I use a Class A amp that outputs 40 watts but will drive just about anything - they were driving 1 ohm Scintillas when I bought them, and one of the currently drives a pair of speakers that are 86 dB efficient.
I don't know those Pass amps but I do know their reputation and would bet that you would have no trouble driving your speakers with them.
