The sound of Class D amps are not everyone's cup of tea. Certainly not mine. I had a C316BEE in a secondary system once and it did a great job driving a pair 6 ohm, 86db speakers. Very musical and punches way above its weight. Lots of line level inputs too. I am sure it would do a fine job with your Zensors.
And besides, even if the D3020 wasn't Class D, I personally couldn't deal with the D3020's looks.
