I was examining how good KBEAR Believe the pure-beryllium affordable IEM is compared to similar characteristics Moondrop Aria.
For consistency I used same cable (Moondrop 6N Single Crystal pure copper OCC) for Aria.
A miracle happened, the persistent muffled midrange of Aria was caused by the stock cable!
With same condition Aria (raw) is just slightly behind Believe(raw) in terms of resolution and speed. Making Aria 84/100 IEM. My first A grade for sub$100.
If muffled / half-dead vocal /piano is your thumbs down for Aria, you now know the culprit is that 1: hex shape acoustic dumper filter 2: stock cable.
Cable notes:
Moondrop 6N OCC single crystal pure copper cable($59) : slight U arrangements from original V tuning of Aria, comes with switchable 2.5mm/3.5mm/4.5mm jacks

KBEAR pure silver cable ($33):
More flat arrangements from original V tuning of Aria, options to choose 2.5mm,3.5mm, 4.5mm at the time of purchase; highly recommendable for recabling for Aria(raw)
