I am having a ZS5 bought in November 2018. I am very satisfied with it, sounding great with a Yinyoo 8 core cable Those who have both the ZS5 and the ZS10 Pro, what is your opinion, which one is better? Is it worth to upgrade from the ZS5 to a ZS10 Pro? I was thinking to try an all BA IEM so I am waiting for the AS12 reviews to come. Any of you compared the ZS5 and the AS12?
