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.
Power @ 8Ω
330W
Power @ 4Ω
660W
Power @ 2Ω
1320W
Slew rate
> 1300 V/µs
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.
