If I may jump in:
Arya Organic and HE1000 Stealth definitely a brighter, airier, and thinner sounding headphone than E3. All of them have decent attack notes (some called it macro dynamic?), but none of them is hard hitter like zmf caldera or abyss.
I can hear bass detail (like texture in Double Bass or Bass Guitar) a little better with E3 than the Hifimans.
Personally HE1000/Arya has really different sound signature compared to E3. Hifiman is more "audiophile" tuning, big wow factor with very apparent spacious soundstage, plenty of sparkle detail, sweet a bit mellow in vocal, in opposed of neutral, tight, and accurate sound presentation of E3.
