For anyone wondering how the Arya Stealth Magnet version compares and what’s going on there, it’s essentially the same as the V2 (dust cover change), just with a bit more upper treble. Additionally, it seems to have slightly more bass and lower mids but that’s within the ballpark of unit variation so it’s not a huge difference. All in all, there’s not much difference. Both V2 and V3 are smoother in the mid treble than the V1.
My take is that the stealth magnet Arya (V3) is ever so slightly better in the treble with the addition of extra air at around 12khz, just because that balances out the lower and mid treble peaks a bit more. This gives it a slightly ‘airier’ yet smoother treble presentation overall. But the same strengths of the previous version (and the few weaknesses) are still here, it’s a great sounding headphone.
