I actually liked the edition 9 but it certainly took a little while to get accustomed to. More than the s-logic that takes time, it's probably the very colored mid/highs that come across as weird in the first few minutes... You get used to it though (just like some crave grado house sound).
As for this being a deafening weapon, I don't really agree. If anything, I think I would usually listen to the edition 9 at lower levels than other headphones because if its voicing.
Would be cool to see how all the edition headphones measure, this is such a rare set of data we can look at. Congrats again purrin!
