TEAC UD-501 Modification

The architecture of the TEAC UD-501 is unique and unseen for a product of this price range and it becomes a totally different beast after our signature mod upgrade.  After the mods, inner details and harmonic resolution, previously submerged by the background noise levels, will emerge.  You will find that every aspect of the sonic reproduction from the DAC improved.  Bass, PRaT, sound staging, natural, accurate tone of human voice and instruments, are improved by leaps and bound.

Overview

  • 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

    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.

We replace the stock voltage regulator powering these oscillators with our Ultima low noise voltage regulator, then changed the critical components to higher grade parts. The analog output circuit is also modified for better sonic. Six stock power supply voltage regulators are changed to our Ultima low noise voltage regulator further reduce the noise at power line for DAC chips and Opamps.
