Harmonic Technology Recta series ,any experience with these?

Anybody auditioned these or have them currently?I used to have their ics and speaker cables (Truthlink and Pro 9) in a different system long ago and really liked them.The Recta looks interesting and I imagine would have a different 'flavor' than the warmish sound that I experienced before.I'm in need of cabling that leans toward the cooler side.
All of my components are tubed so warm sweet cables are too much of a good thing.Yesterday I swapped in a pair of Clear Day(single,not the double shotgun) speaker cables for the Black Cat Coppertones which was an obvious step in the right direction.
