GRYPHON MEPHISTO STEREO POWER AMPLIFIER
This unit is SOLD!
Trade-in Mephisto power amplifier in excellent condition. 1-year-old unit weight a hefty 110kg- Pure class A.
Extreme Attention to Detail
Each printed circuit board in the Gryphon Mephisto is designed to facilitate accurate assembly and precision mounting to set a new standard for mechanical and electrical stability.
Ideal, safe operating conditions for all transistors in all amplifier stages maintain consistent performance, regardless of temperature or signal level variations.
Only the finest components are employed for optimal electrical and audio characteristics, including Takman resistors from Japan, Class A dual J-FET transistors in the input buffer for speed and clarity, and a balanced differential input circuit based on a single carefully selected dual bipolar junction transistor. The voltage amplification stage incorporates high-speed Zetex surface mount transistors with minimal capacitance and high DC gain (Hfe). The output stage employs high-speed Toshiba pre-driver transistors.
A fully symmetrical, regulated low noise voltage supply has been used for all voltage amplification sections. Eight 56,000 microFarad capacitors with low ESR (Equivalent Series Resistance) for a total capacity of 448,000 microFarad/100V smoothes the voltage to the output supply.
Static shielding isolates primary and secondary windings in the massive dual Holmgren transformers designed and built especially for the Gryphon Mephisto.
By eliminating output relays, Gryphon Mephisto achieves an extraordinary low output impedance. But most importantly, because output relays that can handle huge constant currents tend to have poor low to moderate signal transfer characteristics, the best relay is simply no relay.
As always with Gryphon, what is left out is just as critical as what goes in.

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.
Gryphon Mephisto Pure Power In, Pure Power Out
Since a power amplifier modulates the mains current from the wall socket, the presence of even minuscule 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. Removing the main noise enhances focus, immediacy, transient crispness and soundstage depth for a more beguiling and engaging listening experience.
