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.

what's the difference, 2 db? Audibility is doubtful

no personal experience though- I run a 250.8 which has power to spare
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
