BAT vk-3ix and Parasound Halo A21 match?

I've have purchased used on Audiogon a BAT vk-3ix preamp. I bought it becausec it was a good deal and figured I could sell it if I need to. Thing is I' don't know a whole bunch about tube gear and my concern is the impedance match of the BAT and the HAlo 21. I've read that you want an input impedance of 100k on the amp. However the Halo is only 66k balanced. Can anyone shed any light on this combo? I have not yet received the preamp.
