I think Fang confirmed indirectly some pages ago that HE560s have a newer generation of diaphragm membrane, that is much thinner than previous-gen Hifiman planars (he was answering why there are holes under the retail HE560 storage boxes, that it was to maintain a pressure equilibrium to protect the ultra-thin new membranes). That is indeed how it gets the increased efficiency despite single-ended design, and probably the exceptional overall resolution and decay too.
