Amp for Shahinian Obelisks?

Hi guys

Anyone recommend amps for my new Obelisks? I heard the Plinius 9200 was ok but wondered if tubes would do it? Like these:

Or high power Mcintosh?
Bryston?
Jungson JA-50 monos?
Krell?

My music is rock and electronic biased with lots of live music etc.

Really appreciate your thoughts!
