Your description of the Maestro sounds very sophisticated. I don't see it in their present offerings. Steve has told me that they no longer use individually coated wires due to centering difficulty, expense, etc. Their present core technology is to compress the bare copper wires to maximize and unify contact, then insulating those groupings and applying their various cable geometries. My StraightWire is way down the line at Octave which utilizes their core compression technology, their insulation mix, geometry, etc. He characterized the Octave II (now III) as most of their available performance before climbing the cost ladder of 'designer sound'.
I don't remember which SW cable we had at Thiel when I left. I do know that the music room was outfitted with the Kimber Black Pearl when I auditioned the 3.7 vs nearly finalized 2.7 in 2012. Those cables are astounding - at $5 figures.
