jlmcorpuzI'm not familiar with the Hisdiz A60, but the Fiio A3 should provide enough power to run these well, but not at 100% of their potential. I've been using them with a Fiio E18 myself and recently tried an O2 Amp which definitely had stronger bass and more clarity, but on the other hand I've also been perfectly happy with the E18 and even my smartphone. These headphones sound good out of most sources but will continue to improve as you move up in quality.
