Pass Labs AMP’s- What is the best Pass Amp Sound for You from past 10 years


So I have an XA-25 and its outstanding. I’ve tested the XA60.8 mono’s and there was not enough difference to move to them; no jaw dropping moments. Don’t get me wrong they were fantastic, but so is the XA25. Looking at the 350.8 or 250.8, etc.... even in comparison the Integrated INT-250... If you love it; want to explain what you like and why? I’m wondering what others are thinking... 
My set up: Wilson Sophia II’s, XA-25, Pass Labs XP-22 pre, Merging+NADAC.

@karmapolice, your point has much merit, but meters on gear such as this are almost never calibrated measuring devices, more often than not just glitzy toys serving as eye candy. Such meters rather than giving insight more often than not mislead.
I have an X250.8 with Sophia 2's. I'm very happy with the combination. Very natural, organic mids and highs, and excellent bottom end extension and weight. Slam is very good (but not a Krell). Outstanding, realistic 3D imaging. I think the Pass brings out what the Sophia's do well without exaggerating anything or making them fatiguing.

Upstream it's an ARC Ref CD8 into an ARC Ref 5SE. The Pass works really will with that. Very happy with all of it. 
The only one I’ve ever owned, an XA30.8.  Love it!
Has anyone compared X250.8/X350.8 to the X260.8 monos?
Will be used with Maggie 3.7’s.

How much better is the XP22 compared to XP12?
