I just bought the Mr. Speakers Mad Dogs, these are my first audiophile grade over-the-ear headphones. I've read they need a lot of power which makes my search for a portable amp/dac device so hard, especially because my budget is limited to $200.
First I thought I'd be well of with a fiio (e7, e10, e17), but reading several posts that say performance is just to low I had to look for something else. I'm thinking of the ibasso d-zero right now.
