I have several Farad's powering my system so ended testing several different cables in the pursuit of higher audiophile neurosis
I tried the following:
Stock Farad 4x26awg stranded copper in PE with starquad
Level 2 Silver from Farad 4x(26awgx2) solid silver with starquad
Ghent Audio 2x16awg Neotech
DIY 2x16awg Mundorf silver/gold $$$$
DIY 4x18awg stranded 6N OCC copper in foamed teflon(VH Audio) with starquad twist
DIY 4x18awg solid 6N OCC copper in foamed teflon(VH Audio) with starquad twist
DIY 4x18awg 5N solid silver in teflon tubes with starquad twist
The best sounding of the group was the DIY 4x18awg 5N solid silver in teflon air tubes with starquad twist. It provided the blackest background, the most transparency and detail, better bass output and extension, and the largest sound stage. It was a significant improvement over the Level 2 Silver which sounded thin in comparson. The 16awg Mundorf silver/gold had a full and smooth sound but lacked detail and transparency vs the DIY solid silver.
There is a DIY thread on building your own starquad DC cable on Audiophilestyle which motivated me to build and try the different versions.
Upgrading the AC and DC power cords and the fuse has definitely elevated the performance of the Super3 to another level.
