Fosi Audio MC331 Tubes Integrated Amplifier JAN5654W Bluetooth 5.0 2x105W 4 Ohm
The Fosi Audio MC331 is a powerful little hybrid integrated amplifier based on JAN5654W tubes and a TI TPA3221 chip. This little jewel blends modern and vintage technology, and is capable of delivering up to 2x105W of power under 4 ohm, enough to soundtrack a beautiful space.
In addition to its RCA input, it features numerous digital inputs (USB-C, Toslink optical, coaxial SPDIF), as well as Bluetooth 5.0 functionality for reliable, stable wireless transmission thanks to a proprietary DAC/Bluetooth chip. There's also a 3.5mm pre-out jack for coupling to an active subwoofer, and a 3.5mm headphone output on the front panel.
Highly versatile and elegant, Fosi Audio has given its MC331 amplifier a stylish appearance, with a round vumeter and transparent glass tube protectors. The user experience is further enhanced by an infrared remote control.
Fosi Audio MC331: JAN5654W tube preamplifier & TPA3221 TI amplifier
The MC331 combines a pair of JAN 5654W tubes and a TI TPA3221 chip to deliver warm, powerful sound with 2x105W output power at 4 ohms. This amplifier is therefore capable of providing a considerable amount of sound, coupled with suitable speakers. What's more, its 3.5mm pre-out jack output makes it easy to set up a 2.1-channel system with an active subwoofer. JAN 5654W tubes are interchangeable with many other models: 6AK5, 6AK5W, 6Zh1P, 6J1, 6J1P, WE-403A, 403B, EF95 and many other 7-pin tubes. This makes it possible to achieve the desired sound coloration.

Thanks to its 3.5mm jack output, the Fosi Audio MC331 can drive headphones or IEMs with impedances ranging from 32 to 300 ohms. Extremely practical when placed on your desk, for example.
Fosi Audio MC331: Bluetooth 5.0
The Fosi Audio MC331 features Bluetooth 5.0 functionality to ensure reliable, stable reception of an audio signal. It supports AAC and SBC codecs.
Fosi Audio MC331: Retro look and tone control
The Fosi Audio MC331 features an attractive round vumeter on its front panel, as well as two transparent glass tube covers contributing to the retro look of the Fosi MC331. In addition, 3 potentiometers on the front panel control volume, bass and treble tones to fine-tune the final sound.
