Hybrid Balanced Tube Preamp?

Hi Guys,
I am running a hybrid power amplifier which has two tube complement in the input section (rest is a solid state but class A) - i want to partner this amplifier a equally good "Hybrid Tube Preamp" which is Fully/Truly balanced, and would like "minimal" tubes..most shortlisted now seems unattainable because these units carry 4 or more tubes (Veloce,cary SLP) and the other brands have tubes in the output stage and mostly unbalanced (redwine audio,herron etc) - do you guys know of any other brands? does it make sense for me run a SS preamp like Hegel etc? i guess it defeats the purpose of then again having tubes in the power section!
