Sanders 10c/d + Magtech + tube preamp


Hi everyone,
I am considering to buy a full system from Roger, but I thought about using a tube preamp instead of sanders' preamp. Anyone has an experience with a combination of the 10c/d speakers + Magtech with tube preamp? Do you have any recommendations?

Lmomo, I am not a dealer but I am in New York. I am on Long Island. You are welcomed to come visit for an audition if you wish.
Hi again...
It was long time ago but I'm slow, and saving money takes time. So, first I want to thank all of you for your responses, and for you Cerrot for the invitation. Actually I had an opportunity to hear the system at NJ, an excellent experience. 
I purchased the 10e system. The setup is not completed yet, but I bought a full system from Roger. 
Thanks, lmomo
Congratulations! I heard the Sanders system at last years T.H.E. Show, and for the first time in years was filled with lust for a new speaker. They are really, really good.
Thanks, this model is a new one and includes a new crossover: DBX Venu 360, with an option for room correction. 

Lmomo,

Thrilled to hear you got the system!  I have a DBX Venu 360 on the way from Roger!
