I'm currently interested in four main options (EDIT: 5, including both FiiO's) in amping these cans to their full potential- of which I cannot say, so I'll let you guys help!
I'm personally more interested in the Dragonfly and the O2, but it honestly doesn't matter as long as it provides good sound found usually in an amp and especially help the bass come along. I know the HD 598's are not meant to be particularly bassy, but some extension and a little punch would be wonderful!
Since the HD 598's are easy to drive and I plan to order the recent shorter replacement cable that terminates into a 3.5 plug, I will be using them for my desktop, laptop and iPod. However, I will primarily use it with my laptop.
Thank you to all that cared to weigh in.
