Does the LP-2020A+ Lepai Tripath Class-T Mini Amplifier provide enough juice to these speakers to at least enjoy them to respectable levels? It says it provides 20W per channel, but it probably can't match the description at 4 Ohms that these speakers run at. Is there any other sub $40 speaker amp that provides enough juice to these to enjoy them until the amp from CEntrance comes up on massdrop?
