Class an vs class d

Thinking about new amps, the new parasound jc1+ vs the mola mola . I realize a bit of apples to oranges, both similarly priced, both mono blocks, both the latest technologies in their respective output classes

At that level of quality and expense, the only way to know is to audition them in your own system. I don’t believe anyone on the internet can tell you anything very useful to making a choice.

As @erik_squires said, the class is irrelevant. Both Class D and Class AB have been used to make wonderful amps. The key differences are in the engineering quality, not details of the circuit.
The class is irrelevant. How they play with your speakers matters. You should talk more about your speakers and preamp.
