  • EWA LS-20 Loudspeaker Cable


    Colin Wonfor designed the EWA cable system from scratch, rather than simply purchase off the reel wire from wholesalers to be re-packaged and marketed. His design goals include (but are not limited to) eliminating common mode noise on the cable, suppressing all phase distortion, and preventing ringing at any frequency. To achieve this he utilized raw wires not usually found in audio cable, and many of the dielectric and insulation materials are his own design and composition. The details of the geometry in the EWA cable system is also quite unique.


    LS-20 is twinned LS-5 within a webbed sleeve. As with LS-5, you will notice the excellent stereo imaging abilities within the widest of soundstages, stable at all frequencies and volumes. This is in part due to exemplary behavior regarding signal phase.


    Due to having twice the conductor material as LS-5 it has excellent bass attack and depth. The bass depth is noticeable only on program material that requires it; otherwise LS-20 performs just as LS-5 and shares the same balance and neutrality. However, when used with larger loudspeakers the bass speed and extension becomes apparent, which integrates seamlessly into an expansive mid-range.
