Charcroft Launches ClarityCap Purity High-End Audio Capacitors

Charcroft Electronics, the specialist distributor and manufacturer of electronic components, has launched the Purity range of ClarityCap audio capacitors to deliver a significantly lower noise floor, with more ‘dark space’ around the audio signal, and an improved dynamic range. These features enable greater clarity for audio reproduction as well as improved spatial separation for the individual instruments and vocals. The new capacitors use the multi-strand Van den Hul cable specified by high-end loudspeaker manufacturers.

Build a Discrete High Output Current Buffer with JFET Input

This article from Dimitri Danyuk explores ways to provide better isolation between input and output terminals and lower input noise current using JFETs from Linear Integrated Systems. For unity-gain buffer applications there are many open-loop IC buffers on the market based on bipolar technology. They are mostly complementary emitter followers connected in series. With the appearance of complementary JFETs from Linear Integrated Systems, it is possible to construct a discrete buffer with JFET input.

Searching for a Unicorn Part 2: Generating a Good Signal Source

In this second article, Brian Lowe (Belleson LLC) continues his search for the Unicorn of "Measuring Voltage Regulator Ripple Rejection," this time focusing on the test fixtures. Testing a voltage regulator with exceptionally good performance requires an even more exceptional signal source and measurement setup to measure sub-microVolt ripple across a wide frequency range. Complementing the final article, Jan Didden, offers an informative sidebar about super regulators. This article was originally published in audioXpress, June 2019.
