What would be a good portable Dac/Amp to use with my HD6xx and Sony Xperia 1 V cell phone?
I am new to this hobby. I purchased a HD6XX and plan to use it with my Sony Xperia 1 V cell phone, that has a 3.5mm jack. I was wondering if I needed a portable dac/amp or just a portable amp and if so what would one recommend? Any assistance one could provide, would be greatly appreciated. Kind regards, Haz

With the hd6xx/hd650 theres a strong recommendation for the darkvoice/bottle head/other high output impedance amps. For grados/other low impedance cans low output impedance amps are recommended (little dot 1+/magni 3). But no one mentions amps that have output impedances that match the 150ohm headphones. Going by the 1/8th rule the output impedance should be around 18.75. For example, schiit valhalla is rated at 14ohm output impedance.
I'm currently using my hd58x with a darkvoice and it sounds nice, but it makes me wonder how they'd sound with an impedance matched amp. Would there be better synergy? Am I missing something? Do I need to buy a third amp (currently DV and LD1+)?! etc....
There are a couple forum threads with people asking about this question, but none of the answers were particularly helpful.
I found a review that listed the output impedance of a bunch of other amps too:
