Esoteric’s Manufactured Clock Module
The “Master Sound Discrete Clock” in the G-05 has been developed by Esoteric in-house, from the selection of the crystal oscillator to the temperature control circuit and its control program to achieve high precision, all completed in a unique discrete circuit. Esoteric’s in-house clock module is dedicated to music reproduction. We have paid close attention to every detail and improved the quality of musical expression by designing our own crystal oscillator circuit, previously packaged as a general-purpose module, into a unique discrete circuit to produce tones closer to our engineers' ideals.
“Esoteric SXT-03” Custom Crystal Oscillator
Crystal clocks generally have a natural timbre, low phase noise and excellent stability when combined with advanced temperature control systems. In addition, as the clock signal is generated by oscillation, there is a strong correlation between the physical properties of the material and the final sound quality achieved. Larger crystals have greater self-oscillation and a greater oscillation margin, even with greater resistance in the circuit, making the oscillation more stable. The G-05 is equipped with the Esoteric SXT-03, a large custom crystal oscillator with ideal electro physical properties. The raw crystal material is slowly grown over a long period of time and then SC-cut (Stress Compensated Cut) with excellent temperature characteristics. We also scrutinize the manufacturing process down to the smallest detail, carefully selecting and using crystals whose center frequency fluctuations are strictly within specifications.
Master Sound TC* – Esoteric's Proprietary Temperature Control Program
Crystal frequency accuracy is affected by temperature. Therefore,
temperature control is the most important factor in maintaining high
clock accuracy. Esoteric's proprietary "Master Sound TC" is a total
temperature control system that maximizes crystal performance. We have
developed not only the hardware but also the control software in-house
to ensure that the Master Sound Discrete Clock delivers the highest
possible performance. In a typical OCXO, crystals are stored in a hot
oven and kept at a constant temperature. However, crystals differ in the
temperature at which they are most stable. In our Master Sound TC
system, the oven temperature is controlled by a program customized for
each crystal to ensure that each crystal is always at the right
temperature for stable performance. The result is an extremely natural
and pure clock output with excellent musicality.

128-Step Multi-Step Controlled Heater to Maintain Uniform Oven Temperature
The heater, which maintains a uniform temperature inside the oven, is
also a concentrated Esoteric specialty. The heaters in ordinary modules
are simply controlled to repeatedly turn on and off in conjunction with
the falling and rising temperatures inside the oven, but in the Master
Sound Discrete Clock, the temperature is finely controlled by a heater
with 128 steps of multi-step control. In addition, by minimizing the
current fluctuations that occur when the heater is turned on and off,
the adverse effects of current fluctuations on the crystal oscillator
circuit are eliminated.
Three Independent Power Supply Units for Superior Musical Performance
OCXO modules are typically configured with a single power supply. In the G-05, however, the power supply section is independent of the oscillator circuit, heater/control circuit, and buffer amplifier, and the optimum voltage is supplied directly to each circuit block to achieve high sound quality.
Esoteric-HCLD Output Buffer Circuit
The G-05 is equipped with the highly acclaimed "Esoteric-HCLD" output buffer amplifier circuit found in the Grandioso C1X preamplifier. It takes advantage of its powerful current transfer capability and 180MHz wide frequency response to deliver pure 10MHz sine wave clock signal to connected digital players.
Equipped with Four 10 MHz Clock Outputs
Four 10 MHz sine wave clock outputs are provided to supply clocks to up to four digital devices.
Custom Designed Coaxial Cables with MIL-standard SMA connectors
Special custom coaxial cables, carefully selected for sound quality, are used for the critical wiring inside the G-05. The connectors are gold-plated SMA connectors that comply with MIL standards. The output connectors are gold-plated BNC connectors with precisely matched impedance = 50Ω to increase transmission reliability and reduce loss.
