I have been using ClearDay cables for more than a year now. They have been a great match in my system. I think, in my system, they have provided the "drive" that was missing with the previous cables. Does that mean, they deliver more current to the speakers? I don't know that. They do not sound harsh in my system. In fact I think they bring out the details in the mid-bass that was previously missing in my system. This was especially important for some older 50-60s recordings that I have on cassette tapes.
Yes, the ICs and speaker cables from ClearDay are directional.
