EWA IC-25 RCA Interconnect cable

EWA IC-25 RCA interconnect cable: a significant advancement in signal cabling and a testament to EWA's extensive expertise. Meticulously designed by Colin Wonfor and hand-crafted with the utmost attention to detail, EWA IC-25 is a state-of-the-art connection that prioritizes signal integrity and seeks to effectively mitigates electrical and RFI noise through a proprietary inbuilt common mode choke. The cable convincingly resists electrical noise, and exhibits exemplary phase behaviour.



As with all EWA products, the IC-25 is meticulously handcrafted in the UK upon order placement. We offer a 30-day evaluation period, allowing you to experience and assess your new EWA cable in the context of your own audio system. If, for any reason, the product does not meet your expectations, it can be returned for a full refund, excluding shipping costs. However, we are confident that you will find the performance of the EWA IC-25 interconnect cables truly exceptional.

  • EWA IC-25 RCA analogue interconnect

    (Tested with AIM LCR Databridge 401 at 1M, 1KHz, 21C)


    • Signal capacitance: 3.8p


    • Signal resistance: 2.1mΩ


    • Signal inductance: 1.3µH


    • Return resistance: 2.1mΩ


    • Return inductance: 1.5µH



    OEM RCA plugs, solder termination. Purified anaerobic copper base with high quality gold plate on nickel layer. Locking (twist) barrel with split flange.


    Coaxial design with dual shields - Electro Magnetic and Radio Frequency Interference (EM & RFI), working in tandem. Excellent conductors are used to maximise the potential of this design.


    A previous test of IC-25 (1M unbalanced, with no termination) involved measuring the cable wrapped around a source of intense radiated electrical noise. In comparison with a high end and even higher priced competitor product (which Colin also deigned), IC-25 was an extraordinary -30dB over the competitor in terms of noise suppression.
