Used this to rip some of my new CD's on Ubuntu 14.04 (64 bit) and it was a bit unstable until I enabled the spin up CD before ripping feature. After that it was fine and converted them all into ALAC. Ripped them well and sounded just as good as before through my Monitor Audio speakers. The layout of the GUI is a little bland by todays standards but I'm not to concerned about that, the quality of the rip is more important. Overall I'll be using this from now on as my new CD ripper / converter. Keep up the excellent work!
