FWIW...I run a biwire setup with the top end being AC MI-2's & the bottom braided Cat5...both are high capacitance/low inductance cables. Amp is a McCormack DNA-1. No zobels...no issues. I'll be switching out the Cat 5 cables in favor of a second set of AC MI-2's..don't plan on adding zobels. I don't think the capacitance will be much different between the Cat5's & the MI-2s...actually it'll probably be a bit less.
I have no issues with zobels & would use them if they were needed. When I asked Steve McCormack about the need for zobels in the DNA1 he said, "Hmmm...not sure if you'll need them. Try the cables & if you need zobels you'll know right away as the you'll hear a squeal." I installed the cables & very gently fired things up...no issues & that was a year ago.
