Direct to the right forum or if you can sum it up for me, it'd be a big help.

I have no experience with either, however my understanding is that the Fuse has a very good quality headphone output, with a very low impedance, and would be able to generate approximately 10mW into those phones, producing an SPL of 115dB, which is very loud.  So my educated guess is: no amp required unless you need to change the tone for some reason.
