Has anyone found a portable amp that can really power the Mad Dogs well? Going to be using mostly with iPhone 5 but willing to make the switch to iPod classic if necessary. Assuming I'll also need and LOD and maybe a DAC? I'm not too sure. Also a side not, I'm not too sure of the difference between the three types of Mad Dog cans for sale - one is 299.99 one is 339.99 and one is 399.99. Something about Universal Mad Dog and Balanced. If someone could help enlighten much would be appreciated.
EDIT: Price is considered but can be a good amp. I'd like to get some open cans for desktop listening in the future so I'd like the amp to grow with my headphone collection rather than have to upgrade with each new pair.
