Today,I listened DX90 in our forum meeting..I compared with my AK100.With my musics.And I love AK100 more with IE800.
And I think,DX90 and AK100 are so close.DX90 can be harsh and it has more open sound signature.
But,AK100's mids much better than DX90 and AK100's background is more cleaner.
I think DX90's only plus is power.
About other things and in sound AK100 is better with IE800.
I wanted to write my impressions.
I think,I will buy AK120.But,it not certain.
can't be more agree. love AK100 for the neutrality. and all DX series that i tried always sounded harsh to me. DX50 DX90 DX100.
