Audio Research or Rogue

I'm fairly new to tubes and after about 200 hours I am pretty happy. However, I'm considering a new pre-amp to get phono and the potential for even better sound. What are some opinions regarding an Audio Research LS-16 MK2 and a Rogue 99 Magnum? I know little more than the experienc of my Dared class A, and frankly I'm very satisfied with it. My upper end is driven by an SET 845 into original AR9s. Most of my listening is classical. I probabaly like my music louder than most(she never complains)but, not excessive, I also like my hearing.

Thanks in advance for your feedback.
