SUT-1M Step-up Transformer

The MK Analogue SUT-1M builds on the development of the SUT-1L – and transfers its impressive virtues to the transmission ratios 1 : 5 and 1 : 10. Clear the stage for Denon, EMT, Audio Technica, Shelter, Clearaudio, Dynavector, Benz Micro and other fantastic cartridges with medium and higher impedances.

This is how the SUT-1M ‘sounds’ in the phono chain

Our SUT-1M simply disappears. It gives free rein to the music and the characteristics of the pickup. The sound is natural, clear, tidy, direct, and supremely confident – exactly what the pickup manufacturer had in mind. The music flows, and the listener enjoys.

The SUT-1M’s design is utterly uncompromising in terms of:

Frequency Response

Phase Linearity

Dynamic Behaviour

Signal-to-Noise Ratio

‘Hum Sensitivity’

Signal Routing

‘Perfect’ Shielding

The transformer is shielded against electromagnetic interference, but also against resonance and direct sound. So it is like a pillar, providing stability to the whole chain:

  • MU metal encapsulation for the actual transformer;
  • Brass body lined with bitumen mats surrounding the MU-metal capsule;
  • Aluminium housing lined with bitumen mats;
  • Sandwich construction: connection of the base plate with an additional stainless steel plate;
  • Sorbothane feet for decoupling from the ground.

The result: absolute serenity of the SUT-1M

Interference and noise, vibrations and microphony are no longer an issue. This gives free rein to the music signal. Furthermore, the transformer can be placed everywhere. No hum or other interference will disturb your musical experience.

‘Direct’ Premium Wiring

As for the SUT-1L, the SUT-1M offers two transformer stages: 14 dB and 20 dB voltage boost – two separate inputs are used, the signal lines are directly connected – without switch. And the number of connection points is reduced by 70 %.

We use specially manufactured and individually twisted strands as well as self-sufficient, individually shielded signal conductors with capacity reduced by 60 %.

The result: more options without compromise

The SUT-1M offers flexibility in terms of amplification and adjustment of the terminating impedance while simultaneously reducing contact and problem points (switching stages).

Fully Balanced

The pickup signal is inherently balanced, and this signal is much less susceptible to interference than an unbalanced one.

The result: come closer.

The SUT-1M ensures ‘pure’ signal transmission, placing you closer to music and the experience of pickup characteristics.
