The high-end companies like Esoteric, dCS, Nagra, MSB, Aurender, etc might be doing better here compared to the Chinese who have come very close, if not equal or better to the high end companies regarding hardware quality. That might change in the future though.
If done right, the SMPS power supply could be as good as a linear one. IFI, sotm etc do make SMPS PS for audiophiles.
