Features

    Compact Yet Powerful The V3 mini power amplifier combines a minimalist design with exceptional performance. With a power output of up to 600W, it can effortlessly drive 2-8Ω speakers, delivering impressive sound quality. Its compact size makes it suitable for various applications, from bookshelves and desktop setups to home theaters

    Audiophile-Grade Components It features the TPA3255 high-end digital class D amp chip and utilizes premium Japanese NCC, ELNA, and German WIMA capacitors, and Japanese Sumida inductors for exceptional audio quality. With a SINAD rating of up to 88dB, an SNR of up to 110dB, and a low noise floor of only 140uV, it delivers exceptional clarity and low distortion

    Innovative Cooling The V3 stands out with its groundbreaking heat dissipation design. Equipped with vents on the casing's top and bottom, and a whole-body heatsink design, it efficiently dissipates heat, preventing damage to components and ensuring optimal performance

    Scalable and Fun Tailor your sound experience by swapping the stock NE5532 op-amps. V3 is compatible with a variety of 8-pin dual op-amps like Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4559, LM4562, LME49720HA, etc

    Note The "Pre-out" level is NOT controlled by the volume control as the V3 is not an integrated amplifier, so the sound is NOT adjustable when you are connected to the "Pre-out", and it doesn't come with the orange knob

Don't believe the 300 watt claims of the manufacturer. (I don't know why they just don't rate the amp with RMS real world specs). Still the Fosi Audio V3 is an excellent amplifier when paired with the optional 48V power supply, although it increases the cost. With the supplied stock power supply, the amp can deliver about 30 watts of real power and with the 48V power supply it can deliver about 80 watts of unadulterated bliss. The sound is clean with absolutely no hiss. You can tailor the sound by easily replacing the socketed OpAmps inside the amp, just make sure you insert them with the proper polarity. OpAmps can range from several to over a hundred dollars for a set. Better OpAMps can give you better depth and a wider sound stage as well as a mellower sound.Remember this is a no frills amplifier with only pair of inputs, it is basically a volume knob and nothing else. But this is perfect when used as a desktop amplifier to drive a pair of desktop speakers. In this mode of operation, you do not need the optional power supply since most desktop speakers are quite efficient and do not need much power.The 48V provides a more heft to the sound with the added power. It can easily deliver enough power to drive most speakers. With either power supply, the amp seems capable of driving even 4-ohm loads without distortion which most modern amps fail to do.Some Pros:* Cheap but great value* Compact size* Very efficient* Swappable OpAmps* High quality components: Elna capacitors, WIMA Output capacitors, Sumida inductors and NCC CapacitorsSome cons:* Fosi used to supply the amp with the copper volume knob as well as the black one but it is now an added option.* The amp goes to sleep rather quickly after the input signal is cut. It takes about six seconds for it to come alive when signal is restored.* There is only one pair of RCA inputs* No Bluetooth capability* No subwoofer output
