    • Unwanted disconnection or partially pulling out from the socket.
    • Movements causing harmful “short transients” due to short power interruptions.
    • Vibrations / Resonances that are known to be harmful to sound performance.
  • Mechanically relieves the wall outlet and the power cable connector, especially the contacts, from overloading, bending, breaking when using heavy and inflexible High-End power cables.
  • Protects the contacts against dust and moisture and thereby prevents, or at least slows down their oxidation, and thus ensures the ideal, long-term electrical connection.
  • SE² models are equipped with the best audiophile-grade Furutech rhodium-plated NCF wall outlet and with extended shielding to suppress radiated EMI (Electromagnetic Interference).


Many of today’s High-End audio components claim to reach for perfection…
However, with a power cable connection, “perfectionism” usually ends.
But in fact, everything begins right here:
All components are supplied with essential energy through this connection!
Therefore, this connection must be maintained absolutely securely.
And more than this: Reliably free of vibrations & resonances,
movements causing short transients…
In the real world of High-End Audio, most aftermarket power cords
are usually very heavy and inflexible.
Your standard wall power outlet isn’t intended for such heavy loads.
Consequently, the contacts in the standard wall sockets are very overloaded,
bent, and can even be broken.
This is hardly perfection — nor fully realizing the benefits
of your expensive aftermarket power cable.
