I don’t believe that a specific brand of power cord is supposedly matched best to a specific brand/model of audio device. In my experience, it really comes down to power cord material (metallurgy) and composition/geometry.
I recently made a set of power cords by getting an Audioquest NRG-4 (the best Audioquest cord without the DBS battery). I chopped the ends and put Furutech rhodium connectors on. These power cords excelled! the NRG-4 uses their best PSC+ copper, which is the Audioquest version of OCC. Audioquest is also the only company I found that uses solid core conductors. The NRG-4 uses 4 x 19awg for hot, which makes 13awg. The neutral/ground are 5 x 21awg, which is 14awg.
In all my testing, solid core always wins. Stranded just does not sound right - I found it gives a solid-state digital effect (or lo-fi). I have tested this even with high grade Furutech OCC copper stranded cords.
