Ok so what amp would you suggest for the 780's?

Thanks Sonic Boom. When I went looking at these two headphones, common consensus was that the 780's had better bass than the M50's, is this true? Also, what would be the best amp to get for them? Thanks!

First off, i apologize for any mistake I make here as I am new to Head-fi. Secondly, I'm new to the world of headphones, but have dome researching and found some over ear ones that I hear are good. They are the Vmoda Crossfade Lp2, the Shure SRH750 dj, and the Audio Technica ATH M50s. However...
