Nonoise, have you listened to any of the Omega Mikro ics (Mk VI and Mk VII in my case) or the planer speaker cables in your rig? I find them a quantum improvement over the Mapleshade Excaliber ics or double helix speaker cables. As good as the Analog VI ic is the Analog VII just gives you more, spacial resolution, timbre accuracy and coherence. Goodness knows what you get as you get into the directional cables with the bias boxes, haven't heard them, yet! I've never remotely experienced this level of improvement from any other cable including Stereovox, Vahalla, Harmonic Technology, Audience, Cardas, MIT. I would venture a guess that too much of this may not be the best solution in an otherwise transparent revealing system, use judiciously.
