I hope it works fine with my Macbook Pro and iPad with an Apogee One for on the road. Price is not in issue if it delivers the quality and is very easy to drive. I do believe speakers / studio monitors are better at home use, hence why I'm not investing in headphones that are difficult to drive like the HD800.
I'm also interested to hear how much better the AKG 812pro is in comparison to the Shure SRH 1840 (which I'm currently using). I'll be looking to upgrade from these headphones if the difference is signifcant enough.
