Tube Pre for Klipschorn

What tube preamp match well with Klipschorns; or should I be going the other way and use a SS pre and tube power amp(s)? If so, what tube power amp is a good match with the khorns (Quicksilver horn amps?). I trying to get rid of as much noise as possible. I'm currently using a Quicksilver fullfunction tube preamp, but it a little too noisy and I'm using a Citation XX SS poweramp.

Thanks
