After 100 hours of burnin, just removed nozzle filter from Aria.
The muffled mid is almost gone!
-The sound is much more “lively”, finally a clear vision from top to bottom!
-The filter seemed still reattach-able
- do note I use Xelastec M (L makes it dark) eartip after rolling many others
-Trade off: a bit off-phase sub-bass, treble gets boosted as well, so it’s not moondrop’s house curve anymore
-diffusion field also got a bit narrower
-there are another layer of acoustic filter inside of the nozzle filter
-beware of proper fit, Aria needs deeper insertion than Starfield and KXXS, otherwise it will be a dead hollow sound; try to push it and listen to the sound change, when you get a completely sealed air vent hole, the magic kicks in, this is noticeable by driver flex sound due to insertion air pressure.
- I’d say this will bring Aria’s sound sigunature to bright neutral ( hints of U still exists)
-post burn-in, air presentation still seemed a bit rough but forgivable
bottomline: it’s not a magic to make Aria to top-of-the-line IEMs, but it is a significant technicality improvement.
I would refer Aria, with xelastec M, deeper insertion & full seal, removed nozzle, post 100 hr burn-in, as Mini-Softears RSV.
Sound image coordination and vector presentation is not what RSV level could offer, but as far as resolution and diffusion field width, it comes to closer region.
highly recommended to Aria owners
now Aria hits on top of my list among KXXS/Starfield. It’s definitely not a “budget KXXS or Starfield” anymore.
Resolution is higher than NF Audio NM2+ now.
