The First Watt J2 is a high-performance audio amplifier circuit designed by renowned audio designer Nelson Pass. It is a single-ended design with a power output of 12 Watts into 8 Ohms or 24 Watts into 4 Ohms. The J2 is known for its in-house made low noise op-amp, J1, which is used to drive the output stage. Its design goals include low noise, low distortion, and generous headroom. Additionally, the circuit uses a custom output transformer designed specifically for the J2, which is said to provide a unique sonic signature with excellent bass performance. The J2 is hand-built in the USA by First Watt and is widely regarded as one of the best audio amplifier circuits available in the market.
