I prefer to trust my own ears and not something which was written by a guy (Tyll) which is proven as a lover of Audeze headphones which are definitely not neutral or natural.
Okay the mids and treble are slightly better out of HE-500 compared to LCD-2 but for me not good enough compared to HD800.
And bass ... regardless which drums you are listening to, out of an Audeze headphone they sounds always the same. Booom ... long and deep but not dry and fast.
The HE-500 is a little bit better than LCD-2 but for me the dynamic of HD800 is much better.
Nevertheless all 3 are great headphones with different soundings :) !
Again, I'll agree to disagree. But, this is Head-Fi, it's to be expected. :)
