PSU1 Enigma Power Supply

Originally designed for the Accession MC and finding it delivered an audible improvement with the Majestic Pre/DAC, the PSU1 Enigma has since also found favour with many Graham Slee owners.

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 result is greater clarity particularly when using the Accession MC phono stage, in fact it's like getting the improvement the standard issue Accession MC provides, all over again.

PSU1 Enigma is supplied WITH a DC power cord. Please contact us before purchase if you do not need this.

PSU1 Power Supply

The Graham Slee PSU1 Power Supply delivers a significant sonic upgrade over the standard Basic Power Supply. Low noise, 24V DC, and supplied as standard on many higher-tier Graham Slee products.
