I prefer Apple AUGraphicEQ over VOX Equalizer.
Fortunately it's possible to use it through Audio Units.
Unfortunately it's not possible to save custom presets because "save as" is missing in the presets pop-up menu.
All I can do is to select existing presets, many of them created by myself in AU Lab application.
Yet, when I run very old VOX 0.3 beta 2 on the very same machine I found the "save as" is existing and I can create custom presets that I can use in VOX 2.6.
See screenshots attached.
