I've always hoped that Audeze would do this as I think they'd sound excellent. They wouldn't roll off so quickly in the bass like the original Sigma and they'd be able to get a nice soundstage out of an ortho driver. I'll keep my fingers crossed that one of the manufacturers out there adopts the Sigma concept.
I just hope that HiFiMAN isn't the first to do that. I'd have to hire rhythmdevils to punch their treble in the face. (The HiFiMAN orthos have too much treble, especially cymbals, for me)
It would be a chance to possibly get some "wow" style swim around the head soundstage from an ortho. The big difficulty is that a design like that would be an ergonomic disaster with a big heavy ortho driver at the front of some big cups pulling the headphones down.
I've never heard a Stax Sigma. It's on my "I hope I get to hear it sometime" list. Could be quite interesting for headphone sound.
