Tube Dac to Tube pre?


I use a Lite Audio tube dac but am thinking about a tube preamp. The preamp has no digital input so would have to go rca from squeezebox duet to the pre if I cannot use the dac.

Would using the dac to tubed pre be doable?
Thanks

Thanks.
Dac and pre have rca so that should cover.
Schubert, you mention "more variables than are wise" and I would appreciate your explanation. Tubes are new to me. Are you saying that having two components with tubes may not match up well?
Thanks for the replies.

I enjoyed a tube dac to a SS preamp to a either a SS or tube amp. Schubert is very right about the additional variables. I like having somethings I can't easily change in my systems.
I have used Tubey dacs with SS amplification, i think it adds the magic of tubes with the benefits of a SS.

Like an hybrid solution.
Scoly1 I have been using a tube output cd player to a tube linestage preamp with a ss amp with very good results. You can also taylor to your likings by tube rolling. Go for it.
