Analogue Interconnect Hi-Fi
Our multi test winner! A reinforcement of even the finest details is the goal of all cable design. A traditional cable can, however, not achieve that quality, due to the construction. A good interconnect must have low capacitance and low skin-effect.
The skin-effect has a dynamic and noticeable influence because an audio signal is nothing but variations of frequencies and sound levels. If we were to transfer only one stable frequency the skin-effect would not be any problem. The frequencies push the signal differently far out from the centre of the conductor. High frequencies travel on the surface whereas low frequencies travel inside the conductor.
Thus, the higher the frequency, the higher the resistance.
In order to minimize the skin-effect the EFF-I is designed in accordance with Equalized Frequency Flow (EFF) Technique. It is based on tube shaped conductors with a wall thickness of 0.20mm, which is well below the smallest skin depth within the Audio range. This allows the same resistance for all frequencies. The result is a transparent and exact reinforcement with clear room definition.

EFF-I One of SUPRA´s most awarded products, not without good reason...

  • International Delivery

    Custom Cable will use Royal Mail International Airmail worldwide for all items less than 2.0kgs. Items more than 2.0kgs can be sent using Parcel Force Worldwide, UPS or DHL. When processing your order we select which courier will get the order to you the fastest. If you wish to specify which courier to use then please let us know is the "Notes" section when checking out. For countries outside of the EU you may be required to pay state taxes or import duties. Unfortunately we are unable to cover these costs, so please be aware that you may be required to pay these.

    For countries inside the EU delivery times are estimated between 3-7 working days and slightly longer for all countries outside of the EU.

    Customers in certain countries are also able to choose Royal Mail International Airsure.  Airsure® is generally a day faster than standard Airmail and can be tracked online. Which means the aim is:

    • 2 working days after posting to Western Europe
    • 4 working days after posting to Eastern Europe and postal subsidiaries (Islands and Principalities)
    • 6 working days after posting to the rest of the world

    The above standards are monitored by the independent and impartial International Post Corporation to ensure reliable and consistent delivery, which is why Airsure® is only available to selected countries.

    Please note that Airsure® is an upmarket mail, not a courier service. This means we cannot provide a guaranteed or certain delivery time, nor can we offer compensation for delays or missing Track & Trace information. 

    Prices for International Delivery are available at checkout and are specific for the delivery destination, please see here after adding your product to your cart.
