More significant changes found in AP80Pro housing compared to its predecessor: design got more complicated and definitely consumes more CNC machine time. Side edges became curved, new shape around volume knob makes it easier for access.
Performance and UI:
AP80Pro is based on HiBy OS 3.0 and Ingenic X1000 CPU. This combination stays unchanged since the initial release of AP80 DAP and still demonstrates smooth behavior of the user interface. First scan is very fast even with 128GB cards full of different format tracks, all operations are quite snappy.
