Tube Preamp with "pass through" for HT option?

Can any of you suggest a tube preamp with a HT pass through so I can use a tube preamp for 2 channel listening and my Myryad MDP500 G6 for home theater and satellite (with the option for 2 channel too). I am just venturing and gaining knowledge into tube setups so ignore my naivity if it applies. My plan is to continue to use and Anthem MCA II Series 2 Solid State 2-channel amp to power my Dynaudio Contour 1.3 II speakers. The other amp is an Anthem MCA III series 2 which powers the center and 2 surrounds. If a tube amp like this is available without breaking the bank (again!) please suggest and how would be best to hook up? Thanks. Dave
