I think Head-fiers are just conspiring to make uninformed consumers spend more money. This "hiss" from the DSS is obviously manufactured to make ordinary people spend double the price on a "better" piece of technology.
Totally kidding by the way.
Does anyone know if it's actually true that you can plug the PS3 Chat cable from the Mixamp 5.8 in to your computer to receieve audio on your PC? The wired Mixamp looks really nice because I can connect a 3.5mm/3.5mm or USB/USB to my computer and receieve stereo sound, but I don't know if you get that feature on the wireless Mixamp. My computer has no optical port.
