The Problem

The entire signal path from preamplifier input to speaker drivers contains conductive parts that can be magnetized. Connectors, component pins and even circuit board copper traces may contain nickel or steel. In addition to being poor conductors, these materials may be magnetized by DC current.
Most electronic devices have constant DC leakage, ranging from negligible to considerable, depending on the design. Many preamps and power amps generate a DC pulse when switched on, before stabilizing. This is particularly true of tube equipment. It has also been suggested that even the copper in cables contains oxides that may be magnetized.
The application of DC current is precisely the technique employed in the manufacture of magnets. High end connector manufacturers and others are very much aware of this and subjective listening tests have often pinpointed the degrading sonic effects of nickel. We would estimate that 95% of all gold-plated connectors have a nickel base beneath the gold plating.
When an audio signal passes through a magnetic field, it is prone to magnetically induced distortion (MID) that manifests itself as a “whiteness”, a lack of inter-transient silence and reduced soundstage depth.

The Solution

Those of you old enough to remember the venerable phono cartridge will also recall the indisputable benefits of frequent use of a cartridge demagnetizer. The Gryphon Exorcist applies the same principle to the entire audio system at line-level. (Do NOT use it on your cartridge or preamplifier MC/MM phono input. For cartridge demagnetization, contact your authorized Gryphon dealer to audition the Gryphon Black Exorcist.)
