This looks promising for those wanting to try the large gauge wire DIY path;
https://www.rockvilleaudio.com/12-feet-r0g100red/Like Geoff and Wolf I have recently gone back to my solid core cables. Not AQ but Harmonic Technology that uses multiple, thin, OCC copper wire individually insulated with foamed PE. Just ordered some more, which I will use to run tfull 9 awg wires to each of my 8 speaker binding posts. I am seriously thinking of trying the large gauge thing just for fun and the linked Rockville cable at $25/12 feet looks like it could be perfect for the purpose.
