I had the FH9s for a while and ended up returning them. They started making a weird noise on the right one. So I sent them back to Amazon. I did think that they sounded really nice on the M6 Ultra. In fact they sounded as good or better than my Ananda's. I don't have a high end set of IEMs right now. I am going to look into your recommendation here.I thought the M6 Ultra + Fiio FH9 was endgame for me, then I tried the IER Z1R and had that definition reset. The smooth presentation of the M6 Ultra really let both of these IEMs do their thing.
