I wanted to thank Brooko for posting the audio frequency response graphs here of the latest HiFiMan iem earphones, particularly the one for the HiFiMan Re-800, which is near to my perfect ideal sound signature. It helped me in my decision to purchase the Re-800.
Although, I'm curious Brooko of your impressions of the Re-800, as I really like mine, all except that I'd like for their to be a bit lighter bass and a bit more forward mid on the vocals. I was using a Zorloo Zuperdac for it, which I read adds +4ohm to iems, and makes the sound more bassy. Even the Fiio you used I read can add a bit of an extra bassy signature.
So, I'm hoping when I get the Meridian Explorer2 on Wednesday, it will help reverse things slightly between the bass and vocals. From what I've read online so far, it seems the Meridian Explorer2 is mostly neutral on the bass and makes the vocals slightly more forward with a bit of extra treble. This may make the Re-800 perfect for me. I'll post my impressions of it in the Re-800 thread, and I may write a review of my own for it.
Anyways, I recently had a designer create an audio frequency response graph showing my perfect ideal sound signature. I'll try posting it here to give an impression of my preferences for audio sound :
