In general you’d expect moving up within a company’s product line should yield improvements, especially if in addition to gauge you get other improvements in things like quality of the conductors, geometry, connectors, dielectric, etc. So there are several variables at play here in addition to the gauge of the cable.
Will increasing speaker cable AWG make a difference in sound quality?
Increasing speaker cable size (for example w/AQ the cable sizes move up in size from 15AWG to 10AWG) improve sound quality?
