Frankly, there is no technology in speaker wire relative to all the technology in speakers. Spending as much as you have done or plan to do on a minor tweak like speaker wire is not effective especially when said wire is approaching the cost of your speakers / in such a case, a modest speaker wire coupled with a speaker upgrade would bring a lot more benefit.
apologies if this does not answer your question - just felt compelled to warn you of diminishing returns. As significantly higher cost bits of wire are still fundamentally bits of wire. A better speaker with higher cost drivers and good design and construction presents a huge opportunity for improvement.
