This is the place to post your soundcard/audio interface performance tests...
Here's mine:
M-Audio FireWire Solo

here's a link if you need more detailed info: https://app.box.com/s/hfgdsnfoe5yylrwf9t98yyey7wgsagno
but basically here are the results: note: not sure what happened, but @ 88.2k, the freq response isn't accurate of course, should be more or less the same as with the other sample rates.
For those that don't know and are interested, RightMark Audio is a software that helps test performance of your equipment, on your soundcard/audio interface, just form a feedback loop (connect output into input) and run the tests. (of course you won't want any speakers turned on when doing this, sorry but needed to mention in case anyone forgets they have a secondary system connected or whatever...)
I used the free version, more than enought to show results I'd say: http://audio.rightmark.org/index_new.shtml
