I will assume it uses the same IC based topology that Mac has used for decades but with surface mounted devices (SMD) instead of the tried and true through hole devices. If you are a firm believer in the sound quality of certain types of say, capacitors, (Electrolytic, Mylar, poly this or that, tantalum etc. etc.) this might be a issue as the selection of SMD types are more limited than through hole. Time, basic testing and reviews will tell.
