Overview
Fully balanced, pure class-a, fully discrete circuit with zero negative feedback and ultrawide frequency bandwidth. Designed as a no-compromise line-level preamplifier, Sonata has the distinction of being Gryphon's first remote controlled preamp.
With output limiting, memory-stored default volume levels and channel balancing for each input.
Infinite channel separation and no interchannel crosstalk, thanks to the strict dual mono configuration, filtered outboard power supplies for each channel and separate custom-built C-core transformers.
Unused inputs are isolated, thanks to gold-plated input selector relays that break the
ground connection of components not in use.
Even the display is physically isolated outside the preamplifier chassis.
