See here for an example.
Software can be downloaded and evaluated here.

we found most of customer from diyaudio like sigma file debuging and try all audio parameter themselves , of course lots of audiophile like enjoy fixed audio parameter amp .
so we decide produce two version of this type amp, one for expert and open sigma files, one for audiophile with fixed parameter .
we have some USBI downloader here, if necessary ,tell us.
