I am currently looking to upgrade from my Sennheiser HD439s. After looking, and researching for a couple days, I have narrowed it down to either the Hifiman HE-400 or the Mad Dog Pros (These are new, and are a sort of cross between the originals and the Alpha Dogs). I will most probably get the Fiio e12 amplifier to drive them.
I would only use them to listen to music. I listen to mostly rock, any rock really, from 80's rock to modern stuff like Paramore or Within Temptation. I listen to almost all either 320kb/s or lossless music. I am not a basshead, I like a more neutral sound, so that I can eq it later if I so wish.
All I was wanting to know which one of them would be better for rock music, especially modern rock. right now, I'm slightly leaning towards the Mad Dogs as I could swap them in later for the Alpha Dogs for only $300 more, but any opinions/ recommendations would be helpful.
