Tube Pre into HT system?

My room has to do double duty for HT for the family and music for me. Are there any tube pre's that integrate easily into a HT system to provide a little tube sound when listening to 2-channel music? FWIW the system:
Proceed PMDT
Proceed AVP
MF NuVista 300
Proceed AMP3
Revel Studios
Revel Voice
Revel S30
