My Black Magic arrived earlier this month. Put it on my kef blade 2. These are not easy to drive (properly). Dug it so much I listed & sold my Sanders Magtech to pay for a 2nd amp. Which arrived 2 days ago. Zero regrets.
Ergo: Black Magic running mono. See my system page.
Ergo: ask ACTUAL OWNERS like me what they're like, their service, and oh yeah: they sound killer. happy to chat @silverfoxvtx1800
