Tried out the kz an01 on both kz prx and my old zsn pro. The zns pros are significantly louder than prx, which means prx needs much more power to drive them, right? Well I took it to the official website to look up the impedance of both of them and to my surprise prx has a lower value!

So the question is shouldn't it mean that, prx needs less power to drive? Or the reason is in technology? Prx is planar, while the zns pros are hybrid.

Sorry for the dirty table, I really wanted to glue up some stuff real fast and made a mess :c
