Bump

I can detect it even in a normal volume. My god! My ipod is going to die? But it is ok when i am using the B&O A8. And if i adjust the e5 inserting angel. Turn clockwise or oppsite, the noise will dispear in some position.

Anyone give some advice regarding Corda HA-1? I do appreciate Jan's build qaulity. But how does it work with E5? Anyone try?

Thanks everyone! I got a Total Bithead. But the hiss is terrible. Micro desktop AMP should be my preference. I dont want another mobile amp. The total bithead is fine with my HD590. Now i am considering : Corda HA-1 MK2, Jan said he can reduce the gain factor to reduce the noise, but i worry...
