Sonic Craft OPUS R3 Reference 3 preamplifier


Solid State designed by broadband high-definition sound quality with Full Balanced implementation.
Sound quality oriented discrete composition and 100% precision resistor parts. To further improve the volume module new SOV (Smart Opto-conductive Volume) was implemented. Internal secondary DC power supply is designed to supply constant current output MOSFET mode for greater power supply. Full-featured digital control method for your convenience of remote control and manual control. PCB with thorough Dual Monaural configuration for stability and low noise performance.
