I emailed this guy last night to ask about ETA on the OSX version. I think he said March, but I don't have that email box in front of me at the moment. There will be a downloadable demo version for OSX and it will be offered for a limited time at $99. The best part was he gave me links to a bunch of demos. Sometimes things like this get very tiring after awile, but I have my doubts about that in this case. It is very subtle, but a couple of demos that switch back and forth between on and off really demonstrate what it does. On 2-channel material, it literally shifts the image forward, out of the head. On examples that sampled large large halls and reflective rooms, the space expanded very noticably. On some examples that were sampled in a heavily treated recording studio control room, the image shifted forward, as it should, but it remained very dry and tight, just like the difference between playing instruments in a control room vs. a very hard-surfaced room with lots of reflective surfaces.
Subtle. Impressive. I will be downloading the OSX demo as soon as its available and trying this out on recordings I'm very familiar with, including some of my own. The 5.1 and 7.1 movie samples were equally impressive. I've listened to a fair amount of Dolby and Yamaha's headphone surround simulations. Yamaha's is better, IMO, but this was better still. Very subtle and natural. Convincing. It makes the others sound like what they are; an effect.
Almost all headphones are built with "color," because flat doesn't sound natural to us when there are no room reflections. With this product, it's not hard to imagine some dead-flat IEMs sounding very good. An iOS version is on the way as well. This is very exciting stuff for people who listen alone and/or on the move.
