Product details

The Fosi Audio P3's preamplifier circuit raises the voltage to 54 V, ensuring that the tubes realise their full potential and deliver a warm and rich sound experience. The unique pre-amplification technology delivers pure audio signals that faithfully reproduce crisp highs, full mids and deep, rhythmic bass. Equipped with the Qualcomm QCC3031 chip, the P3 preamplifier enables impressive wireless sound quality and low latency, with compatibility for aptX HD and aptX LL codecs. The P3 offers Bluetooth/RCA inputs and RCA/AUX-OUT/3.5 mm headphone output. As a headphone amplifier, it supports headphones with an impedance of 16 to 300 ohms. The P3 uses ELNA audiophile capacitors and Taper A Pot. The bass and treble controls have central locking mechanisms.
