You overlooked the best value of the bunch , the Wireworld Eclipse
they are not like everybody else , many for starters don’t all use Copper connectors which is very important for sonics as well as conductivity ,many use gold over bright sounding Brsss. WWorld use Silver over high grade copper. The wire
is 6-9s pure Occ Copper in a straight Litz wire to avoid eddy currents ,
the comdilex dielectric is even better then Teflon and holds their patent.
the speaker cable can be ordered standard or biwire for it is very robust awg 9 gauge , the interconnects similar geometric and right in your budget .
