Calyx Femti 125 Triple Mode Amplifier


The Calyx Femti is a dimunitive power amplifier that is a visual match for the 24/192 DAC.


  • Calyx Audio’s new Femti stereo power amp is a stunner. Versatile, dynamic, tonally neutral and with iron- fisted control. The amp has three modes of operation.

    1) Standard stereo rated at 125wpc.

    2) Dual mono with one amp driving one bi-ampable speaker.

    3) Bridged mono with each amp rated at 500wpc. 

  • The Femti delivers 125 watts per channel into 4 ohm loads (and presumably half of that into 8 ohm loads), and 500 watts in bridged mode operation. A tricolour LED indicates normal operation, short circuit, and overload conditions.
