Musicality and Distortion: A Conversation

Three audio experts discuss the role of distortion levels in what we hear. The debate was caused by an article titled “Amplifier Musicality - A Study of Amplifier Harmonic Distortion Spectrum Analysis” by Jean Hiraga, which originated comments by Jan Didden, Dennis Colin and a subsequent response by Jean Hiraga. The original article appeared in audioXpress March 2004 and the resulting conversation was published in audioXpress October 2005.

Extend the useful life of those precious tubes: use a Tube Amplifier High-Voltage Delay

Tube life can be extended if you delay the application of high voltage until after the heaters have warmed up and current can flow. This little module does just that: depending on the setting of a jumper, it delays the high-voltage for 40 or 60 seconds after the amplifier is switched on. And the module is available as a kit. This article was originally published in audioXpress, February 2014.
