I have had The 5 power cable running into a Devialet 220 Pro CI and use Mr. Ghani’s 6:6 speaker cables in biwired configuration to Sonus Faber Olympica IIIs. I am a fan. There is a clarity to what I am hearing which I was getting with the Audioquest Thunder or a Voodoo Thunder power chord. The speaker cables replaced DH Labs Q10 Signature cables. The bass is the first thing you notice but then the effortless nature of the midrange on female vocals, as well as nuanced treble (instead of hot treble) gives an overall ease to the music that I haven’t heard previously.
Science and math indeed.
