And yet the most balanced orthos are the ones with average sized drivers. The T50v2 (and clones) with these massive drivers have extremely poor treble response.
In the world of electrostats, where the SR-007 driver isn't that big, it probably has the best bass, extension and depth of any electrostatic headphone.
It's all good in theory that large drivers = good. But it has to translate into real world examples as well.
