Noble Audio Sultan Impressions
I guess I did say I'd post about this one if I had time. This is Noble's first tri-hybrid IEM, and I believe it's the current flagship of their line-up (or the most expensive, at least).
Overall tonality is something of a mild V-shape or maybe a W-shape. Bass is tokened by a dynamic driver with a pronounced sub-bass shelf that doesn't level off until almost 1kHz. Intangibly, it's pretty decent for a DD. Bass texturing and decay are most definitely present; however, the Sultan's DD struggles with transient control. Notes are articulated with too much bloom for my tastes, resulting in mild bloat. So correction: Decent for a
sub-$200 DD. I think the ER2XR has better transient control, and the Sony MH755 is just tuned plain better with greater transient density. The Sultan's midrange is fairly thick thanks to the lower mid-range emphasis and the cut to the upper-mids. Certainly inoffensive if not somewhat bloated, but also a bit of a double-edged sword intangibly. It seems to cover up some of the BA timbre, and speaking of which, I think the Sultan is surprisingly decent in terms of coherency. I don't get the impression that it’s particularly disjoint or mismatching note textures.
The problem? This is mostly by virtue of poor resolving capability, and to this effect, the Sultan is heavily circumscribed by its technical chops. It's got that "larger-than-life" quality to its notes, which I don't dislike, but they don't have room to breathe and expand. Imaging, layering, resolving capability, the Sultan is just...
average. On Tom Day's "Where Were We," the Sultan struggles with the most basic of passages; the opening bird chirps sound static, sonic-walled, and there's a subsequent lack of ambiance. As the layers progressively stack, the chirps begin smearing, becoming impossible to locate; the Sultan seems to struggle with anything more than surface-level detail. This holds even more true of my usual Sawano Hiroyuki test tracks. Not once did it feel like the Sultan matched my Moondrop B2, an IEM a
tenth its price, for technicalities much less the other flagship stuff I have on-hand.
And that's a problem, because we haven't even gotten to my biggest gripe: The Sultan is surprisingly fatiguing. Considering the Sultan doesn't have much extension or air to speak of, it might not be readily apparent what's causing this fatigue. It’s not like the Kaiser Encore’s crazy, 6kHz peak. No, the culprit lies in the Sultan’s lower-to-mid treble emphasis; this awkward balance presents itself more strongly over extended listening, especially on treble-intensive tracks like GG's "Galaxy Supernova". Throw in the aforementioned lack of staging and layering chops, and the Sultan frequently comes off as overly congested.
I think I mentioned this earlier, but the toughest IEMs for me to review are stuff like the Sultan. I
do see how this type of overly-thick sound might appeal to some people. However, while the Sultan's not bad, it's also by no means (what I would qualify) good either. It's in a weird spot between mediocrity and something that had the potential to be good; ignoring the subpar technicalities, the tuning lacks direction and artistic vision in my humble opinion. Noble Audio has unmistakably nailed the aesthetics game, and it's nigh time they hopped on their sound one.
Score: 3/10
