@Currawong Thanks for the comparison you made in the video. I wonder why the word 'transparency' is not used as much in reviews, which you indirectly alluded to when going from dynamic drivers to electrostats and planars with very thin diaphragm such as LCD-5. While tonality and clarity are only part of the equation when it comes to 'micro-detail', time resolution is what allows low mass drivers to provide a bigger window in to the music by allowing us to notice subtle changes and impart realism that we naturally and instinctively expect in sounds we hear in real life (because of physics involved) similar to how you described the shakers. It is not just tonal in nature but the nuances that can easily be mushed together in time if the driver is not nimble enough.
As someone who chases transparency, one of the advantages LCD-5 offers over competing headphones is the ability to to be driven directly out of high quality integrated Dac/Amps. I personally avoid adding an amp to my chain if I can, as it means additional interconnects additional amplification/elements, additional PSU all of them stack up and do reduce transparency just like additional elements in a high quality lens (as an analogy in photography). But to my ears LCD-5 driven direct out of Chord DAVE or TT2
is can be more transparent than a electrostatic setup that adds an amp to the chain. I am not saying everyone should abandon using amps, I am providing another point of view for those who may value transparency more and are willing to give up a little on other aspects that an amp can bring.
