Wow, Grant. You've had more power play than Gordon Gecko in his heyday.
Of those I have tried in our system, I found similar results. The Purist Dominus was the warmest, and the most musical-sounding of them all. The Poiema!!! was the most neutral. Their IC's as well. The Z-Squared are also quite neutral. Great performance, well beyond its pricepoint, IMO.
The darkest (sort of choked, actually) were the Audience cords.
Great thread. A valuable discussion for people cable searching to get some bearings on the sonic spectrum. Naturally, results vary from one system/set of ears to the next. But as we all know, my ears are directly over the earth's axis of auditory neutrality. There, I said it. :-)
