Creative's SBX products have a "scout mode" toggle button that tries to do that. Haven't tested that feature much though so can't say beyond that.
No experience with the Hel but I think MLE mentioned a review incoming for that. What I will say about how it looks on paper is that while I'm sure it sounds great and can drive anything, as something that's marketed primarily as a gaming dac/amp, it lacks almost every feature one would normally associate with that kind of device. No optical input for dolby digital 5.1 decoding, no multichannel PCM support for PC, no control panel software etc.
It will likely sound fine, great even, if you are just happy pumping vanilla stereo or pre-binauralised surround content into it. But if you are interested in VSS (and assuming you don't intend on feeding the Hel pre-rendered VSS from a dedicated device using the line-in), you would be limited to using a game's inbuilt headphone virtual surround mix if it has one (some do, some don't), using the DTS headphone X or Dolby Atmos Headphone apps for windows or else something like Hesuvi because by itself the Hel appears to lack the capacity to process and interpret a discrete multichannel source feed.
