I'm not that great writer, i can't write a good comparison in my native language, so in English, is almost impossible for me
So in some threads about the Aeolus, some people say its like a super HD650, and the same thing i can read about the Empyrean.
What i can say is: Empyrean and Aeolus are so similar, so i think about to sell my Aeolus!
I'm waiting on my Arya, i think this one and the Empy will be a good pair together.
After 10 hours of listening, all i can say is, the Empyrean is all i ever was looking for!
Had so many cans here in the last six months, Hifiman HE1000se, HE1000 v2, Audeze LCD3, but for me(!) they are all not worth the money!
The Empyrean i take on my ears, and the just blown me away - the best Headphones i ever listen to.
Now i have to look for some nice custom cable, after all i read, i decide silver cable are the best for these cans
