Power amplifier · Class A/B

# The First

A power machine built to disappear. High current, negligible distortion, bandwidth
beyond the audible range: The First adds nothing to the signal, and gives everything
back.

Design philosophy

## High-current Class A/B. No compromise on control.

The output stage delivers 330 watts into 8 ohms and doubles down faithfully into
difficult loads. A fully balanced topology and generous power supply grant an impulse
response that the most demanding loudspeakers translate into real-world dynamics.
