Audio Envy sent us some demo ICs and speaker cable to check out. Surprised us actually. To start they are Harmonic Kings. They beat out the Belden Iconoclast, Gronenberg and Tara which in our opinion are VG cables.
A new Kid on the block that I believe got it right. One size does not fit all as we know. If one is looking to color their system there are other cable options. If one wishes to add nothing to signal these are them.
They also make guitar cables. My Son said he can hear more harmonics and has better tone. He uses a vintage tubed Ampeg.
