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?

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!

Another +1 for the Sanders preamp, it is very revealing, and adds nothing to the signal. It’s very open and pure. 
I love mine.  With proper recordings, it is flawless.
