I'm used to a full 5.1 setup but whilst I'm staying at a m8's I'm using (quality) earphones, been experimenting with Cmss3D on my Xtreme Gamer whilst playing Arkham City and Max Payne 3 but I don't really get any positional sounds. The helicopter test works ok in the cpl, but in game i think it sounds better with it turned off Would have thought that with Cmss3d, it would fool the game into thinking there were more speakers than just 2, then translate those audio streams into a pseudo stereo surround mix, but the only options I get in Max Payne is headphones or speakers. I don't understand how stereo surround technology can accurately interoperate where sounds are coming from and accurately represent them from a stereo mix. Am I doing it wrong? The problem here is that Figures don't translate in to audio experience. A lot of it is down to personal preference, but as an extreme example, a £5 set of earbuds that advertise a 20hz-20KHz frequency range won't be able to reproduce those frequencies as accurately or with anything like as much definition as a set of £150 earbuds that might have the same range printed on the box. There are so many subjective factors figures would be meaningless.
