Pass may rate it at 30 wpc (its pure class A rating), but looking at Stereophiles measurements, it puts out 130 watts into 8 ohms and 195 into 4. It's transitioned to A/B but more important, it's not clipping. So on paper you might not think it's enough power but under the hood it's more than you think. Still might not be enough for "you", we don't know how much spl you like.
