Eastern Electric MiniMax DAC mods

Our modification improves the performance drastically of Minimax Supreme / MiniMax Plus / MiniMax DAC. We focus on reducing the jitter levels of the DAC, and reducing the digital and analog background noise levels. After the modification, inner details and harmonic resolution, previously submerged by the background noise levels, will emerge.

Overview

  • Ultima FEMTO Clock

    Details

    Ultima FEMTO Clock

    Currently in its 5th generation, our Ultima FEMTO clock now uses Crystek oscillators which are certified to be less than 82 femto seconds in jitter (in some cases and models, less than 50 femto seconds jitter). 

    The DC power supply powering the oscillator is also extremely important to the overall performance of an audio clock.  We implemented a 2-stage design using our Ultima DC voltage regulator circuit, with high quality components, to ensure that the oscillator works in a noise-free environment. For the very best performance we use a silver plated, military grade 50-ohms clock digital signal hook-up cable for our installation.  A low jitter, low noise clock will ensure less DAC timing conversion errors, reducing distortion and lowering the noise floor.  This will bring forth more low level signals and details.  The sound will be much more analog in its feel and texture. 

    Note that we will only allow installation in our workshop in Singapore and the clock is not for kit / general sales.  Our clock is only used for our own modifications.

  • Ultima Voltage Regulator

    Details

    Ultima Voltage Regulator

    Currently in its 4th generation, our Ultima voltage regulator is the finest of its kind in the market.  Using high quality industrial grade components, the regulator’s control element and its voltage reference is powered by its own low noise voltage output.

    With an optimised discrete design , it provides ultimate low noise, high speed DC power performance to your electrical components.

    The use of our Ultima voltage regulators in place of standard regulators will enable fine, low level musical details, previously hidden and distorted by background noise and slow regulation speed, to emerge. The music will be less harsh sounding, with much more details than before. The sound will be much more analog and natural, with instruments gaining their true tone and timbre.

    Note that we will only allow installation of our modules and regulators in our workshop in Singapore and the regulators are not for kit / general sales.  Our regulators are only used for our own modifications. 

  • Good Quality Component

    Details

    Good Quality Component

    For our modifications and upgrade modules, we ensure that very high quality electronic components are used.

    Our modifications philosophy and methodology has always been based on the systematic and natural reduction of noise within your equipment, so that the true potential of your equipment can be realised.  We do not believe in adding more colours to change the sound of your equipment.  The initial “WOW” factor will be there, but ultimately it will fade and leaves you unsatisfied.  You will always be looking for the next component to colour and compensate for the unnatural sound with such a vicious cycle approach. 

    As such, the choice of our components is based on a neutral sound that fit our philosophy and methodology.  These are components that are tested and proven in our hundreds of modifications done.  They are extremely high quality, industrial grade components that will last for a long time.  The sum of their effects will be many more than singular, highly coloured components.

Change the simple oscillator circuit that is used for the ESS9018 Sabre DAC with our Ultima FEMTO low jitter clock (Crystek oscillator) then replaced the critical components to better specifications and higher grade parts. Use our Ultima low noise voltage regulators to power the critical analog circuits and Sabre 9018. To improve both the tube and solid stage audio outputs, a pair of dual opamps will be changed to the Burson discrete Opamps. Original Circuit will be enhanced.
