Whether it's a DAC or speakers, when comparing two good alternatives, I doubt most of a big price difference is in the parts.
Many high-end products are built more or less to order in small numbers, for affluent customers willing to pay a big premium even for relatively small differences in SQ. The company may not be over-charging for its product. It really does cost more to make, deliver, and support it. But not (primarily) because they use vastly more expensive parts.
Recently I looked at Devore speakers. $8400 for the O/93, $12K for the O/96. Plenty of decent, 2 way bass reflex boxes are available for far less. Devore uses veneered plywood baffles, not MDF. Sure, veneered plywood is more expensive, but not THAT much more.
