Got a pair of these today. Great set
@Dan Clark. Some initial points:
1. Great build - the self adjusting strap is a big bonus over previous Aeon
2. Possibly the most tonally correct set I have had out of the box - maybe tied with the Audeze Maxwell but those are very different beasts.
3. I could happily live without EQ and its early days but shaving a dB or 2 from the pinna gain hump, small high shelf to roll off above 9k and a little bump to the sub bass improves things for me but I like low bass thump and sensitive to too much 2-4k for my ears - though this could just be tweakers' bias with those adjustments.
4. Not hard to drive in the grand scheme of overhead planars but these will max many a dongle easily especially with some negative pre-amp. Had some headroom on the 3V E1DA 9038D but not a huge amount. About -20 on the RME ADI 2 DAC is plenty loud.
5. Hair and beard are currently reasonably trimmed but doesnt take much seal break to lose the bass.
