The flaming part wasn't addressed to Anax in particular. Personally I don't care much for what's happening here, I have no dog in that fight and don't intend to engage one. Still it's always noteworthy when the Godwin point is getting close, and Anax got damn close here.
Thanks for the work Purrin, interesting as usual. According to that website http://www.sengpielaudio.com/calculator-thd.htm, your math is correct.
Does anyone know the address of the web application for distortion ? There's always the tool at klippel.de, but I'd like to try some other ones if possible.
