Last year, I auditioned my Montis speakers with an Accuphase E650 integrated amp. This was a wonderful match.
I can’t comment on Pass Labs, but the Accuphase amp has similar specs: 30 watts in Class A into 8 ohms. (60 into 4, 120 into 2 and still higher into 1).
Not all amps are equal, but power will not be the problem here.
