Ultimate Reference Monoblock Amplification | Trimira Audio Specialist
The Gryphon Audio Hyperion Monoblock Power Amplifiers are reference-level pure Class A monoblock amplifiers designed to provide maximum channel separation, current delivery, and loudspeaker control. Handcrafted in Denmark, each amplifier uses a dedicated chassis for a single audio channel, creating a fully independent amplification platform.
Each monoblock incorporates two 1,500 VA toroidal transformers, 40 high-current bipolar output transistors, and a 500,000 µF power reservoir. The pair therefore provides four transformers, 80 output devices, and 1,000,000 µF of total filter capacitance.
With 200 W into 8 Ω, 400 W into 4 Ω, and 800 W into 2 Ω per monoblock, the Hyperion is designed for demanding high-end loudspeakers. Zero global negative feedback, a fully balanced Class A topology, and Gryphon’s Green Bias control complete the amplifier architecture.
Key Features & Acoustic Engineering Highlights
-
Dedicated Monoblock Architecture: Separate chassis and power supplies provide complete left/right channel isolation and maximum stereo separation.
-
Apex-Derived Output Stage: Each monoblock uses 40 high-current bipolar output devices for substantial current delivery.
-
500,000 µF Reservoir per Monoblock: Large power-storage capacity provides significant energy reserves for demanding musical transients.
-
Dual 1,500 VA Transformers per Monoblock: Two dedicated transformers provide substantial independent power reserves for each channel.
-
Zero Global Negative Feedback: Pure Class A circuit architecture operates without global negative feedback.
-
Green Bias Control: Manual Low, Mid, and High bias settings or automatic bias tracking via compatible Gryphon equipment.
-
Ultra-Low Output Impedance: 0.010 Ω output impedance provides strong electrical control over compatible loudspeaker loads.
-
Balanced XLR Pass-Through: Balanced XLR inputs and pass-through outputs support high-end system integration and bi-amplification configurations.
