OSS 3D is one of the 'essential' apps on my macbook.

The difference in music quality is extraordinary. If you're willing to tweak it and spend some time adjusting levels to your preferred music and saving settings, you really won;t go back.

BUT don't use 2.3b7. Its all messed up, sound is horrible and obviously bugged up and its hogs cpu also, (whereas before it did a little bit during setting changes, but not during regular play)
After not updating for a long time I decided to see if there was something to be gained from the latest version, there isn;t. I'm going backwards until I get one that works...
