Surround Receiver For Zu Druid ?

Hi, first post so be gentle :)

I've got a full surroundsystem with the Zu Druids and I was hoping someone here got any idea what would be a good pre/pro or receiver for this system?

This is obviously a compromise in the music department, and a expensive 2 channel tube amp wouldn't be practical enough for me, but I would like the receiver to sound good in stereo, what brands do people use with Zu? or Is It just me who got the Druids for a 5.1 system?
