The P6 Pro line-out is balanced 4.4mm and the Formula S is a single-ended circuit design with SE inputs. I would suggest you pair it with a 2V capable SE line-in. As for power, the Formula S has enough for both in high gain mode.

Do you think the SE line out from the P6Pro into the Formula S would be sufficient to drive the Abyss Diana , or even Susvara?
