Overall, although it's still initially harder to get to grips with than some rival 'EQ ripper' utilities, I still prefer Harbal, with its more considered approach to improving the final sound of an audio track, the detail of its manual and tutorials, and its helpful on-line user forum hosted by Har-Bal's professional mastering and research engineers. It's a serious tool that can teach you a lot about why your mixes don't sound like commercial tracks, at the same time as improving them.
