i don't think installing it manually is much of a stretch for someone who wants to participate in a listening test. 1) download the installer: http://www.foobar2000.org/download2) run the installer3) download foo_abx http://www.foobar2000.org/components/view/foo_abx4) file>preferences>components>click the "install" button and browse to the saved zip file.5) restart foobar when prompted. add 2 files to playlist. right click>can't remember the exact option as i don't have it installed.or maybe consider a standalone ABX application? sorry i don't have any recommendations though.
