There are two different modifications available for the Mbox 3 Pro:
The Mbox 3 Pro Standard Modification consists of completely replacing all of the existing inexpensive stock op-amps with faster, high-grade op-amps that sound much more open, detailed and textured, with far better micro-dynamics. The modification makes the stock Mbox 3 Pro sound quite hazy, undefined and flat in comparison.
The Mbox 3 Pro Premium Modification includes everything in the Standard Mod, but goes a step beyond. In addition to the new op-amps, we also install new audio-grade electrolytic capacitors that dramatically improve bass response and tame the brittle-sounding high end noticeable with the Mbox 3 Pro. Most “affordable” audio gear use low-grade capacitors that will work okay, but just don’t sound very musical in the audio signal paths. We choose premium audio-grade caps that are MADE ESPECIALLY for processing audio signals and make a huge difference in the resulting sound. This kind of rich tone is very difficult, if not impossible, to find in low-powered recording interfaces like the Mbox 3 Pro, but can now be yours at a great price.

The scale is from 1-10, with “1” being unimpressive audio quality and “10” being true audio excellence. This is an exponential scale, so going from “1” to “2” isn’t nearly as big of a jump as going from “9” to “10”.
