The design of the G-0Rb is fully optimized around its Rubidium (“Rb”) clock oscillator core. Because the G-0Rb does not have a crystal controlled oscillator, voltage variations and other external influences do not affect the accuracy of this master clock generator. The Rubidium oscillator is mounted in its own temperature-controlled and electrically-isolated oven, making the G-0Rb the most stable oscillator in the audio-video market.

Custom-designed ESOTERIC SMB coaxial cable (incorporating high purity 6N copper wire), is used for clock signal connections from the Rb unit to other circuits. This design helps your audio system achieve advanced three-dimensional imaging and exceptional acoustical transparency.

The G-0Rb is finely-tuned by incorporating many acoustically selected, high quality parts. The incoming electrical power path is connected through a high-quality rhodium-plated power inlet plug, and directly to the main power supply without passing through any stand-by circuit. This design provides higher signal path purity. The power supply uses specially selected capacitors for rich power stability. High purity 6N copper wire is used between the power supply unit and Rb unit circuits. (6N copper provides a conductive purity level of 99.99997%).

The flagship master clock generator G-0Rb provides sophisticated high-end reproduction capability and musical expression by creating the highest quality clock signal that Esoteric has ever achieved!
