Happy Easter to ghdprentice too always a good adviser for all ....
@mahgister "...The most difficult factor to get from an headphone is a natural timbre..." I agree.
For me the thing that completely changed the game actually moved all the headphones way closer to natural timbre and power was the headphone amp. Suddenly the Focal Utopia, Sennheiser 800 and others sounded much more alike than different. And so much like my main system in overall presentation, tonal balance, power, and satisfaction. Obviously there remained specific sonic location differences, but they just don’t seem important anymore.
