I am very interested in purchasing the HE-400's but have three questions. I listen to FLAC and Apple Lossless files from a Macbook Pro and iPhone 5. I listen mostly to jazz, classic rock and classical.
Can a Dragonfly adequately drive the 400's from a Macbook?
Can a Fiio e11 drive them from an iPhone?
And, maybe most importantly, I listen to a lot of electric jazz(Jaco Pastorious, John Scofield) and funk. Can the 400's deliver a strong bass slam when called for?
Thanks for any advice.
