Don't know, but I know the Fiio E17 definitely can drive a fun level and maybe to an extreme level - it will drive your Pro700mk2's also.
It is the Audio Technica Pro700mk2's you're getting isn't it, or Pro500mk2?
You do realise that these are DJ headphones (500 & 700 series) with a clamping force strong enough to extract juice from lemons?
Even melons, if you have a big head...
Are you going to do a bass paper test video also?
I know I had a lot of fun making my test viddy with these cans...
