I had the XA30.8 for while driving Spendor D7.2 towers in a medium / large room sitting 10 feet away and there were no issues with power availability. The 30.8 puts out 120 watts at 4 ohms and is 2-ohm stable.
Your speakers are lower sensitivity than mine (86.5 db vs 90 db) which will be a factor as well as a 2.6 ohm impedance dip at 93Hz. Not a miss-match on paper at least.
Your combo will make sound and music. Whether the Pass XA30.8 has enough to satisfy depends on your room size, how far away you listen, your musical tastes and your listening preferences.
If your room is large and you listen at a significant distance you may have wished you asked this question before you bought the amp.
