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.

I have the 260.8 monoblocks. I have never been happier. They stay in class A till about 34 watts.

jtucker - Can you comment on the INT 150 sound? 
douglas_schroeder  - I spoke with Nelson Pass when I wanted a First Watt for the Wilson Sophia's and he directed me to the Pass XA-25. Said that it was a mix of First Watt and Pass; something that First Watt just could not execute like Pass can so it became Pass XA-25 and recommended I try it first. 

Thanks for jumping in markum01, I was hoping somebody would mention the 260.8 monoblocks, which are sort of on my radar.  I assume the 260.8 monos offer as much as the 250.8 stereo amp, plus some? Any comparisons between the 260.8 monoblocks and the 350.8?
I am currently waiting for delivery for my first (and hopefully my last) amp upgrade. I elected to go with the 260.8 mono's and Tuesdays delivery cannot get here soon enuf
