Tube integrateds with by pass

Are there any tube integrateds with by passes so that I would be able to hook up surround sound receiver?
Check out the Cayins. My A100T has one.
Musical Fidelity has one, but forget which model it is.

Plinius also I believe.
I have a Plinius 9200, but is is solid state.
The Primaluna Dialogue series has ht bypass. They are nice integrateds too.
