I think the makers of the HE-6 actually revel a little bit in the notoriety their baby has gathered as being a pain-in-the-backside to drive.
Do you think in the future, other headphone makers will make headphones much harder to drive than the HE-6, either purely as a by-product of the necessity in their designs, or, because they think consumers will equate needing a huge and over-powered amp to drive it is a sure sign of a headphone's audio-fidelity?
Basically, if I buy an amp powerful enough for the HE-6, will I be future-proofed against all (non-electrostatic) headphones that will be released before I die?
