Wow, catching up on this thread from being away for three days was less headache than expected!
SlickNick, Porksword, and Knallie,
To simply experience headphone surround, a $25 Turtle Beach DSS (first one, not DSS2) will also use Dolby headphone processing and sound pretty good. A Tritton AX720+ processor or Astro Mixamp will also use Dolby Headphone, they don't improve the sound quality over the DSS (actually have lower quality amps, with background hiss and less volume headroom) but the Mixamp gains chat/game volume mixing as a feature. A lot of times you can use console features instead of the Mixamp dial, but it can be nice to have a dial right there to readjust on the fly.
Next quality step up would be an A/V receiver that offers a headphone surround mode... You get a noticably better amp and DAC than the DSS, but the headphone surround processing might seem slightly less natural than Dolby Headphone (unless you get an antique featuring DH). Expect to pay like ~$200 for a good one, with plenty of wiggle room.
Next step up would be Creative's new Soundblaster X7, $400 new. So far, the most natural sounding surround processing I've heard yet, plus decent Digital-to-Analogue-Conversion (DAC hardware) and amplifier, usb inputs for PC and recent smartphones/devices, optical for console game audio, Bluetooth receiver (and mobile app for adjusting settings), etc. A couple reviews are on Head-Fi now, worth a look if looking to make a system.
Next level up would be a Beyer Headzone or Smith Realizer, I don't know much about them except they apparently sound amazingly holographic and cost over $1000 (and my current budget).
