To me it seems, HiFiMan has listened to all the criticism they received with all previous Arya versions and tuned the 'organic' to fit the taste of those not liking the Arya yet. More bass, tamed treble, as a promise of 'organic' sound I also expect better texture in mids. I always felt the Arya too vast in soundstage, so I wouldn't mind a little more focus and precision either, even if it comes at a price of smaller spatial sensation.
The 'organic' seems to address all the issues I had with previous Arya models, so this makes me really intrigued. The fact it comes in $300 cheaper is just the cherry on the cake. Is HiFiMan up for a winner here? I can't tell, until I audition/review them, but if the recipe worked, they might well become HiFiMan's best sellers.
