I have the CDM1NTs in my system and have found that they do perform better with an amp that has some heft/watts.
In your case, "well enough" would depend on how big of a room your speakers are in, where your listening spot is, and how loud you like to listen. Will the 3020 work? Sure, but imho, you would do better with a bigger amp to unleash the potential of the CDM1SEs.
