Any Rogue Zeus Owners Out There? What Preamp?

I am considering the Rogue Zeus tube power amp and heard that the Rogue M99 preamp works well. I heard the 99 preamp in another system back a few years and thoguht that it sounded fine for the money but I would have liked a better sound, kind of bright compared to some other preamps I heard and not as magical in the mid range for a tube preamp as I would prefer. But I have never heard the combination of the Zeus with this preamp.

If you have the Zeus, what preamps did you try and if you have heard the Zeus at a dealer or somewhere, what preamp was the beast mated to?

Thanks and Happy Listeing.
