Just dropped a Burson V5i in mine. Easiest mod by far and as dramatic a quality increase as dropping a '54 RCA blackplate in my TA-03. I also ordered mine on the 9th, arrived on the 30th. The RC tracking number they give you will not be scanned by USPS stateside, so all you'll ever see is...

I set 256 on everything because while the device will switch to the input format automatically, Foobar does not handle it as well. After a few transitions from 64 to 256 Foobar will get the driver stuck and report that "the device does not support 702,500hz" or something like that.

I play 256 as much as possible. It is somewhat finicky in regards to other audio applications borrowing the audio device. If you are looking for ASIOProxy settings, they're fairly easy. Use the latest foo_input_sacd, foo_dsd_asio and foo_output_asio (not from the xDuoo disc). Ignore the xDuoo...
