DDHiFi TC09S USB-C to USB-C cable (10 cm)

But to my surprise, and confirmed in numerous blind tests, I found this TC09S usb-c OTG cable to offer an improvement in soundstage expansion in comparison to other cables, having a more holographic soundstage with a sound spreading wider left/right.  I tested and compared TC09S cable against stock cables of RU6, S2, W2, and UA5, and found soundstage improvement in every case.  I even tested and compared TC09S against other aftermarket cables, including DDhifi own TC05 and another one from OE Audio, and still found TC09S to have a wider and more holographic soundstage.  I don’t know how to explain this, but I can hear it.  And also, TC09S has the advantage of being bi-directional while TC05 is unidirectional cable.
