Gryphon Essence Stereo Power Amplifier - As Traded
Condition: Used. Very good, minor scuff on front fascia and swirl marks from cleaning (See photos, difficult to photograph)
Includes: Original shipping crate, power cable
SN: 1612424
Warranty: 90 days (3 months)
Overview
With an ultra-wide frequency bandwidth (0.5 Hz – 350 kHz, +0 dB, -3 dB), Gryphon Essence is conservatively rated at 50W into 8ohms, Class A.
The custom-built, shielded, high current toroidal transformer offers dual windings for left and right channel, with symmetrical AC power polarity for the amplifier stages.
The output and driver stage employ separate power supplies for effective isolation. A separate transformer for control and display circuitry isolates them from the signal path.

Generating expert take…
Gryphon Audio Designs emerged from Denmark in 1985, founded by Flemming E. Rasmussen as a passionate offshoot of his distribution company, 2R Marketing. What began as a spare-time project—a compact, dual-mono phono preamplifier known as the Gryphon Head Amp—quickly gained acclaim after debuting at the 1986 Chicago Consumer Electronics Show. Japanese distributors snapped it up, and the audio press hailed it as a "Best Buy," propelling Rasmussen to establish Gryphon as a dedicated entity by the early 1990s, free from import distractions. The brand's name draws from the mythical gryphon, symbolizing the fusion of lion-like power and eagle-like grace in music reproduction.
Gryphon specializes in uncompromising high-end electronics, starting with its legendary class-A phono stages and evolving into high-power amplifiers, preamplifiers, and integrated systems. The company expanded into full-system solutions with the 2002 Cantata stand-mount speakers, followed by flagship models like the massive Poseidon in 2004. Today, its portfolio encompasses speakers, the groundbreaking Apollo turntable—a collaboration with Helmut Brinkmann and Ortofon—and even cables, ensuring every link in the audio chain aligns with Gryphon's neutral, optimized design philosophy.
Positioned firmly at the pinnacle of high-end audio, Gryphon commands respect among discerning audiophiles for its visionary engineering and sonic purity, often setting benchmarks since its inception as one of Europe's earliest true high-end pioneers. Rasmussen's team-driven approach yields products that prioritize musical essence over compromise, attracting buyers who demand reference-level performance in home systems.
