As we strive to push back the boundaries of what is possible in home audio, Gryphon Audio Designs occasionally builds highly experimental testbed prototypes. We create these no holds barred components for our own edification as tools in the development and refinement of real-world products. These rarefied, strictly non-commercial laboratory instruments serve as an absolute reference for the current state of the art. They are take no prisoners exploratory projects, built with scant regard for cost, just as size, weight, appearance, transportability and spousal approval are wholly irrelevant. The latest of these experiments, designed with no thought for the marketplace and no intention of being offered for sale have been dubbed the Gryphon Pandora preamplifier and the Gryphon Mephisto power amplifier.
