Are Pass Labs XA60.8 mono amps enough?

Hello everyone,

I plan to buy a class A Pass Labs monoblocks pair for a Focal Scalla Utopia system. These speakers are very easy to drive (92.5 db sensitivity)

I'm interested in the XA60.8 model. I wonder if it is worth waiting to have the budget for the XA100.8. If so, why?

I'm 25% home theater / 75% music. My room is rather small: around 230 sq. ft. I don't crank up the volume very much

Thanks for your help

I asked Pass about this when I was interested in the 260.8 monos for my 4 ohms Maggie 3.7’s.
