P Zero

About the P Zero

The Audio Note UK P Zero are monoblock tube power amplifiers, each producing approximately 8 watts of output power. They use two ECL82 (also known as 6BM8) triode-pentode tubes per channel, running in Class AB2 with the pentode sections in ultra-linear push-pull mode. The triode sections serve as input amplifier and phase splitter, with a driver transformer likely employed. The amplifiers are compact and lightweight, housed in extruded aluminum chassis, and designed to provide a balanced, natural, and detailed sound with good bass, midrange, and treble balance. The P Zero amps are part of the Audio Note Zero series, which emphasizes sonic performance over technical specifications, featuring high-quality custom output transformers and a minimalist design ethos. They are typically paired with Audio Note AZ-Two speakers and other Zero series components such as the M Zero preamp and DAC-Zero processor. The P Zero amps have RCA inputs and are designed for use with Audio Note's own cables due to closely spaced RCA connectors. They are known for their musicality, texture, and dynamic response, making them a compelling entry-level tube amplifier option within the Audio Note lineup.
