Gryphon Audio Designs to Launch Zena Preamplifier in Manhattan

The following is a press release issued by Gryphon Audio Designs.

October 16, 2018 - Gryphon Audio Designs are proud to launch their new Zena preamplifier in Manhattan on Thursday 18 Oct. @ 7:00pm.  Your hosts will be Joe Cali and Philip O’Hanlon (On A Higher Note) playing a wonderful collection of hand curated music.

The  Gryphon Zena is a  true dual mono preamplifier harvests the fruit of significant advances made in the evolution of the state of the art Gryphon Mirage.

The Zena preamp is based on an exclusive, fully discrete, DC-coupled Class A topology with zero global negative feedback and extended 1 MHz frequency bandwidth, all contributing to high slew rates, extreme transient fidelity and zero treble phase shift for proper focus with fine ambient micro-detail.

The Gryphon Zena replaces the Athena ball-bearing volume wheel with touch-sensitive up/down buttons to create a volume attenuator consisting of 43 individual steps in 2 dB increments, with no more than two resistors in the volume control signal path at any given time.

Among the numerous component upgrades of the Zena is an ultra-precise array of SMD metal-foil resistors and hermetically sealed, gold-plated, ultra-low capacitance Pickering reed relays.

Equally crucial, the Zena volume attenuator is fully balanced, with no conversion of the signal from the XLR inputs to single-ended prior to attenuation. This simplification of the Zena signal path represents a major step forward in sound quality.

The Zena employs shunt regulators in the voltage supplies to the active circuits of the volume attenuator, in order to ensure a DC supply with ultra-low output impedance across a wide frequency band and optimal noise suppression.
