Schiit Audio Introduces Aegir 2 Speaker Power Amp

Schiit Audio introduced the second generation of its Aegir speaker power amp, Aegir 2, bringing its mixed voltage and current feedback Halo topology to a speaker amp for the first time. Schiit found that this topology provides significant enhancements to the original Aegir’s performance, now combined with the company's Continuity output stage which enables higher power output, less heat, and lower noise floor.

Linear Integrated Systems, the world-class designer and manufacturer of precision, high-performance, small-signal discrete semiconductors, announced the release of its 2022 Small Signal Discrete Data Book. The Data Book provides all Linear Systems’ datasheets in one spot. The Table of Contents includes product category, part number and part description, so users can browse the entire product line with ease. There is also a dedicated section on packages, highlighting the latest package innovations and packing options.

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.

In this simple amplifier project, Ed Simon describes a Class-A amplifier design that mainly intends to reproduce music with reinforced emotional expression. That's what you normally get with a quality design, but to achieve it, the author shares the complete concept, power requirements, circuit topology, construction and testing of this single-ended amp... in a solid-state design. This article was originally published in audioXpress, April 2006.

This article continues the classic JFETs series of articles by Erno Borbely and introduces one of his starter kits with an all-JFET line amp. Originally published in audioXpress March 2005 this is an essential reading to understand the “building blocks” of the “Borbely amplifiers”.

The basic circuits on which Erno Borbely based most of his projects are described in “JFETs: The New Frontiers, Part I and II,” published in Audio Electronics AE 5/99 and 6/99, and “All-FET Line Amp,” published in audioXpress May 2002. As the author admits, these were the “building blocks” on which many - if not all - of his amplifiers are based. This articles continues his JFETs series and was originally published in Audio Electronics, Vol 5 1999.

The basic circuits on which Erno Borbely based most of his projects are described in “JFETs: The New Frontiers, Part I and II,” published in Audio Electronics AE 5/99 and 6/99. Referring to these articles frequently, the author admits, these were the “building blocks” on which many - if not all - of his amplifiers are based. This article is the first part, as originally published in Audio Electronics, Vol. 5 1999.

What can you do to ensure the best possible sound from your system? According to Nelson Pass, the “sweet spot” concept is generally regarded as “that happy balance of conditions that elicits the best possible sound,” including the interiors of the components themselves.
