Graham Slee Enigma-PSU1 Micro-Signal Power Supply

ENIGMA PSU1 POWER SUPPLY

Originally designed for the Accession MC, and finding it brought an audible  improvement in other components, we are currently making it available as a purchase option with these products.

Perhaps stating the obvious, but what you hear from any amplifier or preamp is because current flows from a power supply and then back to it. Basic understanding sees that It leaves by one terminal and returns to another.

Thanks to Kirchhoff's scientific current laws and the law of conservation of energy we can see current leaves from its origin somewhere in the power supply and has to get back to that origin. Signal current, no matter how well it is treated by the phono stage, must negotiate the inner workings of the power supply. Knowing that origin and how it gets back to it is crucial in understanding how best the micro-signal current returns to its origin with the least possible disturbance.

The Enigma solution was to lower the dissipation factor, improving dielectric absorption (similar to PTFE and polypropylene) for greater frequency stability such that all frequencies of signal current are treated more equally. And additionally: fine tuning its Kelvin paths and giving it a new DC cord and lockable outlet—the noticeable results are greater clarity and solidity of the sound.
