Looking for suggestions/help with DAC/AMP purchase

[Haqal]

Howdy,

Been visiting the site for about a month now, slowly getting into the scientific audiophile world more and more. I have a pretty basic set up right now, but I'm planning on purchasing some more gear soon, hence the thread.

I'm going to get a set of Monoprice m570 planar cans. I'm looking for a dac/amp combo that will drive them well, preferably a portable set up for use with an iPhone. If at all possible, I would like to be able to bypass the amp in the unit so that, down the road, I can experiment with tube amps.

Thanks in advance!

Just a self update. Having played around with the reviews sorter thing, it seems like my top options would be: Fiio Q1 Mark II (unclear if can be used with an external amp), Qudelix 5k (some worries if this can dive the m570), and the E1da 9038S/D (some worries about iphone compatibility). Narrowed down to these, anyone have recommends or can clear up the worries?
