Fosi Audio V3 300W x2 Power TPA3255 Mini Amp 2 Channel Class D Stereo Amplifier for Passive Tower Speakers for Home Theater Desktop Shelf Tower with 48V Power Supply

I bought the Fosi Audio V3 primarily to use in my cymatics setup, and so far I’ve been very impressed with it. For such a small amplifier, it has plenty of power and drives my setup confidently. What matters most for cymatics is having clean and controlled output across different frequencies, and the V3 has worked very well for this. Frequency sweeps feel consistent, and I’m able to get strong, well-defined vibration patterns without needing a large traditional amplifier. I also really like how simple the V3 is. There are no unnecessary features or complicated controls – just a straightforward amplifier that does its job well. The aluminium enclosure feels solid and premium, and its compact size is particularly useful in an experimental setup where I already have other equipment, cables and the cymatics apparatus taking up space. It can get warm during extended use, which is something to keep in mind, but I haven’t found it to be an issue so far. Overall, I’m very happy with the Fosi Audio V3. My use case is probably quite different from the typical hi-fi speaker setup, but for powering my cymatics experiments it has been an excellent little amplifier – compact, powerful and easy to work with. Definitely recommended.

What to say? This little powerhouse sings well! Powers my DIY 3 ways sufficiently, I have a more powerful diy amp which is just gavering dust, as this little puppy serves me well!

Good i am using this as an dual subwoofer setup for denon x1800h av receiver using this for 2 weeks no issues working good, no distortion sound/humming issue

The chassis is sleek, minimalist, and solidly built. The V3 has impressive amplification capabilities. It drives speakers maintaining clarity and dynamics. The sound signature is clean, transparent, and free from distortion.

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.

I am driving a 94db efficient speaker. However it lacks punch and midrange is very laidback to the extent it keeps me wanting more from the amp.

Sound quality not good

First, I’d like to point out I’m not audiophile. My hearing was damaged a long time ago during my teenage years attending multiple live events. Front row at the White Stripes concert will do that to you. I regret my carelessness in not wearing earplugs. I also regret listening to my Aiwa Walkman at loud volumes for many many years. I was looking for a small amplifier to power my Energy bookshelf speakers. The advertise specs of 300 watts x2 power is a bit of a bait, a joke as one might say. 300 watts is possible only with a 48v, 10A power supply on a 4 ohm load. The majority will be running 8 ohm speakers, with the 5A power supply, it will push 115 watts per channel which is more than enough. I prefer companies who under rate their products. Under promise, over deliver is something I live by. The packaging was adequate, but I didn’t care for the box design. HiFi Made Fun and Home Audio Expert written on the box seems cheap and amateurish. I would suggest all black, no wavy design, no slogan, only Fosi Audio written in plain white text. Make it simple just like the design of the actual amp itself. Inside the box, the amp and the power supply were arranged neatly with adequate foam protection. The best part of the amp is the sound. Upon turning on the amp, no pops, no hiss can be heard, absolute silence, like death. Good so far, I loaded Pink Floyd the dark side of the moon album and my jaw dropped. Ok I get it. I get the hype. This is it. The sound, the tasteful simplicity, no tone control. Turning the volume knob to the max doesn’t distort. It only comes alive with the sound of music. Very impressive and highly recommended.

I'm a music lover and this makes one of my favorite music devices. Delivers the best sound quality for me. Recommended.

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.

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

Wie dieses Teil die Lautsprecher befeuert und vor allem unter Kontrolle hält ist einfach genial. Ich habe den Amp mit Klipsch RP 8000 F , MB Quart , Canton Ergo 900 DC , Heco Fidelity getestet. Super. Netzteil mit 48V verwendet. Spielt in einer viel höheren Liga. Da rauscht nichts. Der Hintergrund ist einfach nur schwarz. Stereobühne perfekt. Der Kaufpreis ist schon fasst unanständig niedrig. Kaufen Leute.
