Finding the right tube preamp (input values) for Mccormack DNA

Forgive me but how do I determine the input sensitivity on any particular tube preamp? 

I have tried to figure it out some manufactures are easy and label it but some have a lot of values and with my limited knowledge of values and current specs I find it hard to figure out which is a good match.

I have a Mccormack DNA-1 Deluxe and am looking to add a tube pre. I have seen the likes of Audible Illusions, Conrad Johnson, BAT, and others who are good matches but I would like to possibly see about modern gear for a good match. Like Jolida, Rogue and Odyssey to name a few. 

What are the specs I am looking for to see if they are a good match? I have read the Mccormack has input value of 10v.

Thanks,

You want a preamp with plenty of overhead, so at normal volumes it makes no distortion. That might be that 10Volt figure, although IMO that's a little low.
Since you have NHTs the gain might be handy although most tube line sections won't have 28 dB- 15dB is more comon. The input impedance of your amp is 100K (single-ended) and so nearly any tube preamp can drive it.
