering up the rest of the speakers. Noticeable improvement in clarity and bass of the towers. I wanted to reduce the load on my denon AVR and so far i am happy with my purchase.
