Understanding the differences between balanced and unbalanced interfaces, and best practices for interconnecting balanced and unbalanced equipment, is important for achieving optimal audio performance and minimizing noise issues.
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 […]
Capacitors come in two main types: electrolytics and non-electrolytics. There are not ideal elements, less to say, and intrinsically present Equivalent Series Resistance (the famous ESR), current leakage, dielectric absorption and, as usual with real […]
Resistors have two main issues when you want to design a low noise, low distorsion system : noise and linearity. Imagine also that you design a RIAA filter : tolerance and linearity are major concerns […]
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 […]
