Cyber_Murphy Posted September 4, 2012 Posted September 4, 2012 Hi Steve, Just wondering how it performs on USB input? Do you need to install custom drivers, or does Windows just detect the device natively?? Also, what is the "Flavour" button on the front?? Thanks.. CM
SteveC Posted September 4, 2012 Author Posted September 4, 2012 I have tested it through USB and it sounds fine to me. Windows 7 PC just picked up the driver no problem. "Flavor" (Flavour) button cycles through 9 different types of digital filtering. See the attached manual which lists the filters.
pete_mac Posted September 4, 2012 Posted September 4, 2012 The 3.1 doesn't require drivers as it runs the TE7022 chip. The later 3.2 runs the TE8022 and requires drivers as it offers asynchronous USB.

SteveC Posted September 4, 2012 Author Posted September 4, 2012 Sorry I looked up the wrong price before. Changed to $300 shipped.
SteveC Posted September 4, 2012 Author Posted September 4, 2012 Not sure what you mean by "upgraded chipset" ? Standard 3.1 with the DIR9001 S/PDIF Interface.
PorkBun69s Posted September 4, 2012 Posted September 4, 2012 You need to listen to a Ref7 or 7.1 dac...

I just get so confused with "what's what" trying to follow the Audio GD stuff.. Their website is terrible,, and any Audio Gd threads on here are quite interesting, but it seems unles you've been following their developments over time, it makes it hard to figure out what's what,, well for me it does anyway Ta
