High-End Audio (Hi-Fi) Components: JFETs

JFETs are key elements in high-impedance devices like MEMS sensor buffers, microphone preamplifiers or Moving Magnet (MM) phono preamplifiers. (Don’t misfit with MOSFETs!). Nevertheless, there are somehow controversial components for Hi-fi aficionados. Generally, BJTs high […]

Op-Amp: an Audio Purist Public Enemy?

Op-amps are used everywhere today, especially in audio design because of their outstanding price-performance ratio against discrete components. But in the premium audio purist world, op-amps are often considered as little daemons, children of the […]
