For the original poster's benefit:
I would recommend the XA100.5, but not the XP20. Although I voiced my opinion clearly for the XA30.5 with the Sophia II's, I think compared to the rest of your system, the XA100.5s would be the best fit. I think you would appreciate the difference between an XA30.5 and the mono XA100.5s and you would be willing to pay for the improvements. In my situation, the XA30.5 fit the bill just fine both financially and sonically (and it allowed me to purchase a tube amp to swap out during winter months or when the mood was right). The XP20 is very good, but you really should pair the XA.5 series with a tube preamp as it will only add to and enhance the sonic purity of timbers/harmonics you get from the XA.5 series.
Hope this helps.
