Madfloyd,
I upgraded my XA160 to the new XA100.5. They have much better control of the bass on my Eggleston Rosa (87dB,4ohm min) and drive them to satisfactory levels in my smallish room (200watts at 4ohms). You may want to read a review on the Pass website by Dr. Peter Poltun comparing the XA.5 to the XA. The Vienna Archives uses Pass and Wilson WP8. The XA.5 are truely special, but I'm biased.
