@PGAMiami If you are new to IEMs, maybe consider something a bit cheaper to start.
I wouldn't personally have picked the FD7 either, the FD5 is not well tuned (I have it), it's much too boomy and then sharp, piercing and uneven in the upper mids / treble. The FD7 does look like an improvement, but there are much better options at that price range.
Empire Ears Odin is extremely expensive but also very well regarded, and widely so, many different reviewers I trust the opinion of put it close to the top of their rankings. Graph looks broadly correct. Having multiple drivers isn't necessarily a problem.
I don't get the impression that JH Audio is particularly well regarded among IEM audio people. Maybe more specifically stage performers, I get the impression that's what they are targeting. That graph looks terrible, look at the huge dips in the upper mids and then again in the treble.
But if you are relatively new to IEMs I wouldn't jump in at >$3,000.
There are severe diminishing returns with IEMs and there is some really good stuff for relatively little money.
The Moondrop Blessing 2 Dusk really is excellent, for only $329. This would be a relatively low price to test whether you think a multi-driver config could work. The one weak point of this is the treble, it's not bad but it's not the best you can get. The rest of it, pretty much is there, it's excellent.
Other stuff I like:
Planar: Shuoer S12, 7Hz Timeless
Single DD: Moondrop Kato, Dunu Zen, Sennheiser IE600
Tribrid: Moondrop Variations, Thieaudio Monarch Mk2
Multi-BA: Moondrop A8, Sony IER-M9, Symphonium Helios
