Duelund caps in my Merlins. Prior to the Duelunds I perceived increased treble extension as brightness, after the Duelunds I hear it as simply treble extension. I would describe this brightness as a hardness in the treble, now have a silkier, more airy presentation. Furthermore, I've found cap upgrades throughout my system have imparted a much greater level of refinement to the treble (as well as the mids and bass).
Clean AC is also critical to attaining refined treble.
And I agree that as I've gotten older, anomolies in highs bother me more. I hear pressure and discomfort in my ear with any discontinuities in highs.
