Product Description

The eagerly anticipated Gryphon Colosseum is the first new Gryphon component since the Mirage preamplifier, the radical design experiment that laid the cornerstone for an esoteric third tier of Gryphon components. Representing the most comprehensive development project in Gryphon's history, the Colosseum Stereo Power Amplifer will enhance any home audio system.

For ultimate convenience, the Colosseum can be configured to turn on automatically when the preamplifier turns on and to power down following a period with no signal. A software-based user interface permits easy, intuitive access to practical user-controlled features.

Gryphon Audio Designs remains committed to discrete circuitry and 100% Class A bias in the Gryphon Colosseum power amplifier, weighing in at 80 kg.

While the Colosseum takes Gryphon's distinctive styling one step further, our ongoing commitment to uncompromising sound quality is reaffirmed by a wealth of details such as 2 x 160 Watts Pure Class A output power, 48 High-current bipolar output transistors, a 340,000 microFarad power capacitor bank and flat frequency response extending beyond 350 kHz.

The strict dual mono amplifier is suspended between the curved, de-coupled side panels in a unique configuration that provides optimal layout and operating conditions for all components. The dual transformers are isolated and effectively shielded to prevent unwanted interaction with other components.

Unique mechanical design ensures optimal thermal tracking between drivers and output devices. The separate driver section has its own power supply from individual windings on the custom-built toroidal transformers and features its own generous bank of proprietary Gryphon capacitors.

The output section employs Sanken bipolar output devices for extreme reliability in addition to outstanding sonic performance. These transistors deliver momentary peak power of 4,000 Watts per channel without overload. Each of the 48 transistors is bypassed with individual film capacitors.

In the best Gryphon tradition, the Colosseum utilizes a completely independent transformer and power supply for display and control circuits, creating an effective firewall that prevents digital noise generated by these circuits from reaching the amplifier circuits.

Negative feedback is not used and DC coupling is achieved with DC servo circuitry. Internal wiring in the signal path is kept to an absolute minimum. The finest Gryphon Guideline Reference silver cable is used throughout.

The Gryphon Colosseum is fitted with balanced inputs exclusively. Eliminating phono sockets in the signal path ensures the integrity of the sensitive audio signal.

The custom-built Gryphon speaker terminals accept bare wire, spade lugs, banana connectors for a tight, reliable connection.
