I've got the Pass Xono with the XP20 and XA.5 amps. It' a good match. I've read that the XP15 is better than the Xono and the XP25 is a significant improvement over that. Remember that one convenience of the XP25 is the easy loading via front panel knobs. Spend some time finding the best settings for your system before making any buying decisions. Also, these units are meant to be on 24/7 and I was told that to sound their best they need to be on for a few days at least, so keep them both plugged in while evaluating their performance. You might also want to contact Kent at Pass for advice.
