Mephisto Stereo

Living up to its heritage as an evaluation tool, the Gryphon Mephisto is revealing with unrivalled surgical precision, yet remains inherently musical and true to the heart and soul of the performance. Without ever losing sight of the subtlest nuances and micro-details, Mephisto maintains a firm grip on coherence, timbre and the overall musical event.

As a consequence of this groundswell of encouragement, Gryphon founder and CEO Flemming E. Rasmussen decided that it would be an appropriate celebration of the twentieth anniversary of the very first Gryphon amplifier to offer our bench tools in a strictly limited edition to the select circle of individuals who share his unwavering obsession with the exploration of the farthest boundaries of music reproduction with no concessions to cost, size, weight and fashion.

The bold lines of the custom made Mephisto heatsink profiles and distinctive sheen of the brushed aluminium housing provide a visual signal of exactly what to expect when the Mephisto is powered up in collaboration with the few audio components in the world that are worthy of its company.

DYNAMIC INTEGRITY

As befits a product of its unique pedigree, the Gryphon Mephisto power amplifier stands in a class all its own when it comes to the crucial area of maintaining dynamic integrity, regardless of load conditions.

Mephisto is built to meet the challenge of the most advanced contemporary loudspeakers which typically present vicious reactive loads while drawing huge amounts of current. The dual mono Mephisto is capable of massive peak current swings and, equally vital, can do so into very low impedances without losing its cool.

Because Mephisto’s perfectly linear output impedance preserves the integrity of the audio signal unconditionally, regardless of frequency or signal level, the amplifier’s exceptional load tolerance makes it an ideal partner for the very finest loudspeakers.

In keeping with long-standing Gryphon tradition, the quality of sound reproduced by Gryphon Mephisto is completely level-independent. It is a huge amplifier capable of delivering its best at any volume setting, from background levels to full throttle.

To generate and control such pure power, each Mephisto channel is fitted with separate AC power inputs and individual custom designed Holmgren transformers with generous filtering capacity well-suited to the delivery of high pulse current. The fully regulated gain stage power supply ensures long-term reliability and safety.
