6moons is painful to read coz they talk a lot of nonsense:
-the Burson HA-160D uses an isochronous Tenor chip...not quite async
-they say "1pmm 12MHz TCXO" as if it were the holy grail...but it's not. The holy grail is two have 2 low jitter(and the ppm resolution has nothing to do w/ jitter) discrete clocks that are exact multiples of 44.1 and 48...and this 12MHz clock is not here to "reclock", it's here to work as a reference to the DSP.
on page 6 of the manual: http://www.skyview3d.com/skvwtp/Kingrex/UC192/KingRexUC192D2DconverterUserManual.pdf
you can read that the unit can burst into flames if you leave it plugged in and not in use...it's a joke, right?
on the same page, they also say that if you see/smell smoke, you should unplug it...now that makes sense.
the proprietary drivers are from VIA and they seem to provide KS on XP, nice to see that VIA has a USB chip available...and its firmware can be updated via USB, always a nice touch.
