SenseV1 headphone amplifier

Description
Sense V1 is a pure class-A VMOSFET headphone amplifier. VMOSFET has high working frequency, low noise, good thermal stablility. The harmonics of VMOSFET are even order, so much like vacuum tubes. That's why the sound of VMOSFET is like tube amplifiers. Design of V1 has no global feedback to features more natural sound. It use hifi components such as Alps potentiometer, WIMA caps which are usually used on expensive high-end amplifiers.

Hi,

Anyone know the output impedance on the headphone output? Thanks.

The fet output stage makes the impedance very low. It can drive 32 Ohm to 600 Ohm headphone very well. It even works fine for 8Ohm speaker.
