You are using alien language to me . All I understood is 5.1 and 7.1. I know the word analog but I have no idea how it works. You mean that the consoles have 5.1 audio? Does that not depend on the game and how the audio was coded? Or is all audio for all games on consoles the same? And how is that helping me since my headphones are stereo? Would that not be "fake" 5.1 or 7.1 from the consoles through my headset?
So forget the ThunderFX and get the Recon usb thingy? How does it compare to the 3 mixamp versions and the 2 dss?
The whole topic of this thread is virtual surround for stereo headphones, and headphones that work well with that audio processing. Rather than retype an explanation again (already have 100s of times in the past), I'll point out that Mad explained it in the first post of this guide thread, and that I explained it in more detail in my "If I knew then..." thread linked in my signature.
We get the same questions often about comparing those processors you mentioned, so I'm making a video comparing them and their setups, which I will post after I get my Mixamp returned around the 23rd.
