A (Belated) Christmas Miracle: Moondrop S8:
Oh boy, if this isn’t a review that’s been delayed to hell and back. Throughout the year I’ve tried (and failed) to find time to review the S8, and it’s kind of become a running joke of sorts. But on the very last possible day (because shops are closed on the 31st, duh) I dragged myself out to give it a proper evaluation, complete with comparisons to IEMs the S8 is often mentioned in the same sentence with. I suppose it does no good to delay the already belated review, so best to get right onto it.
Being a full BA, bass on the S8 isn’t exactly a strong suit. I mean, it’s not extremely flabby, and it has decent impact for a BA. But comparison with the much cheaper (and not all that resolving, bass-wise) Blessing 2 shows a pretty severe deficiency in bass texture and decay. It’s probably nitpicking, but something about a cheaper budget model outperforming a model that’s, at the very least, upper midrange, strikes me as off. I would rather Moondrop have placed their hybrid at the S8’s pricepoint and their full BA at the B2’s pricepoint, but I digress. There’s certainly worse in the BA bass department, but this is hardly worthy of standing next to the likes of the Violet or the U12t.
Ah yes... the midrange. Where the music lives, so to speak. The S8’s famed midrange is... pretty good. I mean, it’s a little shouty and a hair too forward for its own good, but that aside, it has a pretty even balance and it doesn’t sound too lean like many other Harman inspired tunings tend to be. Directly against my Viento-B CIEM, I can say that it’s a little more forward, but at the same time perhaps a bit more full bodied. I think the Viento’s frequency balance is more even, and the S8 potentially being too midcentric, but this is hardly a dealbreaker. They’re certainly not identical despite what some may have you believe, but I don’t think they’re too far off from each other. The B2, on the other hand, sounds almost V shaped in comparison to both the S8 and the Viento, though much more so with the S8. It’s not terrible sounding, but it makes it seem unrefined in comparison. To put it in short, the S8’s mids are pretty damn competent.
And now the treble. I previously lambasted the B2’s treble for a perceived level of sharpness in its treble. Graphs don’t really account for it, but upon further review it does feel more like a transient behavior than a frequency one, which makes sense. This is especially apparent with violins, where it sounds more like an overly sharp attack with slightly ringy decay. With cymbals it more sounds like there’s a peak somewhere.
But this review isn’t about the B2. It’s about the S8. The S8’s treble makes a first impression of not being as rough and scratchy as the B2’s, and it’s actually quite nice to listen to all around. Further listening, however, reveals a couple of caveats. Firstly, that there appears to be a similar sort of a treble behavior between the S8 and something like the U12t, except less extreme. By this I mean that there is a mild mid-treble dip with some comparative emphasis past 10khz. Graphs corroborate this. As for whether or not it sounds bad... eh. It could certainly do to be a bit more even, but I don’t find it sibilant or sharp like the B2, or slightly splashy or resonant like the Viento is at times. I think it’s a decent compromise between having a good level of energy and extension while still being smooth.
Intangibles are the downfall of many an IEM, and countless well tuned IEMs have met untimely fates when faced with the categories of dynamics or detail retrieval. Well it’s best to just put it upfront I suppose: the S8 isn’t bad intangibly, but it’s not mindblowing either. I suppose it’s unfair to start off with comparisons to IEMs 2-3x its price, so let’s compare it to the B2. The B2 was kind of in the upper middle of the road in terms of dynamic performance, that is to say, not awful, but not worthy of standing at the top tier either. The S8 is a tier below the B2 in macrodynamic swings and microdynamic delineation, tending towards loudness compression. In particular, on music that I know well from regular listening with the U12t and Utopia, it lacks nuance. The B2 is equally lacking in microdynamism, but performs better in large dynamic swings.
Where the S8 succeeds and the B2 fails, however, is coherence. The B2 had a notable issue with coherency throughout the frequency range; the slightly smoothed over bass was too slow for the slightly recessed BA midrange, which was in turn mismatched with the scratchier and sharper BA treble. The S8 has none of this. It’s overall very coherent from top to bottom; perhaps not as much as the Viento, but enough to give it a run for its money. I can appreciate this a lot. As for detail retrieval, the S8 seems to perform as expected for the price. Certainly behind the Z1R and U12t, but better than the B2 (in part thanks to the clarity that cleaner treble and fuller mids impart) and about on par with the Viento. Microdetail is the main department where it falls behind the U12t, but barely any IEM is good at microdetail anyways so this is effectively a nitpick.
Staging is an interesting one. The B2’s stage was commented by some as feeling more open than other IEMs, somewhat surpassing the sonic wall if you do. On further review, I can hear what they’re saying. I’m not sure if I agree entirely though. It certainly does have a degree of openness and a level of out-of-the-head staging, but I don’t know if this is enough to truly consider it as having surpassed the sonic wall. The S8, on the other hand, is firmly within the sonic wall, and its staging is stuck within the shell. Kind of a shame, but it is what it is. Despite this, I think the S8 layers better than the B2. It’s surprisingly competent in this department and does a good job at capturing stuff in the mix that might otherwise be buried. Interesting how these things work, and certainly a point of merit in the S8’s favor.
But I think the million dollar question is whether or not the S8 has its place with the B2 providing strong competition at a much cheaper price point. And I think... yes, it does. It’s more coherent than the B2, with a cleaner treble response, and better technicalities across the board. These might seem like inconsequential nitpicks, but I think they cover the remaining ground that the B2 lacked in regards to being a true kilobuck competitor. In this sense, the S8 is the flagship competitor IEM that many people hyped the B2 up to be, but I certainly didn’t think was worthy of. What I would really love to hear is a fusion of the S8’s refinement in the treble and coherency with some of the B2’s more oddball characteristics, like the DD bass and the slightly out-of-the-head staging (which I personally suspect might be thanks to the vent on the shell, which is almost definitely for the DD). But I digress.
Of course, it’s double the price, but I think that someone who likes the VSDF sound may be hard pressed to find better elsewhere given Moondrop’s failure to follow up on the S8 and B2. I don’t think the Viento is a true upgrade path, as it accomplishes different things as a whole. To this end, I’m going to say that the S8 is recommended, and deserves to be placed above the B2 in terms of scoring.
All listening was done out of the WM1A’s 3.5mm jack.
Good note to end the year on, I think. I was almost going to cover the new Campfire DDs, but I would rather not end a bad year with a review like that. Best to keep things a little positive and hope that next year will prove better.
Score: 7/10
