One of the most difficult tasks we have undertaken has been to extend the capabilities of the Obelisk PRE, which was designed to perform beautifully as a self-contained unit. However, the Obelisk PX dedicated outboard power supply manages to surpass even our highest expectations.
The PX is based on a sophisticated fully-regulated, double-filtered circuit topology, which eliminates interference caused by the mains supply, providing the cleanest possible current to the PRE. It features very high grade components such as a Noratel mains transformer and four 10.000µF Mundorf capacitors custom made to Heed's own specifications. This results in extremely low noise, low inner impedance and negligible distortion performance.
Although the PX is primarily designed to partner with the Obelisk PRE, it can also be paired to enhance the performance of our Quasar phono stage, Dactilus DAC, Luna II preamp, etc.
