The Nobsound P32 is a tube headphone amplifier delivering an output power of 1000 mW into 32 Ω, compatible with headphones with an impedance of 24 to 600 Ω. Its tube stage provides a warmer sound, while the signal-to-noise ratio of ≥ 110 dB and the frequency response of 20 Hz to 30 kHz preserve the accuracy and stability of the listening experience.
Designed to evolve with the system, the P32 features interchangeable tubes and operational amplifiers, allowing its sound signature to be gradually adjusted without replacing the unit. This architecture thus combines headphone amplification, sound customization and a preamplification function within a single device.
The Nobsound P32 is a tube headphone amplifier delivering an output power of 1000 mW into 32 Ω. Compatible with headphones with an impedance between 24Ω and 600Ω, it can drive both sensitive earphones and high-impedance models while maintaining a dynamic sound. Its tube stage provides a warmer sound signature, while the signal-to-noise ratio of ≥ 110 dB and the frequency response of 20Hz to 30 kHz help maintain a detailed and quiet listening experience.


The tubes and operational amplifiers of the Nobsound P32 are interchangeable, allowing the sound to be gradually adapted to the components used. This scalable design offers the possibility to explore different sound signatures without replacing the entire unit, while keeping the same amplification and preamplification platform.
