Pass Labs upgrade?


Hi,
i am looking to hear from anyone that has/had the Pass Labs XA-60.8 amplifiers and upgraded to the Xa-100.8 amps. What was your experience like ? Was it worth the leap?
my speakers are pretty efficient @ 91 db but I am interested in the next model of Pass Labs for potential increase in overall dynamics.

I also own and love the X250.8.  I am told that the XA100.8 is better sounding than the XA60.8 even at lower power levels...
In the same vein, I would interested in reading about those who went from the .5 to .8 power amps as well. Happy Listening!
I went X250 to X250.5 then X250.8 over 12 years...each was a significant improvement with the same signature sound
the X250 and X250.5 also had some upgrades along the way before the model number was updated
I have Wilson Sasha   Upgraded from Xa 30.5 to xa 100.8.    Now saving to upgrade to  xa 160.8.    Sasha needs more power.  The 100.8 delivers more headroom and bass control but just not enough in my experience.
