Fosi AudioV3 Mono Power Amplifier for Home Audio Speakers, Mini Monoblock Class D Amp with TPA3255, 240W for HiFi Home Theater AVR Receiver Component, RCA/XLR Balanced Inputs 48V/5A Power

Wow is all I can say !!!I have a Denon H3700 AVR with Preamp Out. For my mains I use a pair of Odyssey Mono blocks and was dependent on the AVR’s internal amps to handle the center and surrounds. I was never happy with the center channels response, messed with Audussy and downloaded the MultiEQ app and was able to get it to an acceptable level, but never that happy.Read about this little guy and figured I’d give it a shot and WOW… once I dialed it in with the MultiEQ App I’m totally blown away.Basically this is just for my Surround Sound Applications and not for music being only listen to music in 2ch.Can’t recommend the V3 Mono enough if you want improve the center channel, so much better than the internal amp in your AVR. Keep in mind your AVR is using a single power source to power every channel, and every feature, seriously too much under the hood thus using your preamp outs utilizing external amps will give you much better sound quality and sound stage.In my case I’m still letting the AVR handle the Heights, Surrounds & Rear Surrounds being they only get limited info sent to them and the AVR’s amp is fine… Mains & Center Different Story!The Fosi V3 Mono totally worth every penny !

I bought two of these as an experiment to compare against five other dedicated amps that I own - (Adcom, Outlaw (80 pounds), Emotiva XPA, HK Citation, and Onkyo) -various models and years from 2022 to the 80's with the Citations. Coupled to the Topping D90 and the Topping P90 Pre Sabre and playing through a pair of Sonus Faber floorstanding speakers, my initial thoughts were that they were a bit too transparent and thin. I was confident.that my amps some costing over $1600 were superior and that I would shuffle these tiny monoblocks in a seperate surround system as drivers for Dolby Atmos channels. Well then I read about Sparkos opamps. I ordered four of the SS3602's and the story changed. Hard to believe but these little devils improved the presentation beyond my expectations. The clarity and tightness of bass is still excellent but the vocals seem insanely good- holographic. Incredibly I would even say that they sound better now than any of these other amps using this combo. I have learned that the synergy between preamps, dacs, amps, and speakers makes a big difference. An enjoyable hobby which now just got a lot cheaper!!

My vintage integrated amplifier didn't have enough juice to run a quad stack of vintage Advent speakers. I was preparing to shell out a few grand for a power amp but found these monoblocks are perfect for what I need. Very clean, powerful sound for the money.

This amp is being used to power an extra speaker I have to take the place of some poorly designed built in speakers on my bedroom TV. It works to power the speakers, however the AUTO feature is something you may not want to use since it has a very noticeable pop sound when it powers up fully. It seems best to set it to ON instead of AUTO.

These little amp pack a punch for their size. I needed an amp in my living room theater setup and decided to go Mono Blocks (just because). I have them connected to a Gustard R26 dac and they’re driving a set of Klipsch Heresy II’s. For giggle I brought them into my listening room to give them a listen. I connected them to my Parasound P6 preamp via XLR and wires them to my Dynaudio Evoke 50 floor standers - wow. They were clean and spot on, and like I said, pack a hell of a punch for their size.I have since lent them to a friend who had a channel in his power amp go out. He’s Driving Magnepans with them, and now seems IN NO RUSH to replace his power amp. Go figure! 😂I’d definitely recommend them.

I wasn't expecting this much from a device like this. I have two 12 infinity subwoofers that are dual voice coiled. My thought was to give these a try in the off chance they can actually push the sub. I tried both 8 and 2 ohm configurations on one subwoofer and I am really impressed. 8 ohm, the subs were happy, I would guess they were getting around 130-140 watts as expected. The damping is impressive with 8 ohms as everything sounded amazing and tight with true accuracy of the sounds it was able to produce. When I tried 2 Ohms, that is when I laughed out loud due to my shock on how much current this thing can produce! I'm not going to say it was crazy but it was truly getting there. I'm not sure if this can double the power at 2 ohms but it did seem to be producing more then 300 Watts RMS with ease. I have a 400 Watt RMS amp and this thing is right up there with it.My plan now is to get 4 of these and pin each amp to a voice coil to provide 480 Watts RMS (240W per voice coil) to each subwoofer. While it performed well at 2 Ohm I feel a 4 Ohm load might be a slight bit better on damping.For the price these things are absolutely amazing, I am now figuring out if I need to run a dedicated 20AMP service for my audio equipment cause these alone will draw 14 Amps when they hit. I'm pretty sure I will trip the circuit breaker on a 15AMP with the rest of my gear if I don't upgrade it.

He comprado ya 3 de este producto..... Estoy enamorado de el.... Amplifica muy bien.... No es tan costoso... Soy de Ecuador y es un producto que está a mi alcance.... Me preocupa que se calienta pero con una ventilación de muy abajo ruido tengo controlado la temperatura..... Los 2 primeros los compré para unos parlantes KEF LS50...... Me encantaron y me compré 1 más después para aumentar el sonido de mi parlante central del teatro en casa..... Igual un KEF.... Excelente compra.... Gracias
