GRAHAM SLEE Enigma power supply

Originally designed for the Graham Slee Accession MC phono preamplifier, it has since won over owners of the manufacturer's other phono preamplifiers.

Tests of the Enigma power supply with the Accession M and the Reflex M revealed the same improvements, as did tests with the Elevator EXP amplifier.

The PSU-1 Enigma is therefore now offered as an option, but also as an upgrade for all phono preamplifiers from the British manufacturer.

FAQ: Everything you need to know before buying the Graham Slee Enigma power supply

Which units is the Enigma power supply compatible with?

It was first developed for the Accession MC phono preamp, then successfully tested with the Accession M, the Reflex M and the Elevator EXP. Graham Slee now offers it as an upgrade for all of its phono preamplifiers.

What does it bring compared with a standard power supply?

The PSU-1 Enigma uses capacitors selected to very precise criteria, which filter out "microscopic" current noise. It also comes with a dedicated DC power cable that outperforms the one supplied with the standard PSU 1 power supply.

Like all of the brand's electronics, it is made in the UK by Graham Slee.
