Amp Options - Infinity Kappa 9s

Kappa 9s have a min impedance of about 1 ohm.  This is one of the most notoriously difficult speakers of all time to drive.  I had the first edition Kappa 8s which were bad enough at 1.7 ohms.  I blew a lot of fuses. These are worse.  That said, they are actually extremely efficient and you don't need a lot of topline power.  50w into 8 ohms that will double to 1 ohm is far better than 1000w into 8 ohms if it is not stable at 1 ohm.  

Whatever amp you choose needs to be stable to 1 ohm and these speakers are forward so a warmer tonal profile is important.  For new you could look at any of Naim's power amps.  AGD is surprisingly capable at low impedances.  The Tempo is a good choice.  I use it with 2.4ohm Vivid Kayas and it sounds great.  

Can't speak about most of the the other options here.  

Cheers all. Australia poses some challenges in access to a lot. It’s a bit of wait and see what options come up. 
 

I was recommended an ME850 as being able to drive them well. I’ve copied the link to specs below. Could I ask you guys to take a look and give me your thoughts? I will likely upgrade this when other options come up but just looking for something to get me by. It’s supposed to have strong current and doubles output down to 2ohm and below.

I would look around for a used McCormack DNA 500 for the Kappas.
