I have heard it said (e.g. by
@GoldenOne) that the HEKv2 is "easier to drive" than the Arya in the sense that it doesn't need need as much power to shine as the Arya does.
I'm consider getting an HEKv2 to pair with an amp which can put ("only") 258mW & 3Vrms into it.
Now, given the impedance and sensitivity of the HEKv2 (35ohm & 90db/mw resp.), this power will drive it to
114.1db, which is obviously much
more than listening volume:

Would such a setup be "enough" power for the headphone? Obviously it is enough power from a pure loudness perspective, but would the HEKv2 benefit substantially from "excess" power being available, such as the Arya reportedly does? Or would it benefit, but to a lesser extent than the Arya?
P.S. I know I didn't explain what this mysterious 258mW amp is, but I can if there is interest.
