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

2-11 VOLUME CONTROL:
"Channel Balance – All pots have some channel balance error. Due to the logarithmic nature of perceived volume, and the way voltage dividers work, the channel balance error will be greatest at the lowest volume settings. And it’s different for every pot. The dScope has a real time channel balance measurement so you can literally turn the pot and watch the number in dB change in real time. It’s not uncommon for the louder channel to swap back and forth as the pot is trying to average a 0 dB error over its range. The dScope makes it relatively easy to find the worst case imbalance and it’s nearly always in the first 5% of the range. The key is to intelligently set the gain so you avoid using the few few percent of the volume control’s range."
The other portions of 2-11 are also relevant and interesting, but he isn't know for his brevity, so I will limit myself to the quoted bit :)
