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.

Pure Power In, Pure Power Out

Since it is the function of a power amplifier to modulate the mains current from the wall socket, the presence of even miniscule amounts of noise in the mains voltage can prevent a system from living up to its ultimate potential.

The carefully regulated and filtered power supply of the Gryphon Mephisto removes harmful high-frequency noise and voltage spikes without compromising current capacity. The complete removal of mains noise enhances focus, immediacy, transient crispness and soundstage depth for a more beguiling and engaging listening experience.

Zero Global Negative Feedback

While negative feedback is a widespread means of suppressing measurable static forms of amplifier distortion, copious amounts of feedback have the unfortunate side effect of introducing an over-damped, sterile sound, because the feedback itself leads to a rise in audible, dynamic distortion.

Gryphon Mephisto is designed with zero global negative feedback in order to meet the dynamic demands of the very best analogue and digital source components. The exceptional bandwidth of the Gryphon Mephisto äóñ beyond 350 MHz - is achieved despite the total elimination of feedback.

Mephisto is equipped with effective protection against overheating, DC input offset, short circuit, RF and incorrect voltage supply. Slow-start turn-on circuitry analyzes and confirms the status of the transformer, bridge rectifier, power supply, reservoir capacitors and amplification circuit prior to full power-up and before accepting any input signal.

Because the advanced Mephisto protection circuitry is kept outside the signal path, full protection is achieved at no sacrifice in sound quality.

The Mephisto binding terminals are custom designed, massive, gold-plated connectors which provide secure power transfer with speaker cables of any diamete

Weighing in at a healthy 108 kg and worthy of its origins as a one-of-a-kind design concept to demonstrate exactly what can be done with no constraints or restrictions of a monetary , practical or technical nature, Gryphon Mephisto offers stunning analytical capabilities that cut straight through to the emotional core of recorded music.

Paired with the equally uncompromising Gryphon Pandora preamplifier and connected with advanced Gryphon interconnects and speaker cable, the Gryphon Mephisto will continue to define the state of the audio art for years to come.
