How does it compare to Raptgo Hook-X?
Two different pricepoints and different form factor would be an important thing to keep in mind - these would be quite hard to do a direct comparison in my opinion.

Also they seem to be open back.
and a 2 way with piezo tweeter which can call attention to themselves at times.Also they seem to be open back.
Anyone else try these out recently?
I have. Impressions listed above. Feel free to ask me any questions.Anyone else try these out recently?
Nice review! Love the analogies. Very easy to understand!Introduction
Made an account to give my impression on the CFA Supermoon UIEM. I had the chance to try them out alongside Campfire's Equinox, Solstice, and Andromeda (2020), as well as a few other IEM (64 Audio's U12t, U18t/s, Trio... Senheisser IE900). My preferred music genres include (A-Z): Electronic, Classical, Classics, Pop (English, Japanese & Korean), Jazz, Rap, and Rock. I met with an audiologist for a hearing test a week before sitting down with these IEMs. I was informed that I have perfectly good hearing for my age (20) with very slight deviations for mid frequencies between my left and right ear (no clue if this matters). Do note that my knowledge on this hobby is limited, which my impressions may reflect. I tend to run the Bose earbuds and headphones as a daily driver... Yeah, sorry.
Equipment
I ran the IEMs through a Shanling M6 Pro 21 and Sony Xperia 1 III. The only other thing of note was the use of a CFA Saber 4.4mm cable which is made of pure copper (unlike the Smoky Litz which uses silver plated copper). This had a considerable effect on the sound signature of the Campfire Supermoon. I will elaborate further below.
Impressions
The CFA Supermoon is by far the most interesting option in their "CIEM" lineup. The signature planar sound can be heard throughout the bass and sub-bass with its immediate and at times intense detailing. This detail can be felt at all frequencies with focus on the bass/sub-bass and treble. Furthermore, the lower mids/mids are smooth, carrying a neutral presence in most songs I listened to. The upper-mids and treble carry at times a degree of clarity that may be classified as "technical". High hats, for example, held a high degree of clarity which at times felt distracting to the rest of the soundstage. Although, this may simply be due to my inexperience with non-neutral sound signatures. With these thoughts in mind, the Supermoon presents itself with a V-Signature with extra emphasis on the sub-bass and upper-mids to treble. Compared to the other Campfire CIEMs, it seems to extend itself in the treble allowing for a vaster soundstage.
Another small consideration to the Supermoon would be its evolution through power. The Supermoon is considerably more hungry than the listed IEMs besides the 64 Audio U18-series. It is able to run on the Sony Xperia 1 III rather well, sounding much warmer and musical than when ran through a DAP. This did come at the sacrifice of detail, especially noticeable for the mid and treble ranges. I was able to receive a warmer signature without detail loss on the Shanling M6 Pro 21 by using the Saber 4.4mm cable. The treble took a step back while the mids were brought forward. Overall, I found this more musically enjoyable when considering a varied selection of tracks, but some may finds this deprives the listener of the planar experience.
A Dumb Analogy
Due to my inexperience with audio equipment, I wish to use a family analogy to describe how the Supermoon compares to some of the other IEMs I have tried. The 64 Audio U12/18t are the refined and rather mature brothers who happens to be excellent at everything. They do not disappoint their parents and are often used against their siblings as what they ought to be like. A step down is the Senheisser IE900 who happens to be rather modest. Certainly worthy of praise, but not as acclaimed as his older brothers. The Campfire line-up are, uhhh... Like the adopted siblings. Slightly ostracized; more fun at parties. They are characteristically very different from their siblings while each being prodigious in their own fields. The Equinox is the sporty and outgoing youngest brother. The Solstice is the elder sister who carries a motherly nature. Finally, the Supermoon is the youngest sister who works extremely hard. Her pursuit differs greatly from the rest of the family, but that does not make her lesser.
Summary
The Supermoon is a standout representation of what planar technology has to offer. They hold their characteristic quirks which may or may not be appreciated by their user (i.e., V-Signature and its technical treble). But, most of all, it's a fun IEM. Yes, I did order it. It was a close call between the Solstice and the Supermoon. They couldn't be more different than one another in philosophy. The Solstice felt rather intimate and warm with a beautiful, rounded technical performance. Alternatively, the Supermoon was fast-paced and resolving, with a vast soundstage compared to its other Campfire siblings.
Although the Supermoon is by no means neutral, nor is it as technically skilled as the IE900 or the 64 Audio line-up (the ones that I did try), they carry their weight in musicality and intrigue. I would highly suggest giving these a try. At the very least, they are an interesting and engaging listen. They walk an untrodden path and they do it damn well.
Feel free to ask any questions.
Definitely understand where you're coming from. In my own impressions I made concern towards the V-Shape tuning, which you describe as a mid scoop. I would suggest trying the Supermoon out with a few different sources (you mention only using ADI-2 RME into a Topping A50), because I found it changes quite a bit depending on the source. Although some may be skeptical, I also found the sound change from their typical silver plated copper wire to an all copper one.I've been listening to my demo unit for a few days now. My feelings are pretty conflicted and I'm not certain that I'll commit to a pair.
(All listening done so far through an ADI-2 RME into a Topping A50s. The demo unit comes with three sizes of foam tips, presumably to mimic the isolation of a custom fit, but they were all heinously uncomfortable. Tried Azla Xelastec's, Spinfit CP155's, ultimately settled on a pair of cylindrical silicone tips that came with my Timeless.)
The pros of this pair all fit into the realm of what I'd call "presentation." Soundstage width is very good, depth is as good as I've heard from IEMs (which is to say, not spectacular, but there is at least some front to back delineation) and, most spectacularly, there is actually quite a lot of height, something I personally love in audio gear and have never heard represented to this extent in a monitor of any kind. Layering of instruments is fantastic and imaging is in the sweet spot that I generally prefer; very accurate and well-separated but not to that pin-point degree of something like a Sundara or an ESP-95X (which I personally find unnatural in an unnerving kind of way). Detailing is quite good throughout the frequency range, with enough details through the mids and treble to provide that joy of "wow I've never heard that before" without absolutely stabbing your brain with too much information. Overall, what these features lend themselves to is a large, enveloping sound that is quite addicting. They remind me in their presentation a lot of the Hifiman egg-shaped series, which is a huge compliment from me whose favorite headphone is the Edition X v2.
The problems are all really with the tuning. I don't have any major complaints with the bass; it's very decidedly elevated and that can occasionally come off a little bit "wrong" in quiet moments where the bass is clearly meant to be mixed lower than the Supermoons present it, but it's for the most part very fun and lends itself particularly well to intense double kicks in metal. Texture is surprisingly a little bit lacking; I've gotten more accurate texture from lower-end monitors like the B2D and the Timeless. But the quantity is generally pleasing while maintaining good separation from the rest of the range.
Where the issues crop up is in the midrange. I haven't seen a graph of these yet but I'm gonna guess there's a notable scoop in the lower mids. Hearty textured male vocals (e.g. Adam Gontier, Damiano David, Scott Anderson) lack body and distorted guitars in rock and metal feel thin. This leaves a lot of my favorite vocalists feeling a bit boring, which is a disappointment in itself but still preferable to what happens to female and some upper-register male vocalists. These things can get shouty, something I notice in particular with modern female-led pop (e.g. Leah Kate, Selena Gomez). I would caution that my opinion in this regard should be taken with several large grains of salt; not only am I sensitive to this particular problem, but I find it's exacerbated for me by sets that have particularly wide-bore, deep-insertion nozzles like these universal demos do. However it means that there's some music I just can't comfortably listen to on these, and I'm not ever a huge fan of that.
The treble is more tolerable to my ears than the mids. It's definitely a bit elevated and a little peaky in places. Violins in particular I find can get a little too hot (I'm thinking of the outro in Gazpacho's "Massive Illusion" in particular). In spite of how upper-mid sensitive I am, I don't find I'm all that treble sensitive, so I would say that treblephobes should be cautious with these. I haven't noticed any sibilance in my ~7 hours of total listening, so no demerits there at least. Extension is very good but I wouldn't call it class-leading.
Really just not sure on these. Was very excited by the prospect of a planar CIEM since all my favorite over-ears have been planars and nothing in the IEM realm has nearly captured the same kind of magic for me. In some regards these do live up to my expectations, but the tuning is just not my cup of tea. I do appreciate the attempt to make a custom line that deviates from the very flat, often boring tuning of most other custom monitors but I don't think it really works for me. If anybody has suggestions for other custom options I should look into in a similar price range, I'm all ears.
IEM | Pros | Cons |
Supermoon | Better lateral stage, slightly better vertical stage More defined edges of individual instruments Better bass separation More bass presence, more bass impact Superior upper-mid and treble detail | Sometimes shouty vocals Bright treble does not play nice with some recordings Bass detail actually not amazing |
Solstice | Better body and texture to midrange instruments Less prone to shout Treble never overwhelming Superior midrange texture Better detail in most of mid-range Comparable bass detail | "Softer" edges Weaker instrument separation Tamer treble means less crispiness on cymbals and less definition on some instruments (violins, chimes) |
