Don't get pushed by some of the above posts into thinking you must have 350wpc, 600wpc, 1000wpc, 1,200 wpc. And the post above misstakes my experience that the Pass x150.5 was inadequate - wrong!
Of course, if you want to spend the $$, then you can't go wrong with a higher powered amp, other things being equal.
But, as I said above, it depends on how loud you play the maggies. The Pass 150.5, as I said above, is really a 250wpc amp disguised as a 150wpc, as per the Hi Fi News tests and is much more than merely adequate.
My 150.5 has more power than my prior Classe CA-201 (stated as 200wpc). My friend's 150.5 had, in his opinion, more power than his prior Classe CA-401 (400wpc), particularly in producing deeper more powerful bass than either of the Classes, which both of us felt were somewhat on the soft side on the bass. The Pass was better in all other categories also - detail, transparency, etc.
But, if you are unsure about the 150.5 and want to ensure adequate power but not go overboard on the power/price issues, I would say you can't go wrong with the Pass X250.5.
