After doing some more reading (hours and days spent reading various reviews of headphones) it seems like the Ultrasone Pro and Proline 750 are the same headphones. I'm now bouncing between the 750 and 2500, although I've never heard the 2500 I do like a good soundstage so I'd assume the 2500 would be superior because it is an open can. I've been through many threads and searched around but haven't found a decent comparison of these two cans if anybody could chime in.
Also I've read that these headphones require a good source. How would they do with a portable amp like the ibasso D12?
