Analog Sound Experience with True Tube Amplification:

The Fosi Audio P3 is a tube-based preamplifier that blends the warmth of analog audio with digital precision. With a 54V operating voltage, the included 5654W vacuum tubes work at full potential, delivering a rich and natural sound with detailed mids, sparkling highs, and deep bass. This preamp excels in reproducing music with character and depth typically found only in high-end equipment. Thanks to its unique preamplification technology, the audio signal remains clean and dynamic—ideal for both passionate listeners and discerning audiophiles.

High-Resolution Bluetooth Streaming:

Equipped with Bluetooth 5.1 and the powerful Qualcomm QCC3031 chip, the P3 supports aptX, aptX HD, and aptX LL for high-quality wireless audio with ultra-low latency. Perfect for music, video, or gaming, it offers freedom to stream from your smartphone, tablet, or computer without compromising sound quality. A convenient reset button makes it easy to remove previous connections and prevents unwanted pairing. The stable wireless range extends up to 10 meters, making the P3 a flexible centerpiece in your setup.

Ideal for Both Speakers and Headphones:

The P3 functions as both a preamplifier and a headphone amplifier. It supports headphone impedances from 16 Ohms to 300 Ohms, making it suitable for everything from IEMs to full-size HiFi models. You can also connect active speakers, an external amp, or create a 2.1-channel system with a subwoofer using the RCA, AUX, or 3.5mm outputs. No matter the setup, the P3 delivers a strong, clean signal with minimal noise and distortion—equally at home in desktop setups or full HiFi systems.

Tone Control and Premium Component Quality:

Fine-tune your sound with bass and treble controls featuring center detents for easy reset to neutral. If you prefer uncolored sound, both controls can be centered to bypass the tone circuit. Inside, the P3 features premium audiophile components such as ELNA capacitors and taper A potentiometers, ensuring reliable performance and long lifespan. Technically impressive, the P3 offers a signal-to-noise ratio of =103 dB, total harmonic distortion of =0.02%, and a dynamic range of 104 dB—all housed in a solid, compact design that pairs perfectly with other Fosi Audio gear.
