LS-80 loudspeaker cable
EWA LS-80 is a very surprising step forward over LS-40 - surprising because LS-40 is already a reference quality cable.
LS-80 is bi-conducting LS-40 inside the braided sleeve. There is a little more to it than that, but not very much. Is it the same as bi-wiring LS-40? - No: The fact that two runs are bound closely together compounds what LS-40 already does so well. Sure, there are more conductor cores in each side, but it is the common mode choke effect and mutual magnetic coupling that become much stronger due to proximity, and our unique termination system ensures we maximize this advantage.
With LS-80 music sounds bigger. Larger, more expansive. The scale is truly impressive, even overwhelming; the dynamic potential is sometimes a little intimidating. You will get that sense - a truly grand sense - of scale and presence at much lower volumes, while at higher power you won't even be aware of the volume as the music washes over you. Everything in it's place, each detail real enough to touch. Let the brakes off your music.
The effect of upgrading to EWA LS-80 is subjectively rather like upgrading your amplifier to one of much higher power and quality. It's not about the volume, it's about the control, the scale, the dynamic event, the stereo image; doing all this while being in complete control, without harming the timbre or texture. Music sounds bigger, closer, all around the listener in fact. This is what perfect phase sounds like.
Why should perfect phase matter? Audio devices and loudspeakers change the perceived phase all the time: The issue here is non-linear phase shift, when the phase angle changes as the frequency and/or amplitude changes. This is what is egregious to the ear; phase changes that are relatively static don't cause too much harm - just as well when they may be built into an audio system - it is the non linear shifting during the music that is bad. EWA cables are designed to prevent these shifts.
