My experience with the Pangea have been generally positive for their price points. I have both an AC14SE and an AC9SE.
The AC9SE really added bass extension and a nice top end detail as well. But ultimately the bass is noticeably more loose than that from better cords and the mids and highs, although better than a stock cord, were slightly diffuse compared to higher quality cords.
The large gauge of the AC9SE appears responsible for the increased bass response over standard cords, but I do NOT agree with the generalization that 'cords below a given gauge' don't make much difference.
Much more important than size/gauge is a cord's materials, construction, geometry/design, conductor type, metal purity, dielectrics, and plugs/connectors.
