"It depends" is the best answer because it involves a lot of
factors including personal preference. Mentioned class D amps are in big
part based on modules that have low input impedance (for many Icepower
modules it is 10k). My class D power amp has additional input stage
increasing input impedance from 10k to 40k. I use it with Benchmark DAC1
direct, with great sound. I believe that additional component in the signal
path will always cause some loss of transparency but often can change
sound to your liking (in addition to impedance matching). No right or
wrong here
