I have bartok + diablo 300 and magico A3.
I am using siltech classic anniversary line 770 full loom, xlr, sc and pc.
They’re very neutral, dynamic, organic and balanced cables.
Don’t mix brands for cables, go for one and get all the cables the same brand. The siltech power cords are good enough for this setup.
For the voltage I find 2v works best for me.
For the power, if you can try to put a dedicated line, one for the bartok and one for the diablo.
It makes a huuuuge difference, better than any cable.
