No, no need for $2000 headphones, whatever you have will do. As to anything on the table for Stereo, that's pretty much all I use it for, if sound quality is of any importance to you then . . .
Try the original Blackhole and or MicroPitch up against the Immersiver versions and all should become clear, unless one is deaf in one ear and can't hear out the other.
Anderton has some interesting stuff to read in his 'Friday Tips of the week' or what ever it's called over on the PreSonus/Studio One site/Blog, he goes on to say that it is soon going to be, and in some cases already is??, a requirement to have immersive versions along with the normal stereo version to be able to upload a persons work to the various sites? Who knows? Interesting reads though and some good information and examples on the subject, it's back a ways now.
