compact et puissant
Utilisé pour avec des enceinte spassives Q acoustics 2020i, après avoir tenté un TEAC et un Denon PMA60, le Fosi audio brille par sa puissance sans compromettre la clarté de la musique. Le son est beaucoup plus clair que sur les deux chaînes sus mentionnées qui m'ont coûtées 4 fois plus. Il ne chauffe pas ou peu. L'allumage se fait par le bouton de réglage du son, et celui-ci donne une bonne sensation de résistance (souple mais pas trop) lorsqu'on le tourne. Il y a un très léger crachement à l'allumage, mais pas de violent "pop", et aucun son à l'extinction. Equippé d'une sortie enceinte et d'une entrée RCA (je n'est pas testé la sortie "pre out"), il n'offre que le minimum syndical et nécessite une installation DAC/CD/PC pour lire du son, mais la différence de prix permet de se payer du matériel spécialisé beaucoup plus performant que sur les chaînes HIFI multitâches "tout en un". L'ensemble revenant beaucoup moins cher pour une qualité bien supérieure. II ne pèse que quelques centaines de grammes et tient dans la paume de la main, les câbles peuvent d'ailleurs le tirer vers l'arrière et c'est à prendre en compte dans votre installation. Quand l'appareil est éteint, le transformateur 48V reste allumé -prévoir une prise à interrupteur.

Eficiente amplificador clase D
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

Plenty of distortion-free power and punch -- highly recommend
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.

Questionable on/off switch design integrated into volume knob
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.

Value for money
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.
