I don't own the Eikon, just the Atticus. As much as I enjoy it, it overlaps with several other headphones I own, so it hasn't been a huge priority on my "need to buy" list.
On the Abyss Phi, I'll say this... at least Joe's headphones are worth their astronomical asking price. And I think he did right by his current customers by offering the driver upgrade for $1,500, instead of immediately launching an Abyss 2 or making one of those "silent revisions" we've all come to know and love so much from other brands. I'll be interested to hear it for myself, because he sounds really, really excited about it.
I guess I misread it...I thought he said 1500.00 per driver,which would be 3k....and for 3k just buy the Phi and keep your old Abyss.
Yeah its not as offensive as some other companies business tactics...Curious though how the bass will be impacted by the higher sensitivity.
