I have a first-generation MacBook, which are notorious for having a very low max sound output level when using the built-in speakers. I'm looking for a good software solution (i.e., no suggestions for headphones/external speakers) to boost the maximum sound output-level.
My main criteria is this: I don't want something that's app-specific, such as using VLC's built-in volume control + equalizer. I'm looking for something that either works system-wide for all sound output, or can be used with any app.
The best solution I've run across so far is described here — it details using Audio Hijack Pro to hijack any given app's sound output and boost it with AH's equalizer controls.
While the Audio Hijack solution works okay, what I'd really like to find is a control panel or background app that puts an icon in the menu bar with either a system-wide toggle or an app-selector to toggle the volume boost for the chosen app.
Any alternatives that are better than the Audio Hijack solution?

How About Rogue Amoeba's SoundSource? I'm not sure if it does exactly what you want, but give it a try. The price is right. Otherwise Audio Hijack Pro was going to be my recommendation.
For a hardware solution check out HeadRoom's Total Airhead or Total Bithead, which besides amping up the volume, it will help the sound quality if you don't have the most efficient headphones. This is very dependent on what headphones you have.
