The Master Clock Generator takes the musical expression of digital sources one step further.
The G-05 is equipped with the “Master Sound Discrete Clock”, a clock module developed entirely in-house.
The Master Sound Discrete Clock, a completely in-house developed OCXO* clock module, has been designed to enable the combined digital source equipment to take musical expression one step further.
The G-05 Master Clock Generator is now available with this in-house developed module, which will bring out the full musical reproduction potential of the Esoteric K and N series, as well as a wide range of other digital players.
* OCXO = Oven Controlled Crystal Oscillator
The new Esoteric 05 Series
Minimalist and beautiful styling distilled from Esoteric's flagship technology and quality. And the superb sound that transports the owner to a first-class listening experience. This is the core concept of the Esoteric 05 Series, the core of the Esoteric brand.
The 05 Series consists of the brand's iconic K-05XD Super Audio CD player, the N-05XD Network DAC preamplifier, and the S-05 Class A stereo power amplifier, which incorporates the development results of the Grandioso Series. In addition, the G-05 Master Clock Generator, featuring the unique Master Sound Discrete Clock, has been added to the lineup, making it possible to expand an audio system that is even freer and more suitable for the pursuit of sound quality.
- “Master Sound Discrete Clock”, which can make the sound quality of the connected digital player more musical.
- The G-05 can be used with Esoteric K-series, N-series and various other digital players that have a 10MHz clock input.
- The Esoteric SXT-03, a large custom crystal oscillator with ideal electro-physical characteristics.
- Master Sound TC, a unique total temperature control system.
- Multi-stage heater control with 128 steps to maintain a uniform oven temperature.
- Three independent power supplies that directly supply the optimum voltage to each circuit block for high-quality sound.
- Esoteric-HCLD buffer circuit that can output a pure 10MHz sine wave with its powerful current transfer capability.
- Four 10MHz sine wave clock output terminals.

Unique Features
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.
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.
Four 10 MHz sine wave clock outputs are provided to supply clocks to up to four digital devices.
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.
The chassis construction is also specially designed for vibration-sensitive master clocks. The front and side panels are made of heavy-duty, thick-walled aluminum to suppress external vibrations. The Master Sound Discrete Clock module inside the chassis is freely mounted and grounded by its own weight without the use of mounting screws. The isolation feet, machined from steel and supported at three points, use a special mounting method that uses the weight of the chassis to connect to the bottom plate. By eliminating as many screws as possible for mounting the clock module and isolation feet, and by avoiding the stress concentration caused by screwing these vibration-sensitive components together, a natural vibration damping effect can be achieved, resulting in superior sound quality. In addition, the top plate has a semi-floating structure that is not fixed with screws, resulting in an open sound.
