Yes it more than enough in impact and punchiness. It has the most neutral bass of the three. The other two amps have a more "fun" bass. A metaphor would be all three are like cars with V8 engines and 0-60 times under 4 seconds. But the Lepai and Baby Sophia are under 3.5 seconds and the Emotiva is closer to 4 seconds. In your everyday driving you wouldn't ever realize the difference unless you went head to head with one of the other cars from a red light. Same here. You wouldn't think the bass could get even more punchy or impactful until you listened next to the other amps. And for reference the WA7 and other underpowered amps would be like a Toyota Camry.
