JFETs: The New Frontier, Part 2

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.

It’s hard to keep track how semiconductor companies evolve given the pace of mergers, spin-offs and acquisitions. ON Semiconductor, a relatively young player in the industry but increasingly crucial for the audio industry, announced it will acquire one of the most iconic companies, Fairchild Semiconductor, for $2.4 Billion in Cash. The acquisition creates the global leader in the power semiconductor market, they say.

Which sounds better — a tube or solid-state amp? The "Great Debate" has been going on for decades. Now it's time to put the debate to rest. In audioXpress, November 2012, Richard Honeycutt's published this article exploring how to detect audio amplifiers’s differences in sound and the need for a correct subjective evaluation process of components and systems.
