In Reply to: If Class D isn't digital, then what is it? posted by Tre' on June 27, 2025 at 09:10:39:
for Class D, an analog input is expected, which is compared against the Class-D output.for Digital, a digital input is expected, which is compared against the Class-D output (after a digital-to-analog conversion).
So, a Class-D amp can take advantage of a better DAC providing the analog input.
The Digital Amp, on the other hand, can take advantage of less analog circuitry, but the digital conversion is baked in already.
In conclusion, the Class-D amp is just a comparator and an on-off switch while the Digital Amp has a built-in DAC, but the rest is the same.
Hence, the popularity of both: Digital amps are simple and efficient. Class-D amps properly cater to the higher-end category because of it's flexibility that is not 'pre-baked-in'.
