I have listened d7200 yesterday with fiio k5 + x5 3gen as a dac. Honestly I wasnt impressed at all. I was expecting more for this price.. but it looks so nice, especially those wooden cups

Thanks for reply. It looks like more expensive amp wont make these headphones sound noticebly better? Also im thinking of buying fostex th610. They are also easy to drive. And what about balanced out? Is it worth looking?

Hey guys. I have fiio k5 amp and im looking for an upgrade to something much better. Im willing to spend 400-600$. My headphones are: bd dt770 80ohm, hifiman he400i and will have m1060 soon. So maybe i would consider buying amp with balanced out. I was thinking about fostex hp a4bl or aune s6...
